    Currently, wear-resistant steel under 6 mm is mainly used in lightweight dumper carriage as the thinnest available specification is 2 mm. Its shape and bending property are both in the domestic top level (the only cargo carriage that side wall and bottom plate are made of 3mm wear-resistant steel). The advantage of wear-resistant dump truck compared with traditional one lies in:

    1. light weight and reduced energy consumption, 50% and 33% weight loss compared with grade of 345 MPa and 700MPa respectively;

    2. compared with the original material, it has better wear resistance (3.5 times higher), longer service time and less maintenance;

    3. the anti-smashing performance of carriage is improved under different working conditions.

     

     
    The bottom plate and side wall of U-shaped groove dump truck are made of high quality tempered and wear-resistant steel NM450
