Raw materials for primary parts this kind of as regular segment primary limbs, tower caps adopt Q345B steel, hence the tensile energy increased by thirty% and the tower crane gets to be more safe and dependable. 

4.Dahan tower crane is the enterprise which to start with commenced to use the robot welding traces. At current, we have a fully automated robot welding generation line for mast sections fabrication created up by far more than 100 welding robots. The creation line is composed with computerized content planning, welding and maching. All major areas of Dahan tower crane use robotic welding, with the most ept carbon dioxide blended with argon fuel shielded welding, it has deep depth of fusion, higher quality of welding and secure functionality.

6. Attention to element quality.  High-strength bolt undertake shipborne scale DACROMET engineering. It can preserve not rusted for ten a long time .Swiss screw-thread bolts of preload encourage thirty % than standard bolts. Fat limiter uses the rigidity ring construction and cast aluminum shell utilized Hoisting, derric ept restricting stopper to prolong service lifestyle.

seven.Massive structures as mast area, switch able, top kit and hoisting jib adopt innovative equipment as NC equipment device, drilling device, milling equipment processing following welding. That properly guarantees items assembly precision, lowering the failure fee and enhancing the security.


eight.12 computerized spraying assembly line, the whole machine undertake impeller blasting to ensure the cleanliness of metal surface area and get rid of the interior tension making in welding procedure, improve the strength and steel surface area hardness, improve portray adhesion. Two primer, a paint spraying technologies, lovely look, corrosion resistance has elevated more than twice than the lifestyle of ordinary spraying method. Platform, the small automobile, fence and other tiny items adopt hot dip galvanized soon after acid phosphate therapy, rust resistance more robust.


9.Hoisting, derric ept and slewing mechanism, with comprehensive protection such as torque, fat restrict. The steel wire rope damaged rope gadget. Assortment of the car design and style against loss and broken shaft, this sort of as tilting gadget. The electrical adopts overload safety, the layout of PLC self-prognosis system, it really is practical to maintenance.
