System, the tiny vehicle, fence and other modest parts undertake sizzling dip galvanized following acid phosphate treatment, rust resistance more robust.


9.Hoisting, derric ept and slewing system, with comprehensive security such as torque, weight restrict. The steel wire rope damaged rope system. Assortment of the automobile layout from decline and broken shaft, such as tilting gadget.
