ABSTRACT:
A fall brake for material in which a plurality of frames are suspended one beneath the other, each frame holding a material guide. The frames are pivotally interconnected in staggered positions and the lowermost frame is suspended to a lifting mechanism through a flexible member. In order to prevent the risk of damage in the case of shocks and to provide a small height of the fall brake in the lifted position, the lowermost frame can be upwardly pivoted from its operative position into an inoperative position, in which the frame is mainly parallel to the overlying frame, each frame having suspended to it a material guide being at an angle to said frame.
