An elevator system includes a first elevator car, a second elevator car, a drive-machine, and a suspension apparatus that passes over a traction sheave of the drive-machine to cause the cars to travel one above the other in a travel space. The suspension apparatus is divided into a first set and a second set. A displacement mechanism fixed in the travel space interacts with the second set between the traction sheave and the second car to vary the distance between the cars. This distance can be adjusted independent of the traction sheave. The displacement mechanism can have a pulley arrangement with a displaceable pulley displaced by a displacement drive to vary a length of a section of the second set between the displacement mechanism and the second car.

Elevator system

A connecting element connects a first wall panel with a second wall panel. A first spring element is supported on the upper part of the connecting element and on one side of a first bend. A second spring element is supported on the upper part and on one side of a second bend. The other side of the second bend presses on one side of the first bend. The connecting element is introduced without a tool into a first slot of the first bend and the second bend is placed at a second slot over the connecting element.

Equipment for connecting panels of an elevator cage

An elevator cage is movable in an elevator shaft, wherein a ventilating device is fastened to a cage outer surface, wherein this ventilating device forms at least one ventilation channel, wherein the at least one ventilation channel has at least one primary ventilation opening enabling an air exchange between the ventilation channel and the elevator shaft, wherein at least one of the cage outer surfaces has at least one secondary ventilation opening enabling an air exchange between a cage interior space and the at least one ventilation channel, with at least one element of insulating material, and wherein the at least one element substantially determines a path of the at least one ventilation channel.

Device for ventilating an elevator cage

A support frame has at one or more lower cage corners a respective support, at which at least one damping element is arranged. The support has a U-shaped cross-section and can be inserted into a beam with C-shaped cross-section. The elevator cage is mounted on the damping elements, which can keep oscillations and vibrations away from the elevator cage. Near the inserted support, a device can be provided for raising the elevator cage if the support or at least one damping element has to be replaced.

Support frame with damping elements for mounting an elevator cage

An elevator cage floor has a composite-structure or sandwich mode of construction, including at least one base plate, at least one top plate and at least one composite-structure core disposed therebetween and having at least two chambers, wherein the composite-structure core is connected with the base plate and the top plate. At least one of the at least two chambers of the composite-structure core is at least partly filled with a defined amount of a filler.

Elevator cage floor with filler

A floor for an elevator cage has a base plate, a top plate and a support structure arranged therebetween. The support structure comprises a grating arrangement including a plurality of intersecting profile members standing on edge. For local reinforcement, the support structure additionally includes a second grating arrangement superimposed on the first arrangement.

Floor for an elevator cage

An elevator installation includes an elevator cage with a support construction carrying the elevator cage, wherein the support construction has two beams. Mounted on each beam is a positioning arrangement on which, for example, a sensor is positioned, which is part of a load measuring device, wherein the positioning arrangements have material structures or sensor carriers. The sensors detect a change in spacing of the material structures or of the sensor carriers from one another, wherein this change in spacing is caused by a change in loading of the elevator cage. Signals of the sensors are processed in an evaluating unit and a signal representing the loading is used in an elevator control.

Load measuring device for an elevator installation

A multi-stage elevator car has equipment for fine positioning of the cars wherein the car thresholds are positionable at the level of the floor thresholds. The fine positioning adjusting equipment operates on the principle of a double lever and moves a car frame along a path (&#x394;z).

Equipment for fine positioning of a car of a multi-stage car

A multi-stage elevator car has equipment for fine positioning of the cars wherein the car thresholds are positionable at the level of the floor thresholds. Adjusting equipment operating on the principle of a differential block and pulley is provided for fine positioning of the cars, the equipment including an endless cable guided over deflecting rollers arranged at the main frame of the multi-stage car and over deflecting rollers arranged at the cars, wherein the cars execute vertical movements of opposite sense.
