SBDSB, SBD Series Safety Brakes
Hydraulic Safety (Emergency) Brakes ZHONGHAI SBD
Normally closed hydraulic safety (emergency) brakes for the low-speed shaft, i.e. the drum shaft: clamped by disc spring packs, released by pressure from a hydraulic power unit. SB comes in 7 sizes with clamping force 50–500 kN for discs from 500 mm; SBD-A (100–315 kN, discs 800–1,800 mm), SBD-B (80 and 160 kN), SBD-C (250–425 kN, discs from 1,800 mm), SBD-D (50–240 kN, discs from 600 mm) and SBD-DY (100–250 kN) with an integrated 550 W motor, hydraulic system and control. Non-asbestos linings, release, close and lining wear limit switches; requirements to JB/T 10917-2008.
