The 10 rewards of DaHan tower crane 

  1. With fifty six,000 sets of industry quantity and outstanding reputation, EPT tower crane ranks the very first place in China tower crane ept in the previous decades. EPT always adheres to the value that provide the most useful tower crane and provider for the customer, with the maximum value performance in the sector. 


two. EPT tower crane owns the leading engineering R&D staff, the solution high quality passed a number of experiments with strict testing. In any other case, EPT has 16 years of generation technology and wealthy activities in top quality management. Till now, over one hundred national technologies patents of tower crane have been set into use presently.

three.In purchase to promise the reliability of tower crane high quality and minimize the value, all raw resources are directly supplied by popular brands like Baosteel and Wisco. Uncooked materials for principal parts these kinds of as common part principal limbs, tower caps undertake Q345B metal, therefore the tensile strength improved by 30% and the tower crane gets far more secure and reliable. 

4. EPT tower crane is the business which to start with started out to use the robotic welding strains. At present, we have a fully automated robotic welding manufacturing line for mast sections fabrication made up by more than one hundred welding robots. The manufacturing line is composed with computerized materials planning, welding and maching. All major parts of EPT 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 steady efficiency.


five. All components and elements of EPT tower crane use high quality brand names. Electrical equipment with Schneider converter, aviation plug, stainless metal distribution box and three linkage console has attributes of lower failure charge and easy set up.
Hoisting system is supplied by foremost producer Jiangte Motor or HangZhou Shengjian, all with engine oil, cost-free maintenance, substantial dependability and lower routine maintenance charge.
Slewing support utilizes HangZhou Fangyuan brand or Rothe Erde manufacturer, twice tempering processing tends to make far more smoothly operation and more time tower crane service existence.


6. Attention to detail quality.  High-energy bolt adopt shipborne scale DACROMET technologies. It can preserve not rusted for 10 a long time .Swiss screw-thread bolts of preload advertise 30 percent than conventional bolts. Excess weight limiter employs the stress ring framework and solid aluminum shell utilized Hoisting, derric ept limiting stopper to prolong support existence.


seven.Massive buildings as mast part, change in a position, best package and hoisting jib adopt sophisticated products as NC equipment tool, drilling machine, milling device processing soon after welding. That successfully guarantees items assembly precision, reducing the failure price and strengthening the security.

eight.12 computerized spraying assembly line, the entire equipment adopt impeller blasting to ensure the cleanliness of metal floor and eliminate the inner anxiety creating in welding approach, increase the energy and metal surface hardness, enhance painting adhesion. Two primer, a paint spraying technological innovation, gorgeous visual appeal, corrosion resistance has elevated much more than two times than the existence of ordinary spraying approach. Platform, the modest auto, fence and other modest items undertake sizzling dip galvanized soon after acid phosphate remedy, rust resistance stronger.


nine.Hoisting, derric ept and slewing system, with comprehensive basic safety this kind of as torque, excess weight limit. The metal wire rope damaged rope unit. Range of the vehicle style towards loss and damaged shaft, these kinds of as tilting device. The electrical adopts overload safety, the style of PLC self-analysis technique, it truly is practical to maintenance.


10. EPT 3 creation bases is ZheJiang , ZheJiang , ZheJiang . EPT tower crane are exported to much more than 50 countries and areas. We have far more than one thousand sets following-product sales support network. We carried out the earliest stagnation level service method in this tower crane ept that ensure the good quality of services and efficiency. In any other case, much better to take away customer’s anxieties.
