An elevator system and a multi-deck car for an elevator system. The elevator system has a multi-deck car that moves up and down along an elevator guide rail in an elevator shaft and comprises a first car and a second car connected to and located below the first car, wherein the second car is provided with a stop-support device configured to be operably engaged with a mating device mounted at a pre-set position on the elevator guide rail and/or the inner wall of the elevator shaft, for stopping and supporting the multi-deck car at the pre-set position upon engaging of the stop-support device and the mating device. The invention not only has advantages of quick and convenient operation, but also can effectively ensure the safety of both elevator equipment and field workers.

The present application relates to the technical field of lifting equipment, and provides a traction machine and a lifting equipment. The traction machine includes traction pulleys, traction ropes driven by the traction pulleys and fixed pulleys for changing directions of the traction ropes. The fixed pulley is provided with a sensor sensing member rotating with the fixed pulley, a traction machine sensor is arranged beside the fixed pulley; the traction machine sensor is configured to detect a rotation speed of the sensor sensing member, and send the rotation speed to a controller of the traction machine; the controller controls a rotation of the traction pulley according to detected data of the traction machine sensor. Since this kind of traction machine is provided with the sensor sensing member and the traction machine sensor, it is capable of detecting whether the traction machine has an abnormal operation, and stopping the traction machine immediately in an abnormal state.

The present invention concerns an elevator comprising: an elevator shaft defined by surrounding walls and top and bottom end terminals; an elevator car vertically movable in the elevator shaft; an elevator hoisting machinery adapted to drive an elevator car; an electromechanical braking apparatus configured to brake movement of the elevator car; a first measuring device adapted to provide first position data and first speed data of the elevator car; a second measuring device adapted to provide at least a second position data of the elevator car; and a safety monitoring unit communicatively connected to the first measuring device and the second measuring device and configured to determine a synchronized position of the elevator car from the first and the second position data, and to determine an elevator car slowdown failure in the proximity of the top or the bottom end terminal from the first speed data and from the synchronized position of the elevator car. The safety monitoring unit is adapted to cause braking of the elevator car with the electromechanical braking apparatus upon determination of the slowdown failure.

In an elevator apparatus, an abnormal acceleration detecting mechanism detects abnormal acceleration of an ascending/descending body due to breakage of a suspending body, and activates a safety device. The abnormal acceleration detecting mechanism includes: an inertia sheave that is rotatable around a sheave shaft independently from an interlocking sheave; a pawl that is connected to the interlocking sheave and the inertia sheave, and that is displaceable between a normal position, and an activating position that displaces a movable shoe to a gripping position; and an elastic body that holds the pawl in the normal position by applying an initial pressure, and that also rotates the inertia sheave together with the interlocking sheave.

A buffer device (121) for an elevator system (100), the buffer device (121) including a first contact structure (501) and a second contact structure (503). The first contact structure (501) includes a first contact surface (505), and the second contact structure (503) includes a second contact surface (507). The first contact surface (505) and the second contact surface (507) are arranged for contacting respective vertically offset surfaces of an elevator car (101) or counterweight (109).

An elevator system comprising an elevator cabin, and a traction wire rope for driving the elevator cabin and/or a safety wire rope, wherein the elevator system further comprises an upper transverse element provided above the elevator cabin and adapted to be guided along the traction wire rope and/or the safety wire rope, and a support structure which is adapted to support the upper transverse element and substantially impede its movement in a downwards direction and in a horizontal direction, and to allow movement of the upper transverse element in an upwards direction.

An illustrative elevator system includes an elevator car, a machine including a motor that provides a motive force for moving the elevator car along a travel path and a brake that resists movement of the elevator car, and a brake controller. The brake controller is configured to determine when the elevator car is within a selected range of at least one end of the travel path. The brake controller inhibits a delay in application of the brake when the elevator car is within the selected range and permits a delay in application of the brake when the elevator car is outside of the selected range.

Elevator toe guard assemblies are provided. The elevator toe guard assemblies include an elevator car frame, a buffer located within an elevator shaft, and a toe guard mounted to the elevator car frame. The toe guard has a first state being a fully extended state, a second state wherein the toe guard does not contact a pit floor during operation of an elevator car, and a third state wherein at least a portion of the toe guard is moved relative to the elevator car frame during an impact between the buffer and the pit floor.
