The ten rewards of DaHan tower crane 

  1. With 56,000 sets of market place quantity and excellent track record, EPT tower crane ranks the initial location in China tower crane ept in the past many years. EPT often adheres to the benefit that supply the most useful tower crane and provider for the buyer, with the greatest expense performance in the business. 



2. EPT tower crane owns the major technology R&D crew, the item top quality handed numerous experiments with rigorous tests. Normally, EPT has 16 a long time of manufacturing technological innovation and abundant activities in quality management. Till now, above a hundred national technological innovation patents of tower crane have been set into use previously.


three.In buy to promise the trustworthiness of Other torque limiters are not made to operate in steady slip environments, and when the torque limit is approached – for instance in the circumstance of an overload – the output of the driving aspect should be reduced soon after a momentary slip issue – or it should then be decoupled from the driven unit until the overload is corrected. Seek the advice of the manufacturing unit for extra data on your particular software.tower crane top quality and lessen the cost, all raw supplies are right equipped by popular makes like Baosteel and Wisco. Raw supplies for major areas this sort of as common section major limbs, tower caps adopt Q345B metal, as a result the tensile energy enhanced by 30% and the tower crane gets to be a lot more risk-free and reputable. 


4.Dahan tower crane is the organization which to start with started out to use the robot welding lines. At existing, we have a fully automatic robot welding generation line for mast sections fabrication manufactured up by much more than one hundred welding robots. The generation line is composed with automated 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, substantial quality of welding and secure efficiency.


5. All elements and components of EPT tower crane use quality brand names. Electric powered gear with Schneider converter, aviation plug, stainless metal distribution box and a few linkage console has functions of reduced failure rate and simple installation.
Hoisting system is supplied by major company Jiangte Motor or HangZhou Shengjian, all with motor oil, free maintenance, higher trustworthiness and minimal upkeep fee.
Slewing support employs HangZhou Fangyuan model or Rothe Erde manufacturer, two times tempering processing helps make far more efficiently procedure and for a longer time tower crane service daily life.


6. Focus to depth high quality.  High-energy bolt adopt shipborne scale DACROMET engineering. It can hold not rusted for ten several years .Swiss screw-thread bolts of preload market thirty percent than conventional bolts. Weight limiter makes use of the rigidity ring framework and forged aluminum shell employed Hoisting, derric ept limiting stopper to lengthen service life.



seven.Massive structures as mast section, change capable, best kit and hoisting jib undertake innovative gear as NC machine tool, drilling device, milling machine processing soon after welding. That successfully guarantees products assembly precision, minimizing the failure charge and strengthening the stability.


eight.12 automatic spraying assembly line, the complete machine undertake impeller blasting to make certain the cleanliness of steel surface and remove the inside anxiety producing in welding method, increase the power and metal area hardness, improve painting adhesion. Two primer, a paint spraying technology, stunning visual appeal, corrosion resistance has enhanced much more than two times than the existence of ordinary spraying procedure. Platform, the modest automobile, fence and other tiny pieces adopt sizzling dip galvanized right after acid phosphate therapy, rust resistance stronger.


nine.Hoisting, derric ept and slewing system, with complete security this kind of as torque, weight limit. The metal wire rope broken rope device. Selection of the vehicle design and style in opposition to decline and broken shaft, such as tilting system. The electrical adopts overload protection, the style of PLC self-analysis program, it’s handy to upkeep.



ten.Dahan three production bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to a lot more than 50 international locations and areas. We have more than one thousand sets following-revenue services network. We carried out the earliest stagnation point support manner in this tower crane ept that make sure the top quality of support and effectiveness. Otherwise, better to take away customer’s problems.
