7.Large structures as mast segment, flip able, leading kit and hoisting jib undertake innovative equipment as NC device instrument, drilling device, milling equipment processing right after welding. That efficiently guarantees products assembly accuracy, reducing the failure charge and bettering the protection.


eight.twelve computerized spraying assembly line, the total device adopt impeller blasting to make sure the cleanliness of metal area and eradicate the inside anxiety producing in welding process, increase the power and steel surface hardness, increase portray adhesion. Two primer, a paint spraying technologies, beautiful look, corrosion resistance has increased more than 2 times than the lifestyle of ordinary spraying method. System, the little car, fence and other modest items undertake scorching dip galvanized right after acid phosphate therapy, rust resistance more powerful.


9.Hoisting, derric ept and slewing mechanism, with total security such as torque, bodyweight restrict. The steel wire rope broken rope system. Range of the car style against loss and broken shaft, this kind of as tilting gadget. The electrical adopts overload defense, the style of PLC self-analysis technique, it’s handy to maintenance.



ten.Dahan three creation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to much more than 50 international locations and locations. We have a lot more than one thousand sets right after-revenue services community. We carried out the earliest stagnation stage services method in this tower crane ept that ensure the good quality of service and performance. Otherwise, better to get rid of customer’s worries.
