Brake for rockfall protecting net

摘要

A brake for a rockfall protection net includes a housing, at least three rolling shafts, and a metallic deformed plate. Force exerting sections of the rolling shafts are movably arranged in the housing and parallel with each other. At least one rolling shaft is not located on a same plane where the other rolling shafts are located. A first end of the metallic deformed plate penetrates into the housing from a back end of the housing and stretches out from a front end of the housing. A deformed section of the metallic deformed plate is located in the housing. The force exerting sections of al least two rolling shafts contact a first surface A of the metallic deformed plate, and the force exerting section of at least one rolling shaft contacts a second surface B of the metallic deformed plate.
