XUL621 underground diesel LHD has a bucket capacity of 8m³ and a rated load of 21t, and meets the requirements of mine safety certification. It is suitable for loading, hauling and dumping of materials in mine tunnels and other large tunnels in non-explosive environments, and can meet the loading requirements of mining trucks within 65t during underground mining.
• This machine can adapt to humid and dusty environments of 6m×6m tunnels in underground mines. It is highly intelligent, safe, reliable and stable during operation, which can greatly improve the productivity and profitability of underground mines.
• Low Pollution & Environmental Protection: Effectively reduces exhaust pollution in underground mine working faces and tunnels.
• High Reliability: Imported engine together with DANA gearbox & torque converter, and Kessler drive axles ensure a low failure rate. The working device is made of high-strength plates, featuring a high safety factor and a longer service life.
• Personnel Safety: The cab complies with FOPS/ROPS certification and is equipped with three emergency exits to enhance personnel safety.
• Energy-efficient: It adopts a load feedback variable hydraulic system, providing pressure and flow as needed, which is more efficient and reduces fuel consumption at the same time.
• Convenient Operation: The travel control and working device control are integrated on two electric control joysticks to quickly achieve various actions.
• Driving Comfort: The cab is fixed by multi-directional shock absorbers and equipped with an air suspension seat, providing a better driving experience。
