LOVOL FR560E2-HD Tunnel Crawler Excavator

● Performance

High-power engine, a new generation of QSM11 engine imported from the United States, with a rated power of 298kW, specially designed to provide strong power for mining operations.

Its unique PT fuel control and injection technology is more precise and more fuel efficient than traditional electronically controlled high-pressure common rail technology.

The upgraded QSM11 engine meets China’s Stage III diesel for non-road mobile machinery, US Tire3 and EU Stage IIIA emission standards.

In the research and development stage of the electronically controlled positive flow control system, Lovol combines the latest technological achievements in related fields in the world and is committed to a unique overall system. The variables of the main pump and the movements of the main valve spool are synchronized, making the electronically controlled positive flow control system more sensitive in operation and achieving the best working experience with fast and smooth movements.

Original energy-saving system. For the first time, an independent cooling circuit system is used to provide stable hydraulic oil for the entire machine, so that the entire hydraulic system can always operate in a stable environment, improving the reliability of the hydraulic circuit system. Variable back pressure technology is also used on the independent cooling circuit, which greatly reduces the return oil pressure loss and reduces the fuel consumption of the entire system by 9% compared with before.

● Reliable

Continuously optimized design, stress testing, welding process and plate research to comprehensively improve the life of key structural parts;

The boom adopts a box-type structure, high-strength steel plate, and cooperates with robot welding technology to more than double the service life under mining conditions.

Complete machine test: CL-6 complete machine test site covers an area of ​​more than 300 acres, including various working conditions of earthwork, stonework, sand and gravel, covering bumpy vibration enhanced test, noise test, operating efficiency, fuel consumption, walking test and climbing In testing and other venues, each new product must undergo more than 2000 hours of intensive combined testing (including excavation, crushing, bumping, climbing and various performance tests).

efficiency

Excellent performance makes loading more efficient. The high-power engine and the high-performance hydraulic system are perfectly matched. Under heavy-load conditions, the main controller will automatically adjust the power and speed according to changes in the load to ensure that under heavy-load conditions. The high output power under working conditions improves the efficiency of the entire machine under heavy load conditions, increasing the loading capacity per unit time by 15%. The rotation torque is increased, making loading and stone sweeping operations more efficient.

Super strong digging force, on the basis of ensuring static digging force, we are committed to the research and development of dynamic digging force. When encountering large resistance during the digging process, the system will automatically detect the pressure and automatically adjust the output pressure to ensure that Powerful mining effects during dynamic mining.

Ultra-low fuel consumption, thanks to the latest technology and hydraulic systems, the proven Cummins 6-cylinder engine performs well both in terms of hourly fuel consumption and fuel efficiency.

● Safe and comfortable

The cab is equipped with high-quality mechanical suspension seats to meet the driver’s comfort needs. The cab that complies with TOPS\FOPS standards makes the operation safer.

The joystick conforms to ergonomic design, with smaller operating force and less fatigue during long-term operation.

A low-noise main pump is used and the whole machine is noise-reduced. The cab is installed on a silicone oil shock absorber, which can significantly reduce the vibration of the cab.
