That properly guarantees merchandise assembly accuracy, lowering the failure fee and bettering the stability.

eight.12 automated spraying assembly line, the total equipment undertake impeller blasting to guarantee the cleanliness of steel surface area and eradicate the inner tension producing in welding method, boost the toughness and metal area hardness, improve painting adhesion. Two primer, a paint spraying technological innovation, stunning physical appearance, corrosion resistance has enhanced much more than twice than the lifestyle of common spraying procedure. System, the little vehicle, fence and other little parts undertake hot dip galvanized soon after acid phosphate remedy, rust resistance stronger.


9.Hoisting, derric ept and slewing mechanism, with comprehensive basic safety such as torque, fat restrict. The steel wire rope broken rope unit. Assortment of the auto style towards loss and broken shaft, this kind of as tilting device. The electrical adopts overload protection, the layout of PLC self-prognosis system, it really is hassle-free to routine maintenance.
