High power

Strong power and low fuel consumption for higher returns for users

Adopting the original imported engine for high adaptability of environment.

The power system is equipped with the imported Isuzu 6WG1X engine with a rated power of 300kW, which features sufficient torque reserve and smooth output in the effective working range, helping customers to solve the problems under heavy-duty working conditions.

Innovative Technology

Independent Cooling System

1. With completely independent dual cooling system, water radiator and oil radiator are independently controlled without interference; the oil radiator has a one-touch reverse function, with the fan speed automatically adjusted according to the temperature, making radiator maintenance convenient and quick. All these make the radiator convenient and easy to maintain.

2. Hydraulic system
Equipped with internationally branded pump and valve motors, it adopts 36 large-diameter main spool valves, which reduces system pressure loss, improves efficiency, lowers fuel consumption and improves control.

High-strength components

High reliability and long life span

The structural parts of the boom and arm adopt enlarged and widened box structure and built-in multi-channel internal stiffened plate, which is reinforced by the application of high-strength materials.

Four wheels and one belt

sturdy and wear-resistant, stable and reliable.

It is designed with mine-specific heavy-duty four wheels and one belt, with the main frame cross-section heightened and the track guard strengthened, which is sturdy and wear-resistant, stable and reliable.

Convenient maintenance

The oil and diesel are designed to be centralized in the pump compartment for convenient maintenance. Its standard filter element alarm allows real-time monitoring and control of the health status of the oil return system, which is more intelligent and safer.
