The ten positive aspects of DaHan tower crane 

  1. With 56,000 sets of market place quantity and outstanding status, EPT tower crane ranks the very first area in China tower crane ept in the previous decades. EPT always adheres to the value that source the most worthwhile tower crane and provider for the client, with the optimum expense efficiency in the market. 



2. EPT tower crane owns the major technologies R&D group, the item quality passed a number of experiments with rigid tests. Or else, EPT has sixteen many years of manufacturing technological innovation and abundant ordeals in top quality management. Until now, above a hundred nationwide engineering patents of tower crane have been set into use previously.


three.In order to assure the trustworthiness of tower crane good quality and decrease the expense, all raw components are right equipped by well-known brands like Baosteel and Wisco. Raw resources for main elements this sort of as regular area major limbs, tower caps adopt Q345B metal, as a result the tensile strength increased by thirty% and the tower crane turns into a lot more secure and trustworthy. 


4.Dahan tower crane is the organization which first of all started to use the robot welding strains. At existing, we have a fully automated robot welding creation line for mast sections fabrication manufactured up by more than 100 welding robots. The creation line is composed with computerized material planning, welding and maching. All main elements of Dahan tower crane use robotic welding, with the most ept carbon dioxide combined with argon fuel shielded welding, it has deep depth of fusion, high high quality of welding and secure overall performance.


5. All parts and parts of EPT tower crane use high quality brands. Electric tools with Schneider converter, aviation plug, stainless steel distribution box and a few linkage console has attributes of low failure rate and easy installation.
Hoisting mechanism is presented by leading producer Jiangte Motor or HangZhou Shengjian, all with engine oil, free routine maintenance, substantial reliaRotating methods can have sufficient rotating vitality (inertia) to result in considerable machine harm for the duration of a jam-up or method crash. This inertia may differ primarily based on the RPM and rotating mass for each and every application. A high mass gradual velocity (RPM) could do much more injury than a large pace software throughout a crash. A torque limiter is essentially a mechanical fuse utilized to shut down the device and let the rotating vitality to dissipate without having creating abnormal harm.bility and low servicing rate.
Slewing assist utilizes HangZhou Fangyuan brand or Rothe Erde model, two times tempering processing makes far more easily procedure and more time tower crane support daily life.


six. Attention to detail high quality.  High-energy bolt adopt shipborne scale DACROMET technologies. It can hold not rusted for ten a long time .Swiss screw-thread bolts of preload advertise 30 p.c than traditional bolts. Weight limiter utilizes the rigidity ring framework and forged aluminum shell utilized Hoisting, derric ept limiting stopper to extend service daily life.



seven.Massive buildings as mast area, switch in a position, prime package and hoisting jib adopt superior equipment as NC machine tool, drilling equipment, milling device processing following welding. That successfully assures items assembly precision, decreasing the failure price and improving the safety.


eight.twelve automated spraying assembly line, the complete equipment undertake impeller blasting to make sure the cleanliness of steel area and eliminate the interior anxiety creating in welding process, increase the power and metal floor hardness, improve portray adhesion. Two primer, a paint spraying technology, beautiful appearance, corrosion resistance has enhanced more than two times than the lifestyle of regular spraying procedure. System, the modest automobile, fence and other modest pieces undertake scorching dip galvanized right after acid phosphate treatment, rust resistance more robust.


nine.Hoisting, derric ept and slewing mechanism, with complete protection this kind of as torque, fat restrict. The metal wire rope broken rope device. Assortment of the car style towards loss and damaged shaft, this sort of as tilting gadget. The electrical adopts overload safety, the style of PLC self-analysis method, it really is practical to maintenance.



10.Dahan three production bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to more than fifty international locations and areas. We have more than a thousand sets after-income support community. We carried out the earliest stagnation point services manner in this tower crane ept that guarantee the high quality of support and performance. Otherwise, better to take away customer’s problems.
