Manually operated storm brake / rail clamp to protect crane systems or railbound machines against unwanted movements e.g. storm.
MP version (manual positioner):
The clamp jaws are lifted above the top of the rail when the clamp is opened, so there is no risk of collision for the clamp jaws
RF version (roller guide):
The clamp jaws are lifted above the top of the rail when the clamp is opened, so there is no risk of collision for the clamp jaws.
However, the roller guide stays in the positions to the side of the rail head and is at risk of collision.
