Core Competitive Advantages
Self-locking wedge rail clamping, top-tier anti-typhoon performance (Core Highlight)
Special inclined wedge mechanical self-locking principle can amplify clamping force exponentially. Once wedge contacts rail surface, it forms stable mechanical lock without continuous hydraulic thrust support. It can reliably lock crane tracks under level 10–12 strong coastal typhoons, solving the biggest safety hidden danger of unattended open-air port equipment parking.
Power-off automatic clamping fail-safe design
When power supply fails, circuit trips or equipment emergency stops, built-in reset spring automatically drives wedge to clamp the steel rail within short response time. No manual operation needed, realize passive windproof protection for unmanned container yards day and night. Optional travel limit switches feed back wedge open/closed signals to PLC to form full equipment safety interlock chain.
Wear-resistant alloy wedge friction blocks, long service life
High-hardness alloy friction contact blocks have strong wear resistance, anti-slip texture to increase friction coefficient with steel rail. Resist long-term reciprocating contact friction and coastal salt fog corrosion, reduce frequent replacement frequency and lower port operation spare parts cost.
IP65 all-weather anti-corrosion structure for coastal ports
Whole brake frame adopts thick cast steel with heavy-duty anti-rust salt-fog coating; sliding guide parts add dust and rainproof cover, adapt long-term outdoor high-humidity, high-salt, strong wind port environment, no rust jamming failure.
Low maintenance modular design
All sliding guide hinges equipped with maintenance-free self-lubricating bearings, reduce regular grease maintenance;
Wedge friction blocks adopt plug-in quick replacement structure, no need to disassemble the whole brake body;
Universal matching ED series electro-hydraulic thrusters, spare parts easy to purchase and replace;
Visible adjustment scale for wedge gap, convenient on-site calibration for different rail specifications.
Diversified customization options
Complete model range YFX-350/YFX-500/YFX-700 to match different tonnage rail cranes. Explosion-proof versions with BEd flameproof thrusters optional for chemical and mining hazardous rail equipment. Custom mounting brackets adapt various rail sizes and crane undercarriage layout.
