Safety Disc Brakes .

Fail-safe (storm) disc brakes — spring-applied, hydraulically released. Clamping force generated by Belleville spring stacks; release by hydraulic power unit. On power loss or pressure drop the brake closes automatically — designed as emergency stop for hoists, skip winders, ship loaders and heavy-duty cranes. Available for 500 / 630 / 800 / 1000 mm discs, compatible with standard constant-pressure and pulse HPUs. Options: state limit switches, manual release, corrosion-resistant and explosion-proof variants.
