7.Large structures as mast area, change ready, prime kit and hoisting jib adopt superior gear as NC equipment device, drilling device, milling machine processing following welding. That successfully guarantees items assembly accuracy, decreasing the failure fee and strengthening the security.


eight.12 automatic spraying assembly line, the complete machine undertake impeller blasting to guarantee the cleanliness of steel area and eliminate the interior pressure making in welding process, enhance the energy and metal area hardness, enhance painting adhesion. Two primer, a paint spraying technologies, lovely physical appearance, corrosion resistance has enhanced a lot more than 2 times than the life of common spraying approach. System, the tiny car, fence and other tiny items undertake scorching dip galvanized after acid phosphate remedy, rust resistance much better.


nine.Hoisting, derric ept and slewing mechanism, with complete safety these kinds of as torque, fat limit. The steel wire rope broken rope system. Range of the car style in opposition to decline and damaged shaft, this kind of as tilting system.
