ZDL203N Underground Loader: Enhancing Trackless Mining Efficiency

The ZDL203N underground loader is purpose-built for underground mines, specifically designed to improve operational efficiency in conjunction with mining trucks during excavation and mining operations. Here are its key features:

     1.Technical Characteristics:

• Power System: Equipped with a Deutz air-cooled engine.
• Transmission: Utilizes a gearbox and torque converter.
• Braking System:
  • Driving Brake: Wet multi-disc spring brake with hydraulic release.
  • 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: Ideal for medium section tunnel operations.、

     3.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.

The ZDL203N loader plays a crucial role in achieving efficient and safe trackless mining operations.

Usage Conditions for the ZDL203N Underground Loader

     1.Tunnel Specifications:

• Suitable for tunnels with a cross-sectional size of 5 meters (height) × 2.5 meters (width) and above.
• Requires a firm top plate.
• Minimum turning radius of ≥ 4.3 meterson the outside.
• Road slope should be ≤ 14°.
• Adequate ventilation and drainagein the workplace.

     2.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 reductionis required for operation.

     3.Fuel Requirements:

• The sulfur content of the fuel used in this machine must not exceed 0.2%.

     4.Safety Precautions:

• Strictly prohibitedin places with flammable and explosive gases (such as gas and coal dust).

         Ensure compliance with these conditions for safe and efficient operation of the ZDL203N underground loader.
