The ZDT210 Underground Mining Truck is a trackless transportation equipment designed and manufactured specifically for underground mines. Mainly used in conjunction with scrapers in underground excavation and mining operations. Transporting ores and various materials can greatly improve operational efficiency and is an important equipment for achieving trackless mining. The ZDT210 Underground Mining Truck is powered by a diesel engine, with hydraulic mechanical transmission, four-wheel drive, lateral driving, rear dump truck body, central articulated hydraulic steering, large steering angle, flexible turning, and small radius. It is suitable for medium section tunnel operations and has the following technical characteristics:

● The power system adopts a Deutz water-cooled low pollution engine; ● The power transmission system adopts DANA gear transmission, spring brake hydraulic release drive axle, and mining resistant cutting tires;; ● The driving brake adopts a wet multi disc spring brake hydraulic release brake; MICO filling valve and brake valve; The parking brake adopts a spring brake on the drive axle for braking; ● The frame adopts a central hinged rotary structure to improve the adhesion performance of the entire machine; ● The steering system is a hydraulic power steering system with dual sided steering cylinders; ● Rear dump truck, convenient for dumping ores and materials. Safety warning ● The operator of this machine must wear a safety helmet and carry a self rescue device and a mining lamp with them when entering the well; ● This machine must be regularly maintained and inspected, and any hidden dangers should be promptly addressed; ● It is strictly prohibited to conduct maintenance while the machine is in operation; ● When the machine is undergoing maintenance, the power must be cut off and the words “under maintenance, no starting” must be hung; ● When conducting maintenance under the raised car body, the car body must have firm and reliable support; ● When entering the machine for welding and cutting, safety measures must be taken after confirming that there are no flammable or explosive materials present Only with full measures can operations be carried out;

● When the engine is running and the exhaust pipe has not cooled down after shutdown, it is strictly prohibited to have physical contact with the muffler ● The surface of the exhaust pipe to avoid serious injuries such as burns; ● When repairing the hydraulic system of this machine, the pressure must be completely relieved before starting the operation.
