The ten positive aspects of DaHan tower crane 

  1. With 56,000 sets of marketplace volume and outstanding popularity, EPT tower crane ranks the very first spot in China tower crane ept in the previous a long time. EPT usually adheres to the value that supply the most worthwhile tower crane and support for the buyer, with the greatest price efficiency in the industry. 



two. EPT tower crane owns the leading technologies R&D staff, the solution good quality passed many experiments with stringent screening. In any other case, EPT has sixteen many years of production engineering and prosperous activities in good quality management. Till now, more than 100 nationwide engineering patents of tower crane have been set into use previously.


3.In purchase to guarantee the reliability of tower crane good quality and decrease the cost, all uncooked supplies are immediately equipped by famous manufacturers like Baosteel and Wisco. Raw materials for principal areas this kind of as normal part primary limbs, tower caps undertake Q345B steel, thus the tensile power improved by 30% and the tower crane turns into a lot more protected and reliable. 


four.Dahan tower crane is the enterprise which to begin with started to use the robot welding strains. At current, we have a fully automated robotic welding manufacturing line for mast sections fabrication produced up by a lot more than one hundred welding robots. The production line is composed with computerized content preparation, welding and maching. All main areas of Dahan tower crane use robot welding, with the most ept carbon dioxide combined with argon gas shielded welding, it has deep depth of fusion, substantial top quality of welding and steady overall performance.


five. All areas and components of EPT tower crane use high quality brand names. Electrical gear with Schneider converter, aviation plug, stainless metal distribution box and a few linkage console has characteristics of lower failure price and easy set up.
Hoisting mechanism is provided by major company Jiangte Motor or HangZhou Shengjian, all with engine oil, cost-free routine maintenance, large reliability and minimal maintenance price.
Slewing help makes use of HangZhou Fangyuan model or Rothe Erde brand, two times tempering processing can make a lot more smoothly procedure and for a longer time tower crane service daily life.


6. Attention to element top quality.  High-power bolt adopt shipborne scale DACROMET technologies. It can preserve not rusted for 10 a long time .Swiss screw-thread bolts of preload market 30 % than classic bolts. Excess weight limiter makes use of the stress ring framework and cast aluminum shell used Hoisting, derric ept restricting stopper to lengthen services existence.



seven.Large constructions as mast segment, switch ready, top package and hoisting jib undertake innovative equipment as NC machine tool, drilling equipment, milling equipment processing soon after welding. That successfully ensures items assembly precision, decreasing the failure rate and bettering the protection.


8.12 automatic spraying assembly line, the entire equipment undertake impeller blasting to guarantee the cleanliness of steel surface area and remove the internal pressure generating in welding process, improve the toughness and metal surface hardness, boost portray adhesion. Two primer, a paint spraying technological innovation, gorgeous appearance, corrosion resistance has enhanced a lot more than two times than the life of regular spraying procedure. System, the tiny automobile, fence and other little pieces adopt very hot dip galvanized after acid phosphate treatment method, rust resistance more robust.


nine.Hoisting, derric ept and slewing mechanism, with full safety these kinds of as torque, fat limit. The metal wire rope damaged rope device. Range of the vehicle design towards reduction and damaged shaft, this sort of as tilting device. The electrical adopts overload safety, the style of PLC self-prognosis method, it truly is hassle-free to maintenance.



ten.Dahan three creation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to far more than 50 international locations and areas. We have more than one thousand sets after-revenue provider network. We carried out the earliest stagnation position provider method in this tower crane ept that guarantee the top quality of service and performance. Otherwise, better to get rid of customer’s problems.
