Abstract:
1. An elevator, comprising: an elevator car; a set of hoisting ropes; a traction sheave; a compensating device; a stopper; and a gripping element; wherein the set of hoisting ropes comprises one rope or a number of parallel ropes, wherein the elevator car is supported by the set of hoisting ropes, wherein the traction sheave moves the elevator car using the set of hoisting ropes, wherein the elevator includes rope portions of the set of hoisting ropes going upwards from the elevator car, wherein the elevator includes rope portions of the set of hoisting ropes going downwards from the elevator car, wherein a rope portion going from the traction sheave in a direction of the rope portions going upwards from the elevator car is under a first rope tension (T wherein a rope portion going from the traction sheave in a direction of the rope portions going downwards from the elevator car is under a second rope tension (T wherein the compensating device is adapted to do one or more of the following: wherein the stopper is provided on the elevator car, wherein the gripping element comprises at least a first part and a second part, said first part includes a diverting pulley, wherein said set of hoisting ropes is positioned between said gripping element and said diverting pulley of the first part wherein said first part is movably mounted with respect to said second part wherein when the stopper meets the first part, said first part is moved toward said second part to grip said set of hoisting ropes to prevent, stop, or prevent and stop motion of the elevator car, and wherein when the elevator car is set in motion in the upward direction and reaches an area where the motion of the elevator car has to be stopped, the gripping element stops the motion of the hoisting ropes, whose one end is connected to a diverting pulley of the compensating device, whereby via a gripping action of the gripping element, the compensating device is non-operational such that the first rope tension (T when the elevator car is set in motion in the downward direction, the gripping element releases the hoisting ropes and the compensating device is again operational.
