six. Consideration to detail high quality.  High-energy bolt adopt shipborne scale DACROMET engineering. It can hold not rusted for 10 a long time .Swiss screw-thread bolts of preload market thirty % than classic bolts. Excess weight limiter makes use of the pressure ring structure and forged aluminum shell utilised Hoisting, derric ept restricting stopper to extend service daily life.

seven.Big constructions as mast segment, change in a position, leading package and hoisting jib undertake sophisticated products as NC machine device, drilling device, milling machine processing after welding. That effectively assures merchandise assembly accuracy, reducing the failure charge and bettering the stability.


8.twelve automated spraying assembly line, the whole equipment undertake impeller blasting to make certain the cleanliness of metal surface and get rid of the interior pressure generating in welding process, boost the power and steel floor hardness, boost painting adhesion. Two primer, a paint spraying technological innovation, gorgeous visual appeal, corrosion resistance has elevated far more than twice than the existence of regular spraying procedure. Platform, the tiny automobile, fence and other tiny parts undertake very hot dip galvanized following acid phosphate remedy, rust resistance much better.


nine.Hoisting, derric ept and slewing mechanism, with complete protection these kinds of as torque, fat limit. The metal wire rope broken rope unit. Assortment of the vehicle design against loss and broken shaft, this sort of as tilting system. The electrical adopts overload safety, the style of PLC self-analysis method, it really is convenient to upkeep.

ten.Dahan three production bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to more than fifty countries and locations. We have a lot more than a thousand sets right after-sales provider network. We carried out the earliest stagnation point services manner in this tower crane ept that make certain the good quality of support and performance. Otherwise, better to get rid of customer’s worries.
