The ZDRU-10 trackless passenger truck is a trackless transportation equipment designed and manufactured specifically for underground mines.

The ZDRU-10 Personnel Carrier is powered by a diesel engine, with hydraulic mechanical transmission, four-wheel drive, forward driving, front axle hydraulic steering, large steering angle, flexible turning, and small radius. It is suitable for medium section roadway operations.

     1.Technical Characteristics:

• Power System:The power system adopts Yunnei National III water-cooled low pollution engine;
• Transmission:The power transmission system adopts a power shift gearbox, a fully enclosed wet brake axle, and mining patterned cut resistant inflatable tires;
• Braking System: The driving brake adopts wet multi disc hydraulic brakes; The parking brake adopts a manual directional valve to control the axle spring brake, which is safe and reliable;
• Frame:The frame is an integral structure with reliable performance;
• Adopting a closed cab is safer and more comfortable.
• Adopting a rear orientation for easy entry and exit of personnel, with good safety.

     2.Safety Measures:

• Safety Gear: Operators must wear safety helmets, carry self-rescue devices, and use mining lamps when entering the well.
• Regular Maintenance: Regular inspections and prompt addressing of hidden dangers.
• No Maintenance During Operation: Strictly prohibited to conduct maintenance while the machine is running.
• Safety During Welding/Cutting: Confirm absence of flammable or explosive materials before maintenance.
• Exhaust Pipe Precautions: Avoid physical contact with the hot exhaust pipe.
• Hydraulic System Maintenance: Pressure must be relieved before starting any repairs.
