XCMG official 50 ton hydraulic excavators mining machinery XE500HB for sale

XCMG official 50 ton hydraulic excavators XE500HB.

1.Products with the same tonnage have the highest energy efficiency ratio, the industry\'s first adaptive boom potential energy recovery and undisturbed utilization technology, and fuel consumption is reduced by more than 15% compared with products of the same tonnage;

2.The working device has the highest structural strength. In view of the heavy load conditions of the mine, the key parts adopt large castings and local variable cross-section structures. The bending and torsion resistance of the box section are increased by more than 30%, and the service life of the structural parts is greatly improved;

3.Original dual-system automatic switching technology, using the critical state fuzzy control method to realize the automatic switching between the energy recovery and reuse system and the original working system to ensure the operation requirements under different working conditions;

4.The self-developed energy recovery system components have passed the bench test verification, in which the motor has undergone more than 2 million durability tests, with long service life, reliability and durability;

5.The energy storage system adopts automatic pressure relief function, and the gas circuit adopts a double ball valve cut-off device, which can manually cut off the pressure of the accumulator according to the maintenance requirements, making the maintenance safer.
