The ten benefits of DaHan tower crane 

  1. With 56,000 sets of market quantity and superb popularity, EPT tower crane ranks the very first area in China tower crane ept in the past decades. EPT constantly adheres to the benefit that supply the most valuable tower crane and service for the consumer, with the greatest expense efficiency in the industry. 


2. EPT tower crane owns the foremost technological innovation R&D team, the solution high quality passed a number of experiments with rigorous tests. Normally, EPT has sixteen several years of creation technology and prosperous activities in good quality management. Till now, above a hundred national technologies patents of tower crane have been set into use previously.

three.In order to assure the trustworthiness of tower crane quality and reduce the value, all uncooked materials are straight provided by famous makes like Baosteel and Wisco. Raw materials for main parts these kinds of as common section major limbs, tower caps adopt Q345B metal, thus the tensile energy increased by 30% and the tower crane gets to be far more protected and reputable. 

4. EPT tower crane is the company which to start with started to use the robotic welding traces. At current, we have a fully computerized robotic welding creation line for mast sections fabrication created up by more than a hundred welding robots. The creation line is composed with computerized content preparing, welding and maching. All main elements of EPT tower crane use robot welding, with the most ept carbon dioxide mixed with argon fuel shielded welding, it has deep depth of fusion, high high quality of welding and stable efficiency.


5. All components and components of EPT tower crane use high quality makes. Electric equipment with Schneider converter, aviation plug, stainless metal distribution box and 3 linkage console has characteristics of reduced failure price and easy set up.
Hoisting mechanism is supplied by foremost producer Jiangte Motor or HangZhou Shengjian, all with motor oil, cost-free routine maintenance, high dependability and reduced servicing charge.
Slewing assist makes use of HangZhou Fangyuan brand or Rothe Erde manufacturer, twice tempering processing makes far more efficiently procedure and lengthier tower crane service daily life.


6. Interest to detail good quality.  High-energy bolt adopt shipborne scale DACROMET engineering. It can preserve not rusted for 10 several years .Swiss screw-thread bolts of preload advertise thirty % than conventional bolts. Excess weight limiter uses the stress ring construction and cast aluminum shell used Hoisting, derric ept restricting stopper to increase services life.


7.Large buildings as mast section, flip ready, leading kit and hoisting jib undertake superior tools as NC equipment resource, drilling machine, milling equipment processing soon after welding. That effectively assures merchandise assembly precision, minimizing the failure charge and bettering the protection.

8.twelve computerized spraying assembly line, the whole machine adopt impeller blasting to ensure the cleanliness of metal floor and eradicate the internal stress creating in welding approach, improve the power and steel area hardness, increase painting adhesion. Two primer, a paint spraying technology, gorgeous physical appearance, corrosion resistance has improved much more than 2 times than the life of common spraying approach. Platform, the small auto, fence and other tiny pieces undertake very hot dip galvanized after acid phosphate therapy, rust resistance much better.


nine.Hoisting, derric ept and slewing system, with comprehensive basic safety this kind of as torque, weight limit. The metal wire rope broken rope device. Range of the auto design towards loss and broken shaft, this kind of as tilting gadget. The electrical adopts overload defense, the style of PLC self-prognosis program, it truly is handy to routine maintenance.


10. EPT a few manufacturing bases is ZheJiang , ZheJiang , ZheJiang . EPT tower crane are exported to far more than fifty countries and areas. We have a lot more than a thousand sets soon after-product sales support community. We carried out the earliest stagnation level service method in this toThe Torq-Tender torque limiter is tamper-proof. As soon as mounted, the torque value can not be transformed. This characteristic ensures the integrity of the machined style, and renders high priced and possibly risky calibration procedures needless. Torque price is managed by the component quantity that is purchased that benefit decides what spring is utilized in the course of assembly of the torque limiter.wer crane ept that make sure the quality of provider and effectiveness. Otherwise, far better to remove customer’s problems.
