Raw components for principal elements these kinds of as common area principal limbs, tower caps adopt Q345B metal, as a result the tensile toughness elevated by thirty% and the tower crane turns into much more protected and reliable. 


4.Dahan tower crane is the organization which firstly started to use the robot welding lines. At current, we have a fully computerized robot welding manufacturing line for mast sections fabrication manufactured up by a lot more than a hundred welding robots. The creation line is composed with computerized content preparing, welding and maching. All major areas of Dahan tower crane use robotic welding, with the most ept carbon dioxide combined with argon gas shielded welding, it has deep depth of fusion, large high quality of welding and stable efficiency.


five. All components and parts of EPT tower crane use high quality brands. Electric powered tools with Schneider converter, aviation plug, stainless steel distribution box and 3 linkage console has attributes of minimal failure rate and simple installation.
Hoisting system is presented by foremost company Jiangte Motor or HangZhou Shengjian, all with engine oil, free upkeep, higher trustworthiness and minimal maintenance charge.
Slewing support uses HangZhou Fangyuan brand name or Rothe Erde model, twice tempering processing tends to make far more easily operation and lengthier tower crane service lifestyle.


6. Interest to detail good quality.  High-energy bolt adopt shipborne scale DACROMET technological innovation. It can keep not rusted for ten many years .Swiss screw-thread bolts of preload encourage thirty per cent than standard bolts. Bodyweight limiter uses the tension ring construction and forged aluminum shell utilized Hoisting, derric ept limiting stopper to increase provider lifestyle.



7.Big buildings as mast segment, change in a position, prime package and hoisting jib undertake sophisticated tools as NC equipment instrument, drilling device, milling machine processing following welding. That successfully assures items assembly accuracy, decreasing the failure price and enhancing the protection.

System, the tiny car, fence and other small pieces undertake scorching dip galvanized after acid phosphate remedy, rust resistance much better.


9.Hoisting, derric ept and slewing system, with total security these kinds of as torque, weight limit. The steel wire rope damaged rope gadget. Variety of the vehicle design against reduction and damaged shaft, this sort of as tilting system.
