Adopt new environmentally friendly engine, high torque at low speed, low fuel consumption, high operating efficiency, reliable and durable. The layout of the intake line is optimized to reduce the intake resistance, increase the intake volume, and improve fuel efficiency.
By adjusting pump power and adopting a new generation of low-pressure main valve, the overall optimization of the hydraulic piping system reduces the energy consumption of the whole machine, the response speed is faster, and the control is more accurate. Industry-leading flow channel design, the work union cancels the traditional bridge design, and the pressure loss is reduced by more than 30%.
The newly upgraded flow priority distribution method makes the combined action of walking + working devices and climbing + working devices far superior to traditional load-sensitive systems. The adaptability to the working conditions of the loaded walking operation is greatly improved.
By increasing the key size of the rotary reducer, the reducer achieves a torque increase of 15%, making the slope operation easier.
The boom, stick, bulldozer structure, and tailstock of the rotary platform were re-optimized, and key parts were further strengthened. Bucket teeth improve abrasion resistance and bucket tooth working durability is increased by 40%, which greatly reduces user operating costs.
The large space cab is spacious and comfortable, and the field of vision is more open. The cab surround sunshade is added; the three-level vibration reduction system is optimized to further improve the seat comfort. Push-pull glass windows on both sides of the cab greatly enhance working comfort.
Added a built-in toolbox for the rotary platform, which makes daily access and storage of tools extremely convenient.
After opening the rear hood, the oil filter, diesel filter, and air filter are within easy reach, and maintenance is convenient.
Widely used in small earth and stone works, municipal construction, road repair, concrete crushing, buried cables, farmland water conservancy construction, garden cultivation and river trench dredging.
