Full Description:
FIELD 
     The present embodiments generally relate to remotely controlled equipment that removes and installs withdrawable motor control center components. 
     BACKGROUND 
     A need exists for a rollable, repositionable tool that prevents harm to humans in a facility which has electrical equipment that needs replacing and is susceptible to arcing during testing, maintenance or switching out of equipment on a piece by piece basis. 
     A need exists for a tool that can be remotely operated by a human and used for performing maintenance or switching out of equipment such as in a circuit breaker room on a piece by piece basis without shutting down power to the entire facility. A need not to shut down a hospital is particularly important for hospitals, but also has an impact on other facilities, such as hotels which have 24 hour, 7 day a week occupation by at least one resident. 
     It is common for a large facility, such as a hospital or a hotel, to have to shut down all power in the facility for 1 and ½ hours to replace circuit breakers and do other manual electrical maintenance in a switching room. Typically, a hotel has to shut off power, typically between 3:00 am and 4:30 am at least once a year to replace used or worn equipment. A hotel often has pilots staying with them, and these customers, who typically need to be up at 4:00 am, will not stay at the hotel that night, causing a loss of revenue. In a time of recession, loss of customers is to be avoided, and a need has existed for a device to replace this equipment without shutting down the facility. 
     More importantly, hospitals that need to perform the same shut down and prevent arcing in their switch rooms, do not desire a total shut down even for 1 hour. A hospital prefers to stay “on line,” that is, fully powered, otherwise it needs to provide back up power to its emergency room, life support facilities, and intensive care units, where patients are on breathing machines. The time of shut down, scheduling, and costs involved are large, and if something goes wrong it can mean loss of a patient&#39;s life. 
     If no shut down is performed, and the equipment is worked on by hand, the switching room can generate “arcs” of electricity that can cause first and second degree burns to an operator manually swapping out or otherwise working on the equipment. 
     A need has existed for a tool that can be operated remotely by a human that is low cost and prevents the shut down of a facility to swap out circuit breakers or similar “electric arc” producing equipment. 
     The present embodiments meet these needs.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Before explaining the present system in detail, it is to be understood that the system is not limited to the particular embodiments and can be practiced or carried out in various ways. 
     The present embodiments relate to a remotely operated tool termed herein “a bucket extractor” for removing equipment in a facility, such as removing circuit breakers or other withdrawable electrical apparatus, such as those commonly found in a switch room of a hospital. 
     The moveably, relocatable tool enables an operator to no longer need to wear the typical inch thick full body arc flash hazard suit when operating the tool. 
     The tool allows an owner to more easily maintain equipment in an electric room, clean it up and lube it up, without needing to shut down the entire facility during such maintenance because there is a remote-control for operating the tool. 
     The invention can be operated by a user without detailed training. An unskilled worker can use this tool in less than 1 hour from seeing the tool for the first time. 
     The tool enables a wide variety of plant personnel, trained and untrained, to perform the maintenance function safely. 
     The embodiments can prevent explosions and arcing fires of electricity from reaching a person, as the operator, because the operator can be in a different room while the tool is operating. 
     This tool is easy to move, enabling men and women, strong or frail, to move, install, and remotely operate the device. 
     The equipment prevents an arc explosion from harming people during live switching, live switch testing, or live maintenance of electric equipment. This device allows one circuit breaker to be shut down and replaced while an entire bus of circuit breakers remains live and operational. 
     This tool can roll up and down stairs easily for use in many places in a facility. 
     The tool is extraordinarily effective in saving time and money during maintenance, as no power shut down is needed. 
     The tool saves humans from harm, by enabling operation of the device from a safe distance away from the circuit breakers or similar electrical equipment devices. 
     The invention includes in an embodiment a first riser and a second riser extending from a base support. The base support provides a first load-supporting wheel and a second load-supporting wheel. 
     The tool can use at least one floor lock to prevent movement of the base support. 
     A high-lift support rail is fixed to a first and second high-lift rail bracket connected between the first and second risers. 
     A first high-lift support rail bracket and a second high-lift support rail bracket are connected between the first and second risers for supporting the high-lift support rail. 
     A first high-lift moveable slide is connected to the first high-lift support rail and a second high-lift moveable slide is connected to the first high-lift support rail. 
     A moveable high-lift rail is connected to the first and second high-lift moveable slides. A first moveable slide engages the moveable high-lift rail and a second moveable slide is connected to the moveable high-lift rail. 
     A moveable mounting brace with at least one moveable magnetic pad is installed on the bucket extractor tool for engaging a metal surface proximate to electrical equipment of interest. The moveable mounting brace is telescopically connected to the second moveable slide. 
     A linear actuator with a detachable push-pull unit engages electrical equipment of interest for removing or inserting a portion of the electrical equipment while adjacent electrical equipment is operating with a voltage. The linear actuator is connected to the first moveable slide. 
     A remote-switch operator connected to the linear actuator remotely controls and powers the linear actuator. 
     The tool is made up of a first riser and a second riser extending from a base support. 
     The first and second risers can be rounded tubulars connected to the base support in a “U” shape. 
     The base support can be made from plate steel that is reinforced. The base support engages a first load-supporting wheel and a second load-supporting wheel. The load-supporting wheels can be rubberized, electric isolating wheels on rigid wheel centers. 
     To the base support, can be attached at least one floor lock to prevent movement of the base support. The floor lock can be foot operated pedal designs which provide a suction type connection to concrete or smooth floor, or can be another type of foot lock that locks the load-supporting wheels and prevents them from turning, enabling the device to be stable. 
     A high-lift support rail is fixed to and connected between the first and second risers. The high-lift support rail can be made of aluminum. The high-lift support rail, in an embodiment, is centered between the first and second riser using a first horizontal brace at about a 90 degree angle to the high-lift support rail that engages the first and second riser on each end. The horizontal brace for the high-lift support rail can be mounted over the braces used between the first and second risers to provide a sturdy frame to the tool. 
     The moveable high-lift rail is connected in parallel to the high-lift support rail in a sliding engagement that can be raised or lowered and fixed into place, and then moved again. The moveably high-lift rail can create a telescoping effect adjacent the high-lift support rail. 
     The moveable mounting brace operates at about a 90 degree angle to the moveable high-lift rail. The brace is secured on one end to the moveable high-lift rail and on the other end has at least one moveable magnetic pad for engaging a metal surface proximate to electrical equipment of interest. The brace can have two moveable magnetic pads that move in and out of a housing, in an embodiment. Other versions of the moveable magnetic pads are also contemplated herein. 
     Parallel to the moveable mounting brace is the linear actuator with a detachable one push-pull unit for engaging electrical equipment of interest and removing or inserting a portion of the electrical equipment while adjacent electrical equipment is operating with a voltage. 
     The linear actuator has a motor and can be a variable speed motor adapted to run on about 110 volt current or on about a 12 volt DC current. 
     A remote operated switch is mounted between the risers and is connected to the linear actuator for remotely controlling and powering the linear actuator while distanced from possible arc flashing during equipment removal, installation or maintenance. 
     A holding basket can be used between the risers and even extending from the risers opposite the linear actuator for supporting the remote operated switch that powers the linear actuator. The basket can be made of steel, such as ¼ diameter solid tubular steel. 
     The high-lift support rail can be between about 6 feet to about 12 feet in length. The high-lift rail can have the same length, but twice the width of the high-lift support rail. The high-lift support rail and the high-lift rail can be configured to both be made from a generally hollow, lightweight, strong aluminum alloy. 
     The high-lift support rail in an embodiment has a first and second high-lift slider slidably connected to the high-lift support rail for moveably and fixedly supporting the high-lift rail. These devices are generally rectangular and act as a stop as well as a support for the sliding high-lift rail. 
     The high-lift rail in an embodiment has a first channel about 1 inch in depth and a second channel having the same depth parallel to the first channel in the same rail. 
     A front axle in an embodiment is connected to the base support and a first front wheel is on one end of the axle and a second front wheel is on the other end of the axes. This gives a 4 point support to the risers and linear actuator for good stability with no rocking, no vibration, and a rigid stance for insertion of the electrical equipment or removal of the electrical equipment and dealing with the weight of the electrical equipment by the tool. 
     It can be noted that in an embodiment the first and second front wheels have a diameter less than about 25 percent the diameter of the load-supporting wheels. 
     A power supply mount can be positioned and fastened, such as with bolts or similar fasteners, or even welded, between the first and second risers on at least one brace for supporting an AC/DC power supply at least engagaeble with about 110 volts of AC current from a power grid. 
     An embodiment can contemplates that a quick-disconnect can be used with the linear actuator to quickly install and replace push-pull units having different shapes, different features as needed. 
     At least two high-lift stops are mounted to the high-lift rail to prevent excessive movement of the high-lift rail in an embodiment.
