Product Overview

The TJ-4 Diesel Underground Shovel Loader is a heavy-duty, high-performance loading machine specifically engineered for underground mining, tunneling, and construction operations. Designed to operate in confined and demanding underground environments, this loader combines robust diesel power with a compact footprint, ensuring maximum productivity and maneuverability in narrow tunnels and low-ceiling spaces. Its reinforced structure and advanced hydraulic system guarantee reliable performance in the most challenging conditions.

Technical Features

• Engine Power: Equipped with a fuel-efficient, low-emission diesel engine (typically 45-60 kW) that meets international emission standards, providing ample torque for heavy loading tasks.
• Bucket Capacity: Standard bucket volume of 0.4-0.6 cubic meters, designed for optimal material handling of ore, rock, and debris.
• Operating Weight: Approximately 4,000-5,000 kg, offering excellent stability and traction on uneven underground surfaces.
• Hydraulic System: High-pressure, load-sensing hydraulic system with pilot controls for smooth, precise bucket and boom operations.
• Dumping Clearance: 1,800-2,200 mm dumping height for efficient loading into trucks or conveyors.
• Turning Radius: Compact design with a tight turning radius (less than 4,000 mm) for exceptional maneuverability in narrow drifts.
• Undercarriage: Heavy-duty axles and tires (or optional track system) with reinforced frames to withstand abrasive underground environments.
• Safety Features: Includes ROPS/FOPS certified cabin, emergency stop systems, fire suppression interface, and LED lighting for enhanced visibility.

Application Scenarios

• Underground metal and non-metal mines (gold, copper, iron, limestone, etc.)
• Hydropower tunnel construction and civil tunneling projects
• Subway and railway tunnel excavation
• Underground storage cavern and civil defense projects
• Mucking and material handling in narrow, low-headroom underground spaces

Key Advantages

• Superior Maneuverability: Compact dimensions and articulated steering enable operation in spaces as narrow as 2.5 meters wide.
• High Productivity: Fast cycle times with powerful breakout force (≥45 kN) and quick bucket action for continuous loading.
• Durability: Reinforced bucket, heavy-duty boom arms, and sealed components extend service life in abrasive and dusty conditions.
• Low Operating Costs: Fuel-efficient engine and easy-access maintenance points reduce downtime and total ownership costs.
• Operator Comfort: Ergonomic cabin with vibration isolation, adjustable seat, and intuitive controls for reduced fatigue during long shifts.
• Versatility: Optional attachments (e.g., quick coupler, rock breaker, side-tipping bucket) expand its functionality for diverse tasks.
• Environmental Compliance: Low exhaust emissions and optional exhaust purifier systems meet strict underground air quality regulations.
