SB/SBDSB, SBD Series Safety Brakes
Hydraulic Safety (Emergency) Brakes HUAWU SB/SBD
SB and SBD are normally closed hydraulic emergency brakes for the low-speed (drum) shaft: clamped by disc spring packs and released by pressure from an SBH or YZBS hydraulic power unit. The SB series has 6 sizes with clamping force 50–400 kN for discs from 500 mm; SBD comes in versions A (100–315 kN, discs 800–1,800 mm), B (80 and 160 kN), C (250–425 kN, discs from 1,800 mm) and D (80–240 kN, discs from 600 mm); B and C replace the former SBB. Non-asbestos linings with a friction coefficient of 0.4 are insensitive to water and salt spray. Options: release, close and lining wear limit switches.
