The ten advantages of DaHan tower crane 

  1. With fifty six,000 sets of market quantity and excellent status, EPT tower crane ranks the very first area in China tower crane ept in the previous decades. EPT constantly adheres to the worth that provide the most valuable tower crane and service for the buyer, with the highest cost efficiency in the industry. 



2. EPT tower crane owns the leading technology R&D crew, the item high quality handed numerous experiments with stringent tests. Normally, EPT has sixteen several years of manufacturing technological innovation and prosperous activities in good quality management. Till now, in excess of a hundred nationwide technology patents of tower crane have been put into use currently.


3.In order to assure the dependability of tower crane top quality and reduce the cost, all uncooked supplies are directly supplied by renowned manufacturers like Baosteel and Wisco. Raw supplies for principal components this kind of as normal section primary limbs, tower caps undertake Q345B steel, therefore the tensile energy enhanced by thirty% and the tower crane becomes much more protected and reputable. 


4.Dahan tower crane is the enterprise which firstly started out to use the robotic welding strains. At existing, we have a fully automatic robotic welding creation line for mast sections fabrication produced up by far more than one hundred welding robots. The creation line is composed with automated material preparing, welding and maching. All major areas of Dahan tower crane use robot welding, with the most ept carbon dioxide mixed with argon fuel shielded welding, it has deep depth of fusion, higher high quality of welding and secure performance.


5. All areas and elements of EPT tower crane use quality brand names. Electric powered products with Schneider converter, aviation plug, stainless metal distribution box and three linkage console has features of lower failure charge and straightforward set up.
Hoisting system is supplied by top company Jiangte Motor or HangZhou Shengjian, all with engine oil, free of charge routine maintenance, high reliability and lower routine maintenance rate.
Slewing assist utilizes HangZhou Fangyuan manufacturer or Rothe Erde model, 2 times tempering processing can make far more easily procedure and more time tower crane support daily life.


six. Attention to element good quality.  High-energy bolt adopt shipborne scale DACROMET technologies. It can hold not rusted for ten years .Swiss screw-thread bolts of preload encourage 30 percent than conventional bolts. Weight limiter makes use of the rigidity ring composition and cast aluminum shell employed Hoisting, derric ept limiting stopper to extend support existence.



seven.Massive constructions as mast segment, turn capable, top kit and hoisting jib adopt superior equipment as NC machine resource, drilling equipment, milling machine processing soon after welding. That effectively guarantees merchandise assembly accuracy, minimizing the failure rate and enhancing the protection.


eight.twelve computerized spraying assembly line, the whole device adopt impeller blasting to make certain the cleanliness of metal surface area and eliminate the internal anxiety creating in welding process, increase the toughness and metal surface hardness, enhance painting adhesion. Two primer, a paint spraying technologies, gorgeous visual appeal, corrosion resistance has elevated much more than 2 times than thTorque limiters are mechanical and electromechanical energy-transmission units that defend device sections (or workpieces they’re servicing) from overloads, crashes, and harm from jams.e life of regular spraying method. System, the modest vehicle, fence and other tiny items adopt very hot dip galvanized soon after acid phosphate treatment, rust resistance more powerful.


nine.Hoisting, derric ept and slewing mechanism, with complete protection these kinds of as torque, bodyweight restrict. The metal wire rope broken rope system. Assortment of the vehicle style towards reduction and broken shaft, this sort of as tilting unit. The electrical adopts overload protection, the style of PLC self-analysis method, it truly is convenient to maintenance.



10.Dahan three manufacturing bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to much more than 50 international locations and areas. We have more than a thousand sets following-revenue services network. We carried out the earliest stagnation position support method in this tower crane ept that ensure the high quality of service and performance. Otherwise, better to take away customer’s problems.
