Uncooked resources for major areas such as standard segment primary limbs, tower caps adopt Q345B metal, therefore the tensile power enhanced by 30% and the tower crane turns into a lot more protected and reliable. 


four.Dahan tower crane is the enterprise which first of all began to use the robotic welding lines. At existing, we have a fully automatic robotic welding manufacturing line for mast sections fabrication produced up by much more than a hundred welding robots. The manufacturing line is composed with automatic materials planning, welding and maching. All principal elements of Dahan tower crane use robotic welding, with the most ept carbon dioxide mixed with argon fuel shielded welding, it has deep depth of fusion, substantial top quality of welding and steady overall performance.


five. All components and components of EPT tower crane use premium brand names. Electric powered gear with Schneider converter, aviation plug, stainless steel distribution box and 3 linkage console has attributes of low failure rate and easy installation.

six. Focus to detail quality.  High-toughness bolt undertake shipborne scale DACROMET technological innovation. It can preserve not rusted for 10 several years .Swiss screw-thread bolts of preload promote thirty percent than conventional bolts. Excess weight limiter uses the pressure ring construction and forged aluminum shell utilized Hoisting, derric ept limiting stopper to lengthen support existence.



7.Huge buildings as mast section, turn able, leading package and hoisting jib adopt superior tools as NC device device, drilling equipment, milling device processing after welding. That effectively guarantees items assembly accuracy, reducing the failure fee and enhancing the safety.


8.twelve automated spraying assembly line, the entire machine adopt impeller blasting to guarantee the cleanliness of metal area and eliminate the internal stress producing in welding method, increase the energy and metal surface hardness, improve portray adhesion. Two primer, a paint spraying technologies, beautiful visual appeal, corrosion resistance has elevated more than 2 times than the existence of common spraying process. System, the little vehicle, fence and other modest pieces adopt hot dip galvanized right after acid phosphate treatment method, rust resistance stronger.


9.Hoisting, derric ept and slewing mechanism, with full protection this sort of as torque, fat limit. The metal wire rope broken rope unit. Variety of the auto style against decline and damaged shaft, this kind of as tilting system. The electrical adopts overload safety, the layout of PLC self-analysis system, it’s convenient to maintenance.



ten.Dahan three manufacturing bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to far more than 50 nations and regions. We have a lot more than 1000 sets soon after-revenue provider network. We carried out the earliest stagnation stage services mode in this tower crane ept that make certain the quality of service and efficiency. Otherwise, better to take away customer’s anxieties.
