Rail Clamps - Guided

GRC Guided Rail Clamps are spring set and hydraulically released storm brakes. They use mechanical advantage of a toggle style mechanism to push the leavers. Levers with serrated shoes apply to the sides of a crane rail thus providing a friction forces which prevent a crane from uncontrolled moving along the rails in case of sudden bursts (micro burst) of wind.
BRELX Rail Clamp mechanism design allows for its weight to be distributed to two hardened, low friction plain rollers without flanges. The weight is additionally distributed to four low friction bearings guided on two channel bars at the top of the rail clamp mechanism. This allows the mechanism to float vertically and horizontally with ease. For horizontal float, we supply hardened rail guides that attach to the guide roller frame. Because our clamp mechanism floats laterally with very little friction there should be a minimum rail guide wear and no chance for rail clamp shoes to hit the rail during crane traverse.
Unique but simple design eliminates expensive replacement of profiled guide wheels with worn-out flanges and ensures that rail clamp shoes are protected from damage. This reduces the maintenance costs and increases rail clamp reliability. 
Available GRC models with holding capacities: from 50kN to 600kN.
