six. Consideration to detail good quality.  High-strength bolt undertake shipborne scale DACROMET technological innovation. It can hold not rusted for 10 several years .Swiss screw-thread bolts of preload advertise 30 percent than conventional bolts. Fat limiter utilizes the stress ring framework and forged aluminum shell employed Hoisting, derric ept restricting stopper to prolong support life.

7.Big structures as mast section, turn in a position, prime kit and hoisting jib undertake advanced products as NC device instrument, drilling equipment, milling machine processing after welding. That properly assures goods assembly accuracy, lowering the failure rate and improving the security.


8.twelve automatic spraying assembly line, the whole equipment adopt impeller blasting to make certain the cleanliness of metal floor and get rid of the inside tension generating in welding approach, enhance the strength and metal floor hardness, boost portray adhesion. Two primer, a paint spraying technologies, gorgeous appearance, corrosion resistance has enhanced much more than 2 times than the existence of regular spraying process. System, the tiny automobile, fence and other tiny items undertake scorching dip galvanized after acid phosphate therapy, rust resistance much better.


nine.Hoisting, derric ept and slewing system, with full basic safety these kinds of as torque, bodyweight restrict. The metal wire rope broken rope device. Range of the automobile style towards decline and broken shaft, this sort of as tilting gadget. The electrical adopts overload protection, the design and style of PLC self-diagnosis system, it really is convenient to routine maintenance.

10.Dahan three manufacturing bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to more than 50 nations around the world and locations. We have far more than a thousand sets following-sales service network. We carried out the earliest stagnation point provider mode in this tower crane ept that guarantee the top quality of provider and effectiveness. Otherwise, better to get rid of customer’s worries.
