Suspension system of engineering vehicle is a vibration damping device for vehicles, which is suitable for different road conditions. One way variable damping technology and matching technology of oil and gas parameters are adopted to achieve excellent damping performance. The product is applied to all series of mining dump trucks and all-series of all-terrain truck cranes.
1.Adopt high strength alloy steel casting and forging integrated molding technology to ensure the safety of heavy haul and high frequency products.
2. Adopt high frequency and high speed sealing match, oil and gas hybrid seal technology, the life can reach 20000h.
3.Special treatment technology forms compact hardened layer on the surface of piston rod with wear resistance being improved more than 2 times by comparing with electroplating and corrosion resistance reaching CASS 480h 9.8 grade.
4. Multilayer sliding-column technology achieves inclined load proof capability leading the industry, making back&forth and rotational compound movement possible.
