Elevator systems and methods of operation include a tension member support positioned within an elevator shaft, a tension member suspended from the tension member support within the elevator shaft, and a slack detection system. The slack detection system includes at least one biasing element housed within the tension member support and operably coupled to the tension member, the at least one biasing element arranged to receive a load from the tension member and a switch arranged to be moved from a first position to a second position in response to movement of the at least one biasing element, wherein when in the second position the switch triggers an emergency stop of an elevator car within the elevator shaft.

Elevator, which includes at least an elevator car and a device for moving the elevator car, preferably along guide rails, and a counterweight, and one or more ropes, which rope connects the elevator car and the counterweight and is separate from the supporting function and passes around a diverting pulley mounted on the bottom end of the elevator hoistway. The rope comprises a power transmission part or a plurality of power transmission parts, for transmitting power in the longitudinal direction of the rope, which power transmission part is essentially fully of non-metallic material.

A safety gear system for an elevator has a main static mass, an auxiliary static mass and a dynamically changing mass, wherein the dynamically changing mass changes in accordance with the travel of the main static mass. The safety gear system includes at least one first safety gear which is configured to brake the auxiliary static mass by a constant braking force, and at least one second safety gear which is configured to brake the main static mass and the dynamically changing mass by an adjustable brake force which is adjustable in accordance with the change of the dynamically changing mass.

A counterweight slack detection switch including a body, a first belt guide mounted to the body and configured to engage a first side of a tension member, a second belt guide mounted to the body and configured to engage the first side of the tension member, a lever arm having a first end and a second end, the first end pivotally mounted to the body, a deflectable member biasing the lever arm relative to the body, a third belt guide mounted to the second end of the lever arm and configured to bias the tension member from a tension position to a slack position, and a switch mounted to the body and configured to contact the tension member when the tension member is in at least one of the tension position and the slack position.

A guide device and an elevator system are provided by the present application. The guide device is configured to guide a compensation chain of an elevator system and includes: a fixed mechanism, which is configured to install to an elevator hoistway, for example a stationary object such as a hoistway wall, a rail or a pit ground, and provide support for the guide device; and a guide mechanism connected to the fixed mechanism; wherein in a state where the guide mechanism is subjected to an external force exceeding a preset value, the guide mechanism is capable of reciprocating in a vertical direction relative to the fixed mechanism.

A force application assembly, an elevator and a method of elevator rescue. The force application assembly is provided for applying a force to an elevator car when the elevator car and a counterweight are in a balanced state, and the force application assembly includes: a first attachment portion, which is configured to be removably attached to an elevator hoistway; a second attachment portion, one end of which is removably fixed relative to the elevator car or the counterweight, and which is configured to be at least partially elastic; an actuation portion connected between the first attachment portion and the second attachment portion, wherein the first attachment portion is configured to be fixed relative to the actuation portion, and the second attachment portion is configured to be movable relative to the actuation portion; and an operation portion, which is associated with the actuation portion.

A damping device for a main rope suspending a car of an elevator includes a coupled, a first pulley and a drive. The coupler is attached to the main rope above the car, and is configured to be pulled, in response to vibrations of the main rope, with a damping rope so as to suppress vibrations of the main rope. The first pulley is supported at a same height as a height of the coupler. The drive is configured to suppress vibration of the main rope by pulling a first damping rope coupled to the coupler and passing over the first pulley.

An elevator includes a compensating sheave, a compensating rope, a guide, a holder, a driver, a lateral vibration detector, and driver controller. The compensating rope is looped around the compensating sheave to be bent back upward in a hoistway, and has a first end connected to a car and a second end connected a counterweight, the compensating rope suspended from the car and the counterweight. The guide guides the compensating sheave in a vertically displaceable manner. The holder holds the guide to be displaceable in a horizontal direction. The driver drives the holder in the horizontal direction. The lateral vibration detector detects lateral vibration of the compensating rope. The driver controller controls the driver based on a result of detection by the lateral vibration detector and accordingly drive the holder in the horizontal direction so as to dampen lateral vibration of the compensating rope.

The invention relates to a rope anchor for anchoring one or more ropes of an elevator, comprising at least a wedge housing comprising a tapering nest shaped to have a narrow end which is open towards a first direction, and a wide end which is open towards a second direction; and one or more wedge members mounted in the tapering nest for being wedged against a rope passing through the tapering nest; and one or more spring members for urging and/or arranged to urge the one or more wedge member towards the narrow end of the tapering nest; and a releasing mechanism actuatable to move the one or more wedge members (2,3) towards the wide end of the tapering nest. The invention also relates to an elevator arrangement comprising said anchor, as well as to a method implementing the arrangement.

An elevator assembly includes an elevator cabin, a counterweight, a compensating cable and a means for suspending the compensating cable from the elevator cabin. The compensating cable includes a proximal end and a distal end. The proximal end is coupled with the elevator cabin and the distal end is coupled with the counterweight. The means for suspending the compensating cable is coupled with the elevator cabin and is further coupled with the compensating cable adjacent the proximal end of the compensating cable. The compensating cable has an elastic deformation limit. The means for suspending the compensating cable has a tensile strength that is less than the elastic deformation limit of the compensating cable.
