The WC19RJ(A) is a 19 ton large-capacity hauler designed for bulk material transport in major underground mining operations. This massive flameproof vehicle features a 62kW ZL4105DZLDFB diesel engine delivering exceptional power for hauling full loads up steep underground ramps. The triple independent wet brake systems—service, emergency, and parking—provide ultimate safety redundancy with automatic engagement upon pressure loss. The riveted 510L high-strength steel frame with cast steel mounts ensures lifelong structural integrity even under the most demanding continuous operation. For large mines requiring maximum productivity per trip, the WC19RJ(A) delivers unparalleled hauling capacity.
Triple Independent Braking: Features three separate wet brake systems (service, emergency, parking) for ultimate safety. All systems are fail-safe, engaging automatically upon pressure loss.
Exceptional Frame Durability: The riveted chassis uses high-strength 510L steel with cast steel mounts, designed for a fatigue-free service life.
Proven Quality: Key components sourced from reputable domestic suppliers ensure reliability and easy maintenance.
