Patent DE-2441122-A1 (DE)
Title: Rail-clamping brake to hold travelling crane stable in high wind - has folding wedges which tighten brake as wind rises(NL-2.3.76)
Inventor: GOLDBAUM HARTMUT
IPC: B66C9/18
Filed: 1974-08-28
Abstract: Hydraulic cylinders and pistons act on the upper ends of levers to apply or release the brake. The lower ends of the levers are at the level where wedges exert the braking force on the sides of the rail. The wedges of each folding pair are groove together, so that their slant edges remain in contact, thus, when the lower ends of the vertical levers move towards each other, overcoming the spring, the wedges move along their slant edges away from the rail, releasing the brake. If, in a high wind, the spring braking should provide insufficient, the incipient movement of the crane causes the folding wedges on the windward side to exert a countervailing clamping action on the rail.
