Audited Supplier More environmentally friendly, more dynamic, faster, lower fuel consumption
- new Tier3 engine with advanced diesel high pressure common rail electronic control injection technology
- fully and thoroughly combustion of diesel fuel, greatly improving performance
- multi-fuel filtering system ensures long service life of the engine while reducing harmful gas emissions and being more
environmentally friendly
- optimize the oil circuit design of the main control valve, and improve the operating speed and compound operating capacity
- the loading operation is more efficient and the amount of work per hour is larger
- lower operating costs and higher returns
IPC main pump intelligent control system
VPC variable power control system
- IPC system reduces fuel consumption by intelligently controlling the main pump flow through the operating handle
- VPC system can realize variable control of pilot pressure to ensure operating speed in all working modes
Coordinate with fuel performance to ensure high efficiency and low consumption
Structural parts last longer
- install heavy duty large and small arms with better durability, use cast steel products to improve strength and increase
durability by 1.5 times
- the walking and rotating motors are designed by heavy industries to enhance their durability
- the thickness of the lower support ring increased, and the welding strength of the lower frame increased by 20%
Higher cooling performance
- adopt high capacity and high efficiency direct cooling fan
- cooling module sealing sponge is oil resistant,
Polyurethane sponge with higher heat resistance
Durability shaft, sleeve and resin gasket
- increase the lubricity of shaft and sleeve, improve the abrasion resistance and prolong the butter injection period
- suitable for resin core, increase side lubrication, prevent wear and abnormal noise
- operation device is loose to minimize
Electrical system performance is enhanced
- MCU is sealed with silica gel to prevent water injection and vibration resistance
- strengthen anti-corrosion treatment while increasing the capacity of the generator
- enhanced durability and reliability of pressure sensors
Durability tank
- adopt the board + support style, the fatigue life of the welding part increases 3.6 times (35% reduction in relative stress)
- increase the size of the fuel injection port (prote83 to prote104) to improve the convenience and prevent overflow during injection
