Wheel loaders are mainly used for shovel loading of soil, sand, lime, coal bulk material such as charcoal, can also be used as a light shovel for ore, hard soil, etc.Digging work, so the fatigue strength of the piston rod and the adhesion of the coating the key to hydraulic cylinder design, HOLAM integral forging piston the rod can greatly improve the fatigue strength of the piston rod, nickel chrome plating better impact resistance and corrosion resistance than hard chrome plating It can withstand vibration shocks and harsh working conditions.
