The WC3J(A) is a 3 ton underground hauler built for medium-scale mining operations requiring reliable material transport in confined spaces. This flameproof mining vehicle features a 48kW ZL495DZLDFB diesel engine with turbocharging and intercooling, delivering consistent power for demanding underground conditions. The robust 510L high-strength steel frame ensures structural integrity under heavy loads, while the fail-safe wet brake system provides automatic engagement upon pressure loss. Its compact dimensions allow efficient navigation of narrow tunnels and low-clearance roadways.
Advanced Flameproof Engine: Equipped with a ZL495DZLDFB diesel engine (48kW output) that meets China Phase III standards, featuring turbocharged intercooling and high-pressure common rail injection for efficient and compliant performance.
Fail-Safe Wet Brake System: Employs a pressure-loss protection wet brake system that integrates service, parking, and emergency braking. It automatically engages upon pressure loss, ensuring ultimate safety and reliability.
Robust Chassis Construction: The frame is manufactured from high-quality 510L carbon structural steel, specifically for heavy-duty applications, ensuring exceptional vehicle strength and extended service life.
Enhanced Safety & Protection: Features an advanced intake and exhaust system coupled with an automatic protection device, delivering superior flameproof performance and dependable safety measures for underground operations.
