The 10 rewards of DaHan tower crane 

  1. With 56,000 sets of market volume and excellent popularity, EPT tower crane ranks the 1st spot in China tower crane ept in the previous a long time. EPT constantly adheres to the value that provide the most beneficial tower crane and support for the client, with the maximum expense performance in the sector. 


2. EPT tower crane owns the top technologies R&D crew, the item quality passed several experiments with strict testing. Normally, EPT has sixteen a long time of production technology and abundant experiences in high quality administration. Till now, over one hundred countrywide engineering patents of tower crane have been put into use previously.

three.In order to ensure the dependability of tower crane high quality and minimize the cost, all raw resources are right supplied by renowned brands like Baosteel and Wisco. Uncooked materials for primary parts this kind of as normal section principal limbs, tower caps undertake Q345B metal, hence the tensile energy elevated by thirty% and the tower crane turns into a lot more secure and reliable. 

four. EPT tower crane is the enterprise which firstly began to use the robotic welding traces. At current, we have a fully automated robotic welding production line for mast sections fabrication madThe torque limiter is employed to few two separate bodies of rotation. The two individual bodies may consist of shafts, gears, sprockets, a prime mover or motor, or any combination of these. The elements are typically pumps, fans, Energy Takeoffs, compressors, motors, gearboxes and turbines, but it is typically the shaft of the ingredient by itself that is employed to transfer power whether or not a pushed or driving factor.e up by far more than a hundred welding robots. The manufacturing line is composed with automated content planning, welding and maching. All primary elements of EPT tower crane use robotic welding, with the most ept carbon dioxide mixed with argon gas shielded welding, it has deep depth of fusion, large good quality of welding and secure overall performance.


five. All elements and elements of EPT tower crane use premium manufacturers. Electrical gear with Schneider converter, aviation plug, stainless steel distribution box and a few linkage console has features of minimal failure fee and easy installation.
Hoisting mechanism is presented by major manufacturer Jiangte Motor or HangZhou Shengjian, all with engine oil, cost-free upkeep, higher dependability and minimal servicing rate.
Slewing support utilizes HangZhou Fangyuan model or Rothe Erde model, twice tempering processing tends to make a lot more efficiently operation and more time tower crane service lifestyle.


6. Attention to depth top quality.  High-power bolt adopt shipborne scale DACROMET technology. It can maintain not rusted for ten years .Swiss screw-thread bolts of preload promote thirty % than standard bolts. Bodyweight limiter uses the stress ring structure and forged aluminum shell used Hoisting, derric ept limiting stopper to lengthen services existence.


seven.Huge constructions as mast part, change ready, leading kit and hoisting jib undertake advanced equipment as NC device instrument, drilling machine, milling device processing following welding. That properly assures items assembly accuracy, decreasing the failure price and improving the safety.

eight.12 automated spraying assembly line, the total device undertake impeller blasting to make certain the cleanliness of steel surface area and remove the inner anxiety creating in welding approach, increase the power and steel floor hardness, increase portray adhesion. Two primer, a paint spraying engineering, lovely visual appeal, corrosion resistance has enhanced a lot more than twice than the lifestyle of normal spraying procedure. System, the tiny auto, fence and other tiny parts undertake very hot dip galvanized following acid phosphate treatment method, rust resistance more powerful.


9.Hoisting, derric ept and slewing system, with full safety this kind of as torque, bodyweight limit. The steel wire rope damaged rope gadget. Assortment of the car layout against reduction and damaged shaft, this sort of as tilting device. The electrical adopts overload protection, the style of PLC self-diagnosis system, it’s handy to servicing.


10. EPT 3 generation bases is ZheJiang , ZheJiang , ZheJiang . EPT tower crane are exported to much more than 50 nations around the world and regions. We have a lot more than one thousand sets right after-sales support network. We carried out the earliest stagnation position support method in this tower crane ept that make certain the high quality of provider and efficiency. In any other case, better to eliminate customer’s worries.
