Core Competitive Advantages
Air-loss automatic locking & excellent windproof performance (Core Selling Point)
High-strength pre-compression springs provide large static braking torque. When air supply is interrupted unexpectedly, the brake instantly clamps the brake disc without delay. Firmly lock the wheel sets of rubber-tyred gantry cranes and stop the reverse sliding of inclined belt conveyors, effectively resisting strong crosswinds in open-air port yards. Avoid equipment collision, cargo tipping and material backflow during unattended parking.
Outstanding heat dissipation, no thermal fading under frequent braking
Open exposed disc design quickly dissipates heat generated during repeated deceleration and long-hour operation. Braking torque will not decline due to overheating, perfectly matching high-duty-cycle loading/unloading work of port RTG and continuous running of mining conveyors. Stable clamping force greatly extends brake pad service life.
Oil-free pneumatic drive, zero hydraulic leakage faults
Cylinder-driven structure without hydraulic oil, completely get rid of common problems of electro-hydraulic brakes such as oil leakage, seal aging and oil deterioration. No regular oil replacement or sealing maintenance, greatly reduce long-term operation and maintenance costs for port and mining workshops.
Automatic pad wear compensation structureBuilt-in compensation mechanism automatically adjusts clearance as friction pads wear down. No frequent manual gap calibration required, always maintain consistent braking distance and stable holding force, lower daily maintenance workload of equipment teams.
Low-maintenance modular design
All swing hinge points adopt maintenance-free self-lubricating bearings, regular greasing is not needed;
Snap-in quick-replace brake pads, can be replaced without disassembling the entire brake body, saving more than 60% maintenance time;
Torque adjustable via spring preload, adapt different container loads, wind resistance and conveyor material weight demands.
