Product DescriptionProduct DescriptionZDT420 underground mining truck : Trackless transportation equipment.The ZDT420 underground mining truck mainly used in conjunction with scrapersin underground excavation and mining operations. Transporting ores and variousmaterials can greatly improve operational efficiency and is an important equipmentfor achieving trackless mining.1.Technical Characteristies:Power System: Equipped with a Deutz air-cooled engineTransmission: Utilizes a gearbox and torque converterBraking System: Driving Brake: Wet multi-disc spring brake with hydraulicrelease. Parking Brake: Spring brake on the drive axle.Frame: Centrally hinged structure for improved adhesion performance.Steering:Hydraulic power steering with a single steering cylinder.2.Performance Highlights:Diesel Engine: Powered by a reliable diesel engine.Four-Wheel Drive: Ensures traction and maneuverability.Lateral Driving: Allows flexibility in tight spaces.Central Articulated Hydraulic Steering: Large steering angle for precise control.Small Turning Radius: ldeal for medium section tunnel operations.3.Safety Measures:Safety Gear: Operators must wear safety helmets, carry self-rescue0devices, 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.Usage Conditions for the ZDT420 underground mining truck1.Tunnel Specifications: Suitable for tunnels with a cross-sectional size of 4 meters (height) × 4 meters (width) and above. Requires a firm top plate. Minimum turning radius of ≥ 8.5 meters on the outside. Road slope should be ≤ 14°. Adequate ventilation and drainage in the workplace2.Environmental Factors: Ambient temperature within the tunnel: -5°C to 40°C. Maximum relative humidity (at 25°C): Not more than 85%. Altitude of usage location: Not exceeding 1000 meters.In high-altitude areas (above 1000 meters), power reduction is required for operation.3.Fuel Requirements: The sulfur content of the fuel used in this machine must not exceed 0.2%. 4.
