TP Series Disc Brake Technical Specifications
1. Overview
The TP series spring-applied, hydraulically released disc brakes provide failsafe braking for heavy machinery including mine hoists and port cranes. Compliant with GB/T 3811-2008 and AQ 1036-2007 standards, they deliver up to 3,000 kN·m braking torque with ≤0.3s response time.
2. Structural Components
Brake Disc: 65Mn/42CrMo alloy steel (HRC45-50), Ø800-2500mm
Brake Caliper: Asbestos-free pads (μ≥0.35), disc spring assembly
Hydraulic Station: 4-6MPa working pressure with proportional valve
