The 10 positive aspects of DaHan tower crane 

  1. With 56,000 sets of industry volume and exceptional track record, EPT tower crane ranks the initial place in China tower crane ept in the past decades. EPT often adheres to the benefit that source the most beneficial tower crane and support for the buyer, with the greatest value efficiency in the market. 



2. EPT tower crane owns the major engineering R&D team, the item top quality handed many experiments with rigid testing. Or else, EPT has 16 years of creation technology and rich ordeals in quality administration. Till now, in excess of a hundred national engineering patents of tower crane have been place into use previously.


3.In buy to assure the dependability of tower crane quality and lessen the cost, all uncooked resources are straight equipped by famous makes like Baosteel and Wisco. Uncooked materials for major elements such as normal section principal limbs, tower caps undertake Q345B steel, therefore the tensile strength improved by 30% and the tower crane gets much more risk-free and dependable. 


4.Dahan tower crane is the organization which first of all started out to use the robot welding strains. At present, we have a fully computerized robotic welding generation line for mast sections fabrication made up by more than 100 welding robots. The manufacturing line is composed with automated materials preparing, welding and maching. All major elements of Dahan tower crane use robot welding, with the most ept carbon dioxide blended with argon fuel shielded welding, it has deep depth of fusion, high high quality of welding and secure overall performance.


five. All areas and parts of EPT tower crane use premium makes. Electrical gear with Schneider converter, aviation plug, stainless metal distribution box and a few linkage console has functions of minimal failure price and straightforward set up.
Hoisting mechanism is provided by major maker Jiangte Motor or HangZhou Shengjian, all with engine oil, totally free upkeep, large dependability and minimal servicing rate.

6. Attention to element top quality.  High-power bolt adopt shipborne scale DACROMET technologies. It can preserve not rusted for 10 years .Swiss screw-thread bolts of preload promote 30 % than traditional bolts. Bodyweight limiter utilizes the pressure ring structure and forged aluminum shell employed Hoisting, derric ept limiting stopper to prolong service lifestyle.



seven.Large buildings as mast area, turn in a position, leading kit and hoisting jib adopt innovative equipment as NC equipment resource, drilling equipment, milling machine processing following welding. That effectively ensures merchandise assembly accuracy, reducing the failure charge and enhancing the stability.


8.12 computerized spraying assembly line, the whole equipment adopt impeller blasting to guarantee the cleanliness of metal floor and eliminate the inner stress generating in welding method, improve the toughness and steel surface hardness, enhance portray adhesion. Two primer, a paint spraying technology, lovely visual appeal, corrosion resistance has improved a lot more than twice than the existence of ordinary spraying approach. Platform, the little auto, fence and other little pieces undertake sizzling dip galvanized soon after acid phosphate therapy, rust resistance stronger.


nine.Hoisting, derric ept and slewing system, with total basic safety this kind of as torque, fat limit. The metal wire rope damaged rope system. Variety of the vehicle style towards loss and damaged shaft, these kinds of as tilting system. The electrical adopts overload defense, the layout of PLC self-prognosis system, it is practical to routine maintenance.



10.Dahan three creation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to much more than fifty nations and regions. We have a lot more than one thousand sets soon after-sales service community. We carried out the earliest stagnation level services method in this tower crane ept that make certain the top quality of support and effectiveness. Otherwise, better to get rid of customer’s anxieties.
