Abstract
Spring brake for an industrial truck with a brake disc, which is splinedly mounted on a rotatable motor shaft, a brake magnet disposed in a vehicle-fixed brake housing, a splined axially movable pressure plate between brake disc and brake magnet, which is pie-tensioned against the brake disc by a spring arrangement, and a device for monitoring the switch status of the spring brake, characterised in that a proximity switch is fixed on the brake housing, an initiator for the proximity switch is connected with the pressure plate and the hysteresis for the proximity switch is smaller than the minimal travel path of the pressure plate.
