six. Focus to element high quality.  High-power bolt undertake shipborne scale DACROMET engineering. It can preserve not rusted for ten many years .Swiss screw-thread bolts of preload advertise 30 percent than conventional bolts. Weight limiter utilizes the pressure ring structure and cast aluminum shell utilized Hoisting, derric ept restricting stopper to increase services lifestyle.


seven.Large constructions as mast area, switch in a position, top kit and hoisting jib adopt superior equipment as NC equipment tool, drilling device, milling device processing after welding. That efficiently guarantees goods assembly precision, minimizing the failure rate and strengthening the stability.

eight.twelve automated spraying assembly line, the whole machine undertake impeller blasting to make certain the cleanliness of steel surface and eradicate the inner stress creating in welding approach, boost the power and metal floor hardness, boost portray adhesion. Two primer, a paint spraying technologies, lovely look, corrosion resistance has improved much more than two times than the life of common spraying method. Platform, the tiny automobile, fence and other small items undertake scorching dip galvanized after acid phosphate therapy, rust resistance stronger.


9.Hoisting, derric ept and slewing system, with full basic safety this kind of as torque, fat limit. The steel wire rope damaged rope device. Variety of the auto design against decline and broken shaft, such as tilting system.
