It can maintain not rusted for 10 a long time .Swiss screw-thread bolts of preload promote thirty per cent than conventional bolts. Bodyweight limiter uses the rigidity ring framework and solid aluminum shell utilised Hoisting, derric ept limiting stopper to extend support daily life.


seven.Huge constructions as mast area, turn in a position, best package and hoisting jib adopt sophisticated tools as NC device device, drilling machine, milling equipment processing soon after welding. That efficiently assures goods assembly accuracy, reducing the failure fee and improving the security.

8.12 computerized spraying assembly line, the whole equipment undertake impeller blasting to ensure the cleanliness of steel surface area and get rid of the inner stress producing in welding approach, increase the strength and steel floor hardness, improve portray adhesion. Two primer, a paint spraying technology, lovely visual appeal, corrosion resistance has elevated far more than two times than the existence of common spraying approach. System, the little car, fence and other modest pieces undertake very hot dip galvanized right after acid phosphate remedy, rust resistance more robust.


nine.Hoisting, derric ept and slewing system, with total safety this kind of as torque, weight limit. The metal wire rope broken rope system. Variety of the automobile design towards loss and damaged shaft, these kinds of as tilting unit. The electrical adopts overload defense, the design and style of PLC self-analysis technique, it’s handy to servicing.
