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.

The invention relates to a support apparatus for an elevator car. The support apparatus comprises a support block for attaching to a sidewall of an elevator hoistway, the support block having an oblique surface. The support apparatus also comprises a sliding plate for mounting to the elevator car. The sliding plate is movable between an extended position and a retracted position. The sliding plate has an oblique surface facing the oblique surface of the support block when the sliding plate is in the extended position. The sliding plate is slideable over the oblique surface of the support block when being moved from the extended position to the retracted position. The support apparatus also comprises an actuator shaft attached to the sliding plate and an actuator configured to move the sliding plate using the actuator shaft from the extended position to the retracted position. The actuator is attachable to the elevator car.

A damper for elevator, and an elevator, that enable reduction of the maximum deceleration of a lifting/lowering body by suppressing deformation of a foamed body for absorbing impact. The damper for elevator includes: urethane foam having a collision surface with which a lifting/lowering body is to collide; and an outer peripheral member attached to the outer side of the side-part surface of the urethane foam and having an inner side surface bowed outward, wherein impact by collision of the lifting/lowering body is buffered by deformations of the urethane foam and the outer peripheral member.

An elevator device including on-car presence detection units, each being configured to detect presence of a person on top of a corresponding one of cars, on-car operation panels, each to be operated for a manual operation of the corresponding one of cars, and an elevator control device including a car operation approval unit configured to approve or cancel the operation on the on-car operation panels. When the on-car presence detection units have detected the presence of persons on top of the plurality of cars, the operation on the on-car operation panels of all the cars is canceled by the car operation approval unit. When the on-car presence detection unit has detected the presence of a person on top of one of the plurality of cars, the car operation approval unit approves the operation on the on-car operation panel of any one of the plurality of cars.

A shaft hoisting plant has a conveyance and an overwind brake device for the conveyance, a travel path for the conveyance, and an overwind path adjoining a lower and/or upper end of the travel path. The overwind brake device includes retaining bars arranged in pairs in a manner spaced apart from one another and extending in a longitudinal direction, energy-absorbing material arranged in the form of plates arranged one above another in the longitudinal direction between the retaining bars. A plow is movable relative to the retaining elements, such that, upon overwinding of the conveyance, the plow deforms and/or destroys the energy-absorbing material between the retaining elements.

An elevator buffer system includes a buffer (44), a frame (30) spaced above the buffer, a platform (48) spaced above the frame, and a pre-compressed pad device (52) disposed between the frame and the platform and engaged to one of the frame and the platform. The system is constructed to move between a non-strike position, where the pre-compressed pad device is spaced from the other of the frame and the platform; a mid-strike position, where the pre-compressed pad device is in contact with the other of the frame and the platform; and a full-strike position, where the pre-compressed pad device is further compressed against the other of the frame and the platform.

A hoist system for hoisting a conveyance from a mineshaft, comprising: a head frame mounted over the mineshaft; a hoist connected to the conveyance by an elongate flexible hoisting element so as to be operable to hoist the conveyance from the mineshaft by winding the hoisting element; an upper crash barrier located on the head frame so as to be engageable by the conveyance to prevent upward movement of the conveyance beyond the crash barrier in an overwind condition; and an upper conveyance retarder to retard upward movement of the conveyance as it approaches the crash barrier.
