25 Tons Underground Dump Truck (AJK-25)

AJK-25 underground dump truck

AJK-25 underground dump truck is mainly used in underground mine, particularly for transporting the ore to the surface. It can also be used for the construction of railway, highway, water conservancy and other tunnel projects. This machine employs international advanced electronic control engine-- Cummins Eninge: Exhaust can meet the standards of the third stage of off-high way Mechanical Equipment in Europe and U. S. A; Breaking up the restriction of traditional speed limit, the maximum speed can reach as high as 31km/h; Heavy load traction can be achieved on slopes with powerful engine, and its transport efficiency can realize 50 percent improvement higher than traditional truck of 25 tons; The system can response rapidly; Strong braking force; The parameter structural design ensures the strength to the maximum extent, and thus the entire vehicle system configuration and overall technology can be synchronous with the world.
