Patent Description:
In a construction process of a building, materials and/or workers need to be conveyed up and down between floors basically built well. Under such need, a jumping elevator (or referred to as jumping lift) system is typically used in the construction process of the building; with an elevator car of the jumping elevator system traveling up and down in a well-built hoistway (or referred to as a lift shaft) of the building, materials and/or workers can be conveniently conveyed between different landings. Also, as the construction process of the building advances continuously, the height or level of the hoistway also advances gradually, and the traveling height of the elevator car of the jumping elevator system in the hoistway also needs to be increased continuously, generally through a jumping platform.

Known conventional elevator systems typically use ropes for lifting, and generally require an elevator machine room to be provided to accommodate drives such as tractor to pull the ropes, thereby lifting the elevator car. Therefore, corresponding space is leaved generally in the hoistway (e.g., at the top of the hoistway) of the building to provide the elevator machine rooms.

For a jumping elevator system, an elevator machine room also needs to be provided to contain a tractor and the like. At present, the elevator machine room of the jumping elevator system is generally arranged in a hoist, and even the elevator machine room is arranged on a jumping platform and can jump along with the jumping platform.

Moreover, before the jumping platform jumps up, guide rails need to be extended and newly extended guide rails need to be positioned and mounted on the hoistway, thereby preparing for extending traveling height of elevator car.

<CIT> discloses a lift system which is arranged in a lift shaft of a building in the construction phase, and grows with the building by means of at least one lifting process, said system comprising a machine platform with a lift drive machine and a lift cage suspended on the machine platform by means of at least one carrier means, said lift cage being able to be raised during the lifting process.

<CIT> discloses a technical auxiliary platform for temporary use in an elevator shaft.

<CIT> discloses a method to manufacture an elevator including an elevator car and a movable supporting platform.

<CIT> discloses a method and elevator arrangement wherein a roof structure is lifted higher in a hoistway so as to make more room below the roof structure, the roof structure being a movable roof structure, and in that the movable roof structure is lifted in the hoistway taking support for the lift from a second movable support structure mounted in the hoistway above the roof structure. <CIT> discloses the preamble of claims <NUM> and <NUM>.

<FIG> shows a structural schematic of a jumping elevator system in accordance with an embodiment of the present invention; <FIG> illustrate a jumping process of the jumping elevator system of the embodiment shown in <FIG> based on the jumping method of the embodiment shown in <FIG>. The jumping elevator system illustrated in <FIG> and its jumping principle are described below in connection with <FIG>, <FIG>.

As shown in <FIG>, a jumping elevator system <NUM> can be used during construction process of a building, for example, materials and/or workers can be conveyed by an elevator car <NUM>. The hoistway <NUM> corresponds to a hoistway of a building in a construction process; as the construction process advances, the height of an well-built hoistway <NUM> as shown in <FIG> will continue to increase, which requires the jump elevator system <NUM> to perform a jumping operation (or referred to as a climbing operation) in order to enable the jump elevator system <NUM> to serve a higher landing. <FIG> has shown a part of the well-built landings <NUM>, e.g., landing <NUM><NUM>,. , landing <NUM>N, landing <NUM>N+<NUM>, landing <NUM>N+<NUM>, etc.; it will be understood that the subscript of sign <NUM> corresponds to floor number at which the landing is located, and the particular number of floors of a building is not limiting.

With reference to <FIG> and <FIG>, the jumping elevator system <NUM> can include the elevator car <NUM>, a counterweight <NUM> disposed in the hoistway <NUM>, an elevator machine room <NUM>, a jumping platform <NUM>, a lifting assembly, and a temporary working platform <NUM> (as shown in <FIG>), optionally further includes a pulley assembly, etc. Therein, by means of the lifting assembly, the jumping platform <NUM> can jump as the height or level of the well-built hoistway <NUM> of the building increases.

Wherein the elevator machine room <NUM> is independently arranged relative to the jumping platform <NUM> and does not jump along with the jumping platform <NUM>. The elevator machine room <NUM> can be provided with a tractor (not shown in the figures) and a traction sheave <NUM>, and can also be provided with electrical equipment such as a control cabinet. In consideration that the elevator machine room <NUM> has a critical environmental requirement but it is difficult to provide a safe and dry environment (e.g., the bottom of the hoistway <NUM> prone to water accumulation, etc.) for the hoistway <NUM> of a building not constructed well, the elevator machine room <NUM> is moved outside of the hoistway <NUM> in embodiments of the present invention, for example, the elevator machine room <NUM> is fixed to the landing <NUM> outside of the hoistway <NUM>; thus the elevator machine room <NUM> also does not need to be lifted by the lifting assembly or the like and also does not jump along with the jumping platform <NUM>. The floor number of the landing <NUM> to which the elevator machine room <NUM> is fixed is not limiting, and the elevator machine room <NUM> may, but is not limited to, be fixedly disposed on the landing <NUM><NUM>, e.g., may also be fixed on other landing <NUM> as desired.

The elevator machine room <NUM> may be fixedly mounted as a temporary elevator machine room on, for example, the landing <NUM><NUM>; in an embodiment, the temporary elevator machine room can be removed, and then be transferred and installed to a predetermined location in the hoistway <NUM> (e.g., the top of the hoistway <NUM>) for installation after completing the construction of the building, so as to transform the jumping elevator system <NUM> of the embodiment of the invention into a conventional elevator system normally used in an well-built building, which can realize the recycling of components (such as a tractor and the like) of the elevator machine room <NUM>, and the cost is greatly reduced for a constructor of the building; moreover, it is also very convenient for operations of transferring and installing the elevator machine room <NUM> on the landing <NUM>. The elevator machine room <NUM> can be selectively disposed adjacent to the hoistway <NUM>, which will reduce the difficulty of arranging the pulley assembly of the following embodiments and also facilitate reducing traction power requirement on the tractor.

Therein, the elevator car <NUM> can travel up and down along the guide rail <NUM> in the well-built hoistway <NUM> of the building under a traction, for example, of the traction sheave <NUM>. It should be noted that the guide rail <NUM> is a basic component for supporting the elevator car <NUM> to travel in the hoistway <NUM>; thus, if it is desired that the elevator car <NUM> could travel to certain height, such as landing <NUM>N +<NUM>, the guide rail <NUM> in the hoistway <NUM> should be positioned and mounted to at least landing <NUM>N+<NUM> or above the landing <NUM>N+<NUM>. <FIG> also illustrate a positioning and mounting process of the guide rail <NUM> in the hoistway <NUM>, where 930a denotes an well-mounted guide rail, and 930b denotes a guide rail to be mounted. In an embodiment, the mounting of the guide rail <NUM> may be reinforced sectionally (e.g., secured to a wall of the hoistway <NUM>) on the hoistway <NUM> using a plurality of guide rail brackets <NUM>, where 931a denotes the guide rail bracket applied on the well-mounted guide rail 930a,, and 931b denotes the guide rail bracket applied on the guide rail 930b to be mounted correspondingly.

With continued reference to <FIG>, the pulley assembly can transmit traction from the traction sheave <NUM> to the elevator car <NUM> or counterweight <NUM>, which may include a rope <NUM>, one or more top guide sheaves <NUM>, and one or more bottom guide sheaves <NUM>.

The rope <NUM> may be various types of traction member (e.g., banded rope) adaptable for elevator systems, whose cross-sectional shape may be generally circular, square, etc., and the materials used of which are not limiting. The rope <NUM> has two ends, i.e., a first end <NUM> and a second end <NUM>, which are both secured to the jumping platform <NUM> (e.g., secured to a spandrel girder of the jumping platform <NUM>) in the embodiment shown in <FIG> so that it can jump along with the jumping platform <NUM>.

With continued reference to <FIG>, one or more top guide sheaves are disposed on the jumping platform <NUM> and capable of jumping along with the jumping platform <NUM>, and the bottom guide sheaves are disposed corresponding to the elevator machine room <NUM>, which can be partially disposed in the hoistway <NUM>, or can be partially disposed outside of the hoistway <NUM> (e.g., even the bottom guide sheave 144b is disposed in the elevator machine room <NUM>). The top guide sheaves and the bottom guide sheaves are arranged to guide the rope <NUM> to extend at least from the hoistway <NUM> to the traction sheave <NUM> in the elevator machine room <NUM> outside of the hoistway <NUM>, such that the elevator machine room <NUM> can be fixed to a certain landing <NUM> outside of the hoistway <NUM>, without limitation of fixing in the hoistway <NUM>, improving the flexibility of the arrangement of the elevator machine room <NUM>, and conveniently introducing traction from the traction sheave <NUM> outside of hoistway <NUM> to equipment in hoistway <NUM> (e.g. elevator car <NUM> or counterweight <NUM>).

In an embodiment, the arrangement of the top guide sheaves and the bottom guide sheaves <NUM> as well as the winding of the rope <NUM> can be selected to achieve a traction ratio (or referred to as a suspension ratio) of <NUM>: <NUM>, for example, a roof pulley <NUM> can also be provided at the top of the elevator car <NUM> and a diverting sheave <NUM> can be provided at the top of the counterweight <NUM>; the top guide sheaves and the bottom guide sheaves are further arranged to guide the rope <NUM> to extend at least from the roof pulley <NUM> toward the traction sheave <NUM> in the elevator machine room <NUM> outside of the hoistway <NUM> such that the tractor can transmit a traction force to the top of the elevator car <NUM> through the pulley assembly. In this way, it can achieve a traction ratio of <NUM>: <NUM> for lifting the elevator car <NUM> from the top of the elevator car <NUM>.

Referring to <FIG>, a specific arrangement of the pulley assembly is presented by way of example in detail. A rope <NUM> extends downward from the first end <NUM>, wraps through the roof pulley <NUM>, extends upwards and wraps through the first top guide sheave 143a of the top guide sheave <NUM>, extends downwards and wraps through the first bottom guide sheave 144a of the bottom guide sheave, and continues to extend to the traction sheave <NUM> of the elevator machine room <NUM>; after wrapping through the traction sheave <NUM>, the rope the rope <NUM> extends laterally and wraps through the second bottom guide sheave 144b of the bottom guide sheave <NUM>, extends upwards and wraps through the second top guide sheave 143b of the top guide sheave <NUM>, and continues to extend downwards to the diverting sheave <NUM> at the top of the counterweight <NUM>, and finally extends upwards and is secured at the second end <NUM>.

In an embodiment, there may be two first top guide sheaves 143a and they are arranged laterally on the jumping platform <NUM>, thereby guiding the rope <NUM> in a left-right direction to guide in a direction toward the elevator machine room <NUM>; the first bottom guide sheave 144a may be one and it can be disposed in the hoistway <NUM> and proximate to the elevator machine room <NUM>; the second bottom guide sheaves 144b may be two and arranged approximately laterally, one of which may be disposed in the elevator machine room <NUM> and the other which is disposed in the hoistway <NUM>, thereby guiding the rope <NUM> in a left-right direction to guide in a direction toward the hoistway <NUM>.

It should be noted that the pulley assembly may achieve the traction ratio of <NUM>: <NUM> in other arrangements. By way of example, the diverting sheave <NUM> may also be not provided on the counterweight <NUM> of <FIG>, as shown in <FIG>, with the second end <NUM> of the rope <NUM> secured to the counterweight <NUM>, such that an arrangement of the elevator car with a roof pulley and the counterweight without a sheave is achieved.

Still referring to <FIG>, the jumping platform <NUM> may be removably fixed at a landing (e.g., landing <NUM>N); when the jumping operation is not needed, the jumping platform <NUM> is fixed at the landing <NUM>N, thereby providing suspension support for the elevator car <NUM>, the counterweight <NUM> and the like; when the jumping operation is needed, its fixation relative to the landing <NUM>N is dismounted, thereby preparing for jumping to other landing.

In an embodiment, the jumping platform <NUM> includes a second upright <NUM> and a cable-stayed member <NUM>, and the second upright <NUM> and the cable-stayed member <NUM> are deposed for conveniently and removably fixing the jumping platform <NUM> at certain landing; wherein the second upright <NUM> is removably positioned and mounted relative to the landing <NUM>N (e.g., stuck at a landing door gate of the landing <NUM>N in up and down direction), the end of jumping platform <NUM>, close to the lower end of second upright <NUM>, is removably mounted on the landing 920N (e.g., projected to the floor of the landing <NUM>N by a retractable member, thereby simply lapping the landing <NUM>N); and two ends of the cable-stayed member <NUM> are pivotably connected to the upper end of the second upright <NUM> and the jumping platform <NUM> respectively; therefore, the cable-stayed member <NUM>, the second upright <NUM> and the right end part of the jumping platform <NUM> can construct a relatively stable structure with right triangle, and the jumping platform <NUM> is fixedly mounted in the hoistway <NUM> corresponding to the landing <NUM>N. When the jumping platform <NUM> needs to be removed, the second upright <NUM> can be dismounted from the landing <NUM>N, and the second upright <NUM> and the cable-stayed member <NUM> can be rotated and placed on the jumping platform <NUM>, ready for removing the jumping platform <NUM>. After the jumping platform <NUM> jumps to the next landing (e.g., landing <NUM>N+<NUM>), the second upright <NUM> is pulled out and positioned and mounted at the landing <NUM>N+<NUM>, so that its operation is very convenient.

It is to be noted that, since no elevator machine room is provided on the jumping platform <NUM>, the jumping platform <NUM> can be implemented in a relatively simple structure and is lightweight, for example, the jumping platform <NUM> can be implemented in a simple spandrel girder frame or the like and occupies a small hoistway space in the up-down direction; moreover, the jumping platform <NUM> also thus can be implemented at low cost even though the jumping platform <NUM> did not be transformed to a component of the conventional elevator system after the building construction is completed, the cost is low for the constructor of the building. In addition, the jumping platform <NUM> can be reused in a different jumping elevator system for manufacturers of jumping elevator.

Still referring to <FIG>, the lifting assembly in an embodiment includes a hoisting member <NUM>, a hoist <NUM>, a suspension beam <NUM>, and a diverting pulley <NUM> mounted on the suspension beam <NUM>. The lifting assembly may be configured to lift the jumping platform <NUM> to a higher height when the height of the hoistway <NUM> is increased, and further lifting the elevator car <NUM> after lifting the jumping platform <NUM> so as to extend its traveling distance in the hoistway <NUM>. It is to be noted that rope compensation may be provided from, for example, the first end <NUM> when lifting the elevator car <NUM>, specifically a rope compensating component (not shown in figures) cab be provided at a location corresponding to the first end <NUM>.

Due to the fact that the jumping platform <NUM> is lightweight (because the elevator machine room is not provided on the jumping platform <NUM>) and the jumping platform <NUM> and the elevator car <NUM> are lifted separately, the lifting power requirement for the lifting assembly is greatly reduced, which favors to simplify the structural design of the lifting assembly and saving the construction cost of a building.

It will be appreciated that, prior to lifting the elevator car <NUM>, the lifting assembly is reloaded on the elevator car <NUM> from the jumping platform <NUM>; specifically, the hoist <NUM> is removably mounted on the jumping platform <NUM> or the elevator car <NUM>, and the hoisting member <NUM> (e.g., a rope) may extend from the hoist <NUM>, wrap though the diverting pulley <NUM>, and extend onto the jumping platform <NUM> or the elevator car <NUM>; in such, it is easy to reload the hoist <NUM> and the hoisting member <NUM> between the jumping platform <NUM> and the elevator car <NUM>. Specifically, one end of the suspension beam <NUM> can be hinged and fixed to the landing <NUM>N, the other end of the suspension beam <NUM> is in lap joint with the hoistway <NUM>, thereby the dismounting of the lifting assembly relative to the landing <NUM> is easy, and the workload of the jumping operation is reduced.

In view that the power requirement on the hoist <NUM> are greatly reduced, the hoist <NUM> can be selectively implemented by a cable climber, which is low in cost and small in volume.

It should be noted that a fixing member (e.g., suspension, safety clamp, etc.) may be provided on the corresponding elevator car <NUM>. The elevator car <NUM> can be fixed to the guide rail <NUM> by the fixing member during lifting of the jumping platform <NUM>, thus free lifting of the jumping platform <NUM> is unaffected from the elevator car <NUM>.

Referring to <FIG>, the jumping elevator system <NUM> also includes a temporary working platform <NUM> used in the jumping process. The temporary working platform <NUM> can be independently arranged relative to the jumping platform <NUM>, and the temporary working platform <NUM> is provided for preliminarily positioning and mounting the guide rail 930b to be reinforced, jointed at a second height (e.g., the landing <NUM>N), relative to the hoistway <NUM> prior to lifting the jumping platform <NUM> from the second height (e.g., landing <NUM>N); specifically, the temporary working platform <NUM> is positioned and installed on the landing <NUM>N+<NUM> and placed in the hoistway <NUM>, thereby providing a worker <NUM> with a working platform in the hoistway <NUM>; the worker <NUM> can conveniently mount the guide rail bracket 931b on the wall of the hoistway <NUM>, so that the guide rail 930b to be mounted is primarily positioned and mounted relative to the hoistway <NUM>.

In an embodiment, the temporary working platform <NUM> is positioned and mounted on a landing <NUM> (e.g., landing <NUM>N+<NUM>) corresponding to a first height by a first uprights <NUM>. After completing the work of preliminary positioning and installing for the guide rail 930b, the temporary working platform <NUM> can be removed from the landing <NUM>N+<NUM> and continue to be applied during the next jumping operation. The temporary working platform <NUM> can be realized by a simple steel structure frame, is low in manufacturing cost and can be shared by a plurality of jumping elevator systems <NUM> in a plurality of hoistways <NUM>, so that the construction cost of a building can be reduced. Also, in conjunction with the following example illustration of the jumping method, it will be appreciated that the temporary working platform <NUM> will be highly advantageous to avoid the use of scaffolding in the hoistway <NUM> to position and mount a newly extending rail 930b.

<FIG> shows a structural schematic of a jumping elevator system in accordance with another embodiment of the present invention. Compared to the embodiment of jumping elevator system <NUM> shown in <FIG>, the jumping elevator system <NUM> has the main difference lying in that the arrangement of the pulley assembly thereof is different so as to achieve different traction ratio, and the traction ratio of the jumping elevator system <NUM> is <NUM>: <NUM>.

Referring to <FIG>, the top of the elevator car <NUM> is not provided with a roof pulley, nor is the top of the counterweight <NUM> provided with a diverting sheave, and the first end <NUM> of the rope <NUM> is secured to the top of the elevator car <NUM>, the rope <NUM> extends upwards from the first end <NUM> and wraps through the one or more first top guide sheaves 143a, extends downwards and wraps through the first bottom guide sheave 144a, and continues to extend to the traction sheave <NUM> of the elevator machine room <NUM>; after wrapping through the traction sheave <NUM>, the rope <NUM> then extends laterally and wraps through one or more second bottom guide sheaves 144b, extends upwards and wraps through a second top guide sheave 143b of the top guide sheave <NUM>, and continues downwards to the counterweight <NUM>. In this way a traction ratio of <NUM>: <NUM> of the jumping elevator system <NUM> can be specifically achieved.

In other embodiment, the top diverting sheave <NUM> as shown in <FIG> can also be provided on the counterweight <NUM> in <FIG>, through which the rope <NUM> wraps and extends upwards to the second end <NUM>, such that an arrangement of the elevator car without a roof pulley and the counterweight with a sheave is achieved.

Based on the above teachings of the arrangements of pulley assemblies of <FIG> and <FIG>, it will be appreciated that pulley assembly arrangements corresponding to other traction ratios may also be applied in the present invention.

<FIG> shows a flowchart of a method of jumping a jumping elevator system according to an embodiment of the present invention; <FIG> illustrate a jumping process of the jumping elevator system of the embodiment shown in <FIG> based on the jumping method of the embodiment shown in <FIG>, wherein, <FIG> illustrates the jumping elevator system preparing for jumping from the landing <NUM>N, <FIG> illustrates installing the temporary working platform from the landing <NUM>N+<NUM> for preliminarily positioning and mounting guide rails in the hoistway, <FIG> illustrates the use of the lifting assembly to lift the jumping platform from the landing <NUM>N to approximately the landing <NUM>N+<NUM>, <FIG> illustrates lifting the elevator car progressively starting from the landing <NUM>N-<NUM> by use of the lifting assembly and positioning and mounting the guide rails segment by segment on the top of the elevator car, <FIG> illustrates that the elevator car is lifted to the landing <NUM>N+<NUM> by use of the lifting assembly and all guide rails are positioned and mounted well segment by segment on the top of the elevator car, and <FIG> illustrates that the jumping elevator system completes a jumping operation and is ready to regain entering normal elevator operation. The operating principle of the jumping elevator system of the embodiment shown in <FIG> and an embodiment of jumping method of the invention are illustrated by example below in connection with <FIG>.

Firstly, in step S310, referring to <FIG>, preparatory works are completed prior to the jumping, which specially includes securing the elevator car <NUM> to an mounted guide rail 930a below the second height (e.g., a height corresponding to the landing <NUM>N) by securing members such as safety clamps, suspensions, etc., securing the counterweight <NUM> in the hoistway <NUM> (e.g., securing the counterweight <NUM> in the bottom of the hoistway <NUM> by securing portion <NUM>);.

In step S320, the temporary working platform <NUM> is positioned and mounted on a landing (e.g., landing <NUM>N+<NUM>) corresponding to the first height via the first upright <NUM>, such that the worker <NUM> can conveniently enter from the landing <NUM>N+<NUM> onto the temporary working platform <NUM> and operate in the hoistway <NUM>.

In step S330, referring to <FIG>, the guide rail 930b to be mounted, jointed at the second height, is preliminary positioned and mounted in the hoistway <NUM> corresponding to approximately the first height (e.g., in the hoistway corresponding to the landing <NUM>N+<NUM>) by means of the temporary working platform <NUM>, for instance, the guide rail 930b hoisted into the hoistway <NUM> is fastened relative to the hoistway <NUM> at the first height with the guide rail bracket 931b. It will be understood that, in consideration of safety requirements, the guide rail 930b with such preliminary positioning and mounting conditions is not suitable for guiding the elevator car <NUM> to travel thereon.

In step S340, the temporary working platform <NUM> is removed from the landing <NUM>N +<NUM>, that is, removing the temporary working platform <NUM> from a position of the hoistway <NUM> corresponding to the first height, thereby unaffecting subsequent lifting operations.

In step S350, referring to <FIG>, the jumping platform <NUM> is lifted from the landing <NUM>N to the landing <NUM>N+<NUM> by use of the lifting assembly; as desired, in other embodiment, it is also possible to lift the jumping platform <NUM> from the landing <NUM>N to the landing <NUM>N+<NUM>; that is say, in this step, the lifting assembly may be used to lift the jumping platform <NUM> from the second height to a third height, wherein the third height is greater than the second height and less than or equal to the first height. In this step, since the jumping platform <NUM> is lightweight and no worker <NUM> is standing on it, it can be done relatively quickly.

In step S360, referring to <FIG>, the lifting assembly is reloaded on the elevator car <NUM> from the jumping platform <NUM>, specifically, the hoist <NUM> and the hoisting member <NUM> may be removed from the jumping platform <NUM> firstly and then mounted respectively on the top of the elevator car <NUM>, thereby preparing for performing a lifting operation on the elevator car <NUM>.

In step S370, referring to <FIG> and <FIG>, the elevator car <NUM> is lifted by use of the lifting assembly to extend its traveling distance in the hoistway <NUM>, and operations is performed on the top of the elevator car <NUM> during lifting of the elevator car <NUM> for sectionally reinforcing the mounting of the guide rails 930b to be mounted. It will be appreciated that, prior to lifting the elevator car <NUM>, the fixation of the elevator car <NUM> relative to the guide rail 930a can be released. It will be appreciated that, in the process of lifting the elevator car <NUM> by the lifting assembly, the lifting assembly and the elevator car <NUM> together provide the worker <NUM> with a working platform for reinforcing the mounting of the guide rail 930b; the reinforcement of mounting may specifically refer to mounting the guide rail 930b to the wall of the hoistway <NUM> with a plurality of guide rail brackets <NUM>.

In step S370, the worker <NUM> can stand on top of the elevator car <NUM> for performing mounting operation of such as the guide rail bracket <NUM>, and the hoisting member <NUM> of the lifting assembly and the rope <NUM> of the pulley assembly can provide a good safety guarantee for the lifting process of the elevator car <NUM>; the mounting of guide rail 930b is reinforced sectionally during progressive lifting of the elevator car <NUM>, thereby providing guide rail segments with enough safety for the elevator car <NUM> in the subsequent lifting process. By way of example, through this step S370, not only is the guide rails 930b below the landing <NUM>N+<NUM> positioned and mounted well, the elevator car <NUM> is also lifted relative to the counterweight <NUM>, for example, lifted to the landing <NUM>N+<NUM>.

It should be noted that the "lifting process of the elevator car <NUM>" in this step.

S370 can include multiple sub-processes of sectionally lifting the elevator car <NUM>, and the lifting of the elevator car <NUM> and the operation of reinforcing the mounting of the guide rail <NUM> can be performed at the same time. In an embodiment, after each of the guide rail 930b is reinforced well by the worker <NUM> on the elevator car <NUM>, the lifting assembly may be controlled to lift the elevator car <NUM> with a distance along the well-reinforced guide rail 930b.

In step S380, referring to <FIG>, it is the recovery step after the jumping is completed, which mainly includes the worker <NUM> coming out of the hoistway <NUM>, removing the lifting assembly from the landing, releasing the fixation of the counterweight <NUM>, and the like; elevator car <NUM> may thus travel between the landing <NUM><NUM> and the landing <NUM>N+<NUM> under the drive of the tractor.

Thereto, the jumping process of the jumping elevator system <NUM> is substantially completed. It will be understood that the above jumping process can be repeated, and the embodiment of the jumping elevator system <NUM> shown in <FIG> can also complete a similar jumping process.

The jumping method of the above embodiment especially have one or more of the following advantages:.

It will be appreciated, in connection with the above jumping methods, that embodiment of the jumping elevator system of the present invention have one or more of the following advantages:.
