First, more energy saving and environmental protection

1. Adopting new environmentally friendly engine, low speed torque, low fuel consumption, high working efficiency, reliable and durable. The arrangement of the intake line is optimized to reduce the intake resistance, increase the intake air quantity, and improve fuel utilization.

2. It adopts a cross-stage large displacement constant power variable pump with high volumetric efficiency. By properly adjusting the pump power and adopting a new generation of lower pressure main valve, the machine has lower energy consumption, faster response and more precise control.
Second, more reliable and durable

1. Re-optimize the design of the boom and the stick, and further strengthen the key parts. The tooth is mounted by a cross pin, and the new pin fixing method is adopted to effectively prevent the tooth cover from falling off.

2. The tail frame of the rotary platform adopts a box structure to increase the overall rigidity, prevent deformation after long time work, high reliability, and durability.

3. Adopting the new X-frame chassis system, the inside of the lower frame passes through the reinforcing ribs to form a large-section box body with good circumferential force bearing performance, which can apply the stress transmitted on the vehicle more evenly on the track beam, reducing the track. Local stress concentration of the beam.

4. The new type of crawler belt adopting international standards has higher reliability and is equipped with double-row rail clamps to ensure the track is stable and stable under severe working conditions.

Third, more comfortable and safe

1. The cab has a simple, smooth and airy appearance. It is covered with a large area of glass and has a wider field of vision. The driver can clearly grasp the surrounding environment. The cab is equipped with a new silicone oil shock absorber, which greatly reduces the fatigue of the driver's long-term operation and improves work efficiency.

2. Increase the glass sliding window on the right side of the cab and open the left and right sliding windows of the cab to form convection of the wind. At the same time, it is convenient for the driver to communicate with people on both sides of the vehicle.

3. The new seat suspension device and headrest make the driver's work more comfortable, and the walking pedal is improved to make the operation easier and more comfortable.

4. Humanized detail design, all indoor operating elements are scientifically and reasonably arranged according to ergonomics theory, adding humanized configuration such as cup holder, backup power supply, magazine bag, storage box, etc., to maximize the convenience of operation. Sex and comfort.

5. The oil pipe of the arm cylinder is arranged on both sides of the oil cylinder to prevent the oil cylinder steel tube from being damaged due to excessive movement when the boom is lifted under the height-limited working condition.

6. The layout of the three-inch work lights is reasonable, which ensures the safety of the operator's night work.

Fourth, convenient maintenance

1. The glass liquid water bottle is installed on the back side of the cab to facilitate the observation of the glass water level.

2. The slewing motor gear oil filling port is led out to the top of the fuel tank, which is convenient for adding gear oil, reducing maintenance difficulty and greatly reducing maintenance man-hours.

3, open the rear hood, oil filter, diesel filter, air filter at your fingertips, easy maintenance.
