Analysis of performance characteristics

Agile ability to compound work

1. Improve some parameters and performance of the main control valve, improve the speed during compound operation, increase the control of the fine adjustment of the joystick, and automatically adjust the engine speed according to the displacement of the walking joystick.

2. Superior comprehensive rotation performance is more suitable for a variety of compound working conditions, outstanding handling and soft line, easy to operate the driver comfortable, anti-fatigue.

3. Based on strong durability, Doosan rotary motor and reducer are equipped with one type of device, which makes Doosan's excellent ability fully displayed on the slope.

Reliability and durability

1. The optimized design of the enhanced front working device, reasonable layout and structure to strengthen the design of the upper body, strengthen the lower body of the structure, to ensure the reliability and durability of the equipment, can be more in-depth, more close to meet the diversified operation needs of China.

2. Enhanced front working device: large arm reinforcement; The hydraulic cylinder is made of heat-resistant material, which effectively improves the oil leakage inside the hydraulic cylinder and greatly improves its overall strength and life. The newly designed bucket shape increases the digging force and improves the durability.

3. The protection structure of the movable motor cover plate fixed bolt is designed, which can effectively avoid the collision of the bolt in harsh working conditions.

4. The track pin adopts interference fit design, which strengthens the connection strength between the track pin and the pin hole, and greatly improves the durability compared with the gap fit
