A lift cage includes a platform having a plurality of platform sections. The cage includes a front-sided and a rear-sided platform section arranged on a central platform section. The platform sections have connection points which are arranged on parallel, vertical planes, whereon the platform sections can be connected together by connection elements. In order to provide additional stabilization for the cage platform, stable platform edge profiles are connected to the uppersides of all platform sections. Subsystems of the lift cage can be premounted in the platform sections. A method for installing a lift wherein a cage platform is prepared in at least two separate platform sections, and the platform sections of the cage platform, which are delivered separately, are connected together by connection elements during installation.

Lift cage and method for the installation of a lift

An elevator has deflecting rollers integrated in the car floor. The supporting and driving means is guided in the car floor through a floor channel. A cover serving as protection covers the supporting and driving means running in and running out at the deflecting roller. The hood-shaped cover can be snapped onto the axle of the deflecting roller.

Elevator

In relation with this mechanism for stopping an elevator car is, for the monitoring of the speed of the elevator car, an overspeed governor provided which works based on the swing lever principle, whereby the movement of the elevator car will be transferred by means of a governor rope to the overspeed governor. The governor rope extends itself over the entire shaft height and will be returned at the lower shaft end by means of a deflection sheave and stretched by means of counterweight as well as guided at the upper shaft end over a pulley of the overspeed governor. The ends of the governor rope are fastened on a release mechanics arranged on the elevator car and such release mechanics operates in an emergency a safety gear arranged on the elevator car. With the overspeed of the elevator car a rope brake is released upwards.

Mechanism for indenting a safety gear for an elevator car

A safety device includes a trigger mechanism for triggering a braking wedges attached to first and second double levers to stop an elevator car. A retaining spring detents with a pin on the first double lever and a tension spring engages either the first double lever or the second double lever. The retaining spring maintains the double levers unactuated during normal operation of the elevator and the spring element actuates the double levers after an actuation of the trigger mechanism by a speed limiter.

Safety device for an elevator

A tripping device for engaging an elevator lift cage safety brake has actuating levers arranged at a rotary axle for engaging safety brake wedges of the safety braking device. Each actuating lever has a longitudinal slot matched to the diameter of the rotary axle, wherein the actuating lever is freely movable in the direction of the rotary axle and in the direction of the length of the actuating lever. A torsion spring fixes the actuating lever about the rotary axle. One spring end presses the actuating lever downwardly, wherein the movement of the actuating lever is limited by a lower abutment. The other spring end is detachably connected to a support. An upper abutment limits the movement of the actuating lever upwardly. The lower abutment and the upper abutment are each held at a respective end of a T-shaped shackle, wherein the shackle is fixedly connected to the rotary axle. The freely movable actuating levers facilitate access to the safety brake wedges of the safety braking device and prevent erroneous tripping.

Equipment for engaging a safety braking device for a lift cage

A safety brake device has a setting device moving an abutment or a housing to limit movement of brake wedges engaging a guide rail which limits a braking force applied by the brake wedges. The setting device can continuously adjust the braking force limit in dependence on a magnitude of a mass to be braked.

Brake arresting device with adaptable brake force for an elevator

A braking device acts on a guide rail and consists of a housing that is arranged at an elevator car yoke and serves as a support for spring packets and/or for adjusting packets. The housing also serves as a support and guide for chock guide elements that in turn retain and guide brake chocks with brake linings. Pushrods engage at one end at the brake chocks, and at the other end are pivotably connected to an actuating fork. Upon braking of the elevator car, the actuating fork is moved at the pushrod end in the direction of the braking device. The guided brake chocks with the brake linings slide in the braking device. At the same time the brake linings are moved at the guide leg of the guide rail. The brake chocks are moved in the braking device and the spring and adjusting packets are stressed, whereby a braking force for stopping an elevator car or a counterweight is generated.

Braking device for an elevator

An improvement for lift equipment having a lift cage and a counterweight movable in a lift shaft with travel buffers at at least one end permits override of safety brake operation when buffer travel occurs. The invention comprises a blocking device which blocks operation of the safety brake, and may include a blocking lever connected to a trip lever mechanism of the safety brake and a blocking element which controls the movement of the blocking lever.
