ZDL307 DIESEL UNDERGROUND LOADER

ZDL307 Diesel Underground Loader :Trackless loading and short distance transportation equipment

The ZDL307 Diesel Underground Loader mainly used in conjunction with mining trucks in underground excavation and mining operations. Shovel loading of ore and various materials can greatly improve operational efficiency and is an important equipment for achieving trackless mining.

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.
