YP Fail-Safe Power-Off Disc Brake, Instant Lock To Resist Strong Wind For Outdoor Port Container Gantry Cranes

YP Fail-Safe Power-Off Disc Brake

YP series spring-applied electro-hydraulic disc brake is specially designed for large outdoor port equipment such as container gantry cranes, yard trolleys and ship unloaders. Different from traditional drum brakes, disc structure delivers outstanding heat dissipation and consistent braking torque. It adopts standard fail-safe design: once power is disconnected, powerful compression springs push friction pads to clamp the brake disc instantly, providing ultra-reliable wind-resistant holding performance to avoid trolley drifting under strong coastal winds.

Core Competitive Advantages

• Instant power-off locking & reliable windproof performance (Core Highlight)
• Preloaded heavy-duty braking springs trigger full clamping within 0.3–0.4 seconds after power loss. High static holding torque firmly locks the wheel set of container gantry cranes, effectively counteracting crosswinds at open-air ports. Eliminate major safety hazards like trolley sliding, container tilting and track collision during shutdown or power outages.
• Excellent heat dissipation, no thermal fade under high-frequency continuous braking
• Open disc structure dissipates heat rapidly during repeated deceleration and long-hour operation. Braking torque will not decline due to overheating, perfectly matching high-duty cycle working conditions of port container loading/unloading. Stable braking effect prolongs service life of friction pads.
• Built-in automatic pad wear compensation mechanism
• The linkage structure automatically compensates clearance as friction pads wear down. No frequent manual gap adjustment required, always maintain stable braking distance and holding force, greatly cutting daily maintenance workload for port equipment teams.
• Low-maintenance modular structure
• All swing pivots adopt maintenance-free self-lubricating bearings, periodic greasing is unnecessary;
• Snap-in quick-change friction pads, replaceable without disassembling the whole brake body to save repair time;
• Visible graduated scale on the spring tube supports stepless torque adjustment to adapt different container loads.
• Diversified matching & customizable configurationsStandard matched with ED series electro-hydraulic thrusters; BEd flameproof thruster options available for chemical plants and underground mining hazardous zones. Optional accessories include manual emergency release lever, dual status monitoring limit switches for PLC safety interlock, IP65 dust & rainproof housing, anti-corrosion coating for coastal salt fog environments. Vertical and horizontal installation modes support various gantry crane layout demands.
