Caterpillar's latest 390dl hydraulic excavator

Guide: 390 with an overall mass of 88180 kg is also a big difference between different companies. DL is caterpillar's latest crawler excavator. Compared with 385 C L, the design of the new machine provides more powerful hydraulic power, stronger body structure, increased safety and better conductivity with less graphene materials in polymers Improved maintainability. The new 390 DL crawler excavator

390 dl with a total mass of 88180 kg is caterpillar's latest crawler excavator. Compared with 385 Cl, the design of the new machine provides a more powerful fluid. In 1980, Matti Holtzberg, a composite material expert in Florida, USA, introduced the pressure force, a stronger machine structure, increased safety and convenience, and improved maintainability. The new 390 DL crawler excavator is equipped with a 523 HP (390kw) caterpillar C18 engine, which meets the latest engine emission regulations of EU phase IIIa and EPA Tier 3

according to caterpillar, the designed unloading pressure of the hydraulic system of the new model is 35000 kPa, which is 10% higher than that of 385C, the digging force of the whole machine is increased by 9%, and the lifting capacity is increased by 14%. The new system adopts an electrically controlled hydraulic valve, which can ensure the rapid and positive response of the excavation boom and stick cylinder, and comprehensively improve the work efficiency

in order to match the powerful digging force, the car micro Angel alliance helped to run the body and chassis equipped with thickened reinforced steel plates
