Abstract
Device for the emergency lowering of a load carrying means for a stacker truck, in particular a reach-type forklift truck, with a valve arrangement accommodated in a valve block, via which the inflow and outflow of a hydraulic means is regulated to and from a lift cylinder for the load carrying means, with a bypass between the lift cylinder and a tank, with a barrier element in the bypass. The barrier element is screwed into a threaded bore of the valve block and, in the fully screwed-in position, closes off the bypass branch. One end of a cable transmitting a torque is rotationally fixedly connected to the barrier element and the other end of the cable has a handle for turning the cable.
