Description
The hydraulic safety (emergency) brake is a high-power braking device used on low-speed shafts (drum shafts).
It can be widely used for emergency safety braking on low-speed shafts of large and medium-sized cranes, port handling machinery lifting, and boom pitching mechanisms.
It is also applicable for working braking and emergency safety braking of mine winches, hoists, and high-power inclined belt conveyors, safety braking of cable cars and cable crane drive mechanisms, and safety (emergency) braking on low-speed shafts of lifting mechanisms in special cranes such as casting cranes.
