seven.Large structures as mast segment, change in a position, best package and hoisting jib undertake advanced products as NC machine tool, drilling machine, milling equipment processing following welding. That efficiently guarantees products assembly accuracy, minimizing the failure fee and enhancing the stability.


8.12 automated spraying assembly line, the total equipment undertake impeller blasting to guarantee the cleanliness of steel floor and get rid of the inside anxiety generating in welding process, enhance the strength and metal area hardness, enhance portray adhesion. Two primer, a paint spraying technologies, lovely visual appeal, corrosion resistance has elevated more than 2 times than the life of regular spraying process. System, the small auto, fence and other little parts adopt scorching dip galvanized following acid phosphate treatment method, rust resistance more powerful.


nine.Hoisting, derric ept and slewing mechanism, with total security this sort of as torque, weight restrict. The steel wire rope damaged rope system. Range of the vehicle layout in opposition to loss and damaged shaft, this kind of as tilting unit. The electrical adopts overload defense, the style of PLC self-prognosis system, it truly is hassle-free to servicing.



ten.Dahan three generation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to much more than fifty nations and locations. We have a lot more than a thousand sets following-sales service network. We carried out the earliest stagnation position support method in this tower crane ept that ensure the top quality of services and performance. Otherwise, better to remove customer’s anxieties.
