2. Key Features

2.1 Industry-leading Fuel Efficiency

The intelligent power matching system automatically adjusts engine output and hydraulic flow according to actual load, with an optional ECO mode that reduces fuel consumption by 10-15% compared to same-class competitors without sacrificing working efficiency. The auto idle stop function further cuts unnecessary fuel waste during standby.

2.2 High Durability for Harsh Scenarios

Reinforced high-strength steel boom and arm, with dust-proof sealed pins and self-lubricating bushings to extend service life
Heavy-duty undercarriage with reinforced track links, rollers and idlers, designed for long-term operation in mining and quarry sites
Parallel independent cooling system ensures stable operation even in 45°C high temperature environments
Core components (engine, hydraulic pump, valve) have passed 1 million+ hours of field verification globally

2.3 Operator Comfort

ROPS/FOPS certified fully sealed pressurized cab, internal noise controlled below 70 dB(A)
Fully adjustable air suspension seat, ergonomic control joysticks, and 10-inch full-color intelligent monitor for real-time equipment status display
