Features

• It is equipped with a Cummins high-power engine, which meets the national three emission standards and has strong power.
• The new cooling technology driven by hydraulic pump can effectively improve the efficiency of fan utilization, save energy and fuel, and create higher benefits for customers.
• Kawasaki’s main pump and main valve are used, which are reliable and durable.
• Equipped with Kawasaki positive flow electronic control system, which has faster response speed, better control performance, energy saving and high efficiency.
• The rotary motor adopts the core components imported from Japan, which is more reliable and accurate.
• Fully optimize the process of structural parts, and use high-performance welding robots for automatic welding. The boom and stick cylinders use a new type of bushing with high surface hardness, oil storage holes and double-layer wear-reducing materials.
• The chassis is widened to make the vehicle more stable.
• Equipped with a rear panoramic camera as standard, it can effectively reduce the blind spot of the driver’s operation and make the driving of the whole machine safer.
• The display can realize man-machine communication, and can monitor engine speed, coolant temperature, oil pressure, fuel level, etc., to achieve precise intelligent control and monitoring of equipment performance.
