Abstract: A brake device for braking a traveling body movable along a guide rail in a movement direction includes a holder mounting a brake element that has a brake surface directed toward the guide rail, the brake element being movable relative to the holder between a free-running position and a braking position. A pretensioning element is activated to exert a force that moves the brake element toward the braking position. A release element holds the pretensioning element in a holding state and is activated into a released state to reconfigure the pretensioning element from a deactivated configuration into the activated configuration. A pressing element in an actuated state generates a force on the brake element in a direction toward the guide rail to enable a reset of the brake device.

Abstract: An elevator system has a car assembly including a first elevator car, a second elevator car, a counterweight, and a drive machine unit having a traction sheave and a traction device guided over the traction sheave. The traction device is connected to the car assembly and the counterweight on opposite sides of the traction sheave. An adjustment mechanism enables the second elevator car to be adjusted in relation to the first elevator car within the car assembly. The adjustment mechanism has an adjustment device, a first adjustment traction device and a second adjustment traction device. The first adjustment traction device and the second adjustment traction device are guided over the adjustment device. The first adjustment traction device and the second adjustment traction device are connected to the second elevator car on one side of the adjustment device and to the counterweight on the other side.

Abstract: A brake device for braking an elevator installation traveling body movable along a guide rail includes a holder mounting a brake element having a brake surface movable relative to the holder between a freewheel position and a braking position. In a deactivated configuration, a pretensioning element does not exert any force moving the brake element towards the braking position, and in an activated configuration exerts such force. In a retaining state, a release element retains the pretensioning element in the deactivated configuration, and when activated into a released state, the release element changes the pretensioning element into the activated configuration. In an unactuated state, a friction-generating element does not abut the guide rail and, in an actuated state generates friction by abutting the guide rail to exert a force on the brake element and force the brake element towards the freewheel position.
