Uncooked resources for major areas these kinds of as standard segment main limbs, tower caps undertake Q345B steel, thus the tensile strength improved by thirty% and the tower crane turns into much more risk-free and dependable. 


four.Dahan tower crane is the enterprise which to begin with began to use the robotic welding traces. At existing, we have a fully automated robotic welding production line for mast sections fabrication produced up by much more than one hundred welding robots. The creation line is composed with automatic substance planning, welding and maching. All primary parts of Dahan tower crane use robot welding, with the most ept carbon dioxide blended with argon gasoline shielded welding, it has deep depth of fusion, higher quality of welding and stable performance.


five. All areas and factors of EPT tower crane use high quality brands. Electric powered gear with Schneider converter, aviation plug, stainless metal distribution box and 3 linkage console has attributes of low failure rate and straightforward installation.

six. Focus to detail good quality.  High-power bolt adopt shipborne scale DACROMET technological innovation. It can keep not rusted for 10 a long time .Swiss screw-thread bolts of preload promote thirty p.c than conventional bolts. Weight limiter makes use of the tension ring composition and cast aluminum shell employed Hoisting, derric ept restricting stopper to increase services daily life.



seven.Large constructions as mast area, flip able, top kit and hoisting jib undertake superior products as NC device tool, drilling equipment, milling device processing right after welding. That properly assures products assembly accuracy, reducing the failure charge and strengthening the protection.


8.twelve automatic spraying assembly line, the complete equipment adopt impeller blasting to ensure the cleanliness of metal surface and get rid of the inside stress generating in welding method, enhance the strength and metal floor hardness, increase painting adhesion. Two primer, a paint spraying technology, lovely appearance, corrosion resistance has elevated far more than two times than the life of normal spraying method. System, the small automobile, fence and other little items undertake very hot dip galvanized after acid phosphate treatment method, rust resistance much better.


9.Hoisting, derric ept and slewing system, with total basic safety this sort of as torque, excess weight restrict. The metal wire rope broken rope system. Assortment of the automobile style against reduction and broken shaft, this kind of as tilting system. The electrical adopts overload pEvery Zero-Max torque limiter is manufactured from sturdy heat dealt with steel for a extended operational life.rotection, the layout of PLC self-diagnosis program, it is handy to servicing.



10.Dahan three manufacturing bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to far more than 50 international locations and locations. We have much more than one thousand sets after-revenue support network. We carried out the earliest stagnation level provider mode in this tower crane ept that make certain the high quality of support and efficiency. Otherwise, better to take away customer’s worries.
