The ten advantages of DaHan tower crane 

  1. With 56,000 sets of market place volume and superb popularity, EPT tower crane ranks the initial place in China tower crane ept in the previous decades. EPT usually adheres to the value that supply the most worthwhile tower crane and support for the customer, with the greatest cost functionality in the sector. 



2. EPT tower crane owns the major technology R&D team, the solution top quality passed several experiments with rigid tests. In any other case, EPT has sixteen several years of manufacturing technology and wealthy encounters in high quality administration. Till now, above 100 countrywide technology patents of tower crane have been place into use currently.


3.In purchase to ensure the reliability of tower crane top quality and reduce the value, all uncooked materials are straight provided by renowned makes like Baosteel and Wisco. Uncooked materials for main components such as common part primary limbs, tower caps adopt Q345B metal, as a result the tensile power enhanced by thirty% and the tower crane gets to be more safe and reliable. 


four.Dahan tower crane is the organization which to start with began to use the robot welding strains. At current, we have a fully automated robotic welding manufacturing line for mast sections fabrication created up by far more than 100 welding robots. The manufacturing line is composed with automated content planning, welding and maching. All primary elements of Dahan tower crane use robotic welding, with the most ept carbon dioxide combined with argon gas shielded welding, it has deep depth of fusion, higher good quality of welding and stable efficiency.


5. All areas and factors of EPT tower crane use top quality brands. Electric products with Schneider converter, aviation plug, stainless steel distribution box and 3 linkage console has attributes of reduced failure rate and straightforward installation.
Hoisting mechanism is provided by foremost manufacturer Jiangte Motor or HangZhou Shengjian, all with motor oil, free servicing, substantial trustworthiness and minimal maintenance rate.
Slewing support uses HangZhou Fangyuan brand or Rothe Erde manufacturer, 2 times tempering processing makes much more easily operation and for a longer time tower crane services daily life.


six. Focus to depth good quality.  High-strength bolt undertake shipborne scale DACROMET technology. It can hold not rusted for 10 many years .Swiss screw-thread bolts of preload encourage 30 p.c than classic bolts. Bodyweight limiter uses the stress ring composition and cast aluminum shell utilised Hoisting, derric ept restricting stopper to increase services existence.



7.Big constructions as mast area, switch capable, best kit and hoisting jib undertake advanced products as NC machine tool, drilling equipment, milling device processing right after welding. That properly guarantees products assembly accuracy, decreasing the failure fee and bettering the protection.


8.12 computerized spraying assembly line, the whole machine adopt impeller blasting to make certain the cleanliness of metal area and eliminate the inside tension making in welding approach, improve the energy and metal surface area hardness, boost portray adhesion. Two primer, a paint spraying engineering, stunning look, corrosion resistance has elevated far more than two times than the existence of ordinary spraying approach. Platform, the modest vehicle, fence and other little items adopt scorching dip galvanized soon after acid phosphate therapy, rus400 Series The 400 Collection has been made to satisfy the need to have for a high-and lower-pace, free of charge-wheeling torque limiter. It differs from earlier ball detent patterns by using two sets of balls on concentric pitch circles.t resistance more robust.


9.Hoisting, derric ept and slewing mechanism, with comprehensive safety these kinds of as torque, bodyweight restrict. The steel wire rope broken rope unit. Range of the automobile design and style against reduction and damaged shaft, these kinds of as tilting device. The electrical adopts overload security, the design and style of PLC self-analysis system, it’s convenient to upkeep.



10.Dahan three generation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to much more than 50 international locations and regions. We have a lot more than one thousand sets after-revenue support network. We carried out the earliest stagnation point provider mode in this tower crane ept that make certain the good quality of services and effectiveness. Otherwise, better to remove customer’s concerns.
