The ten benefits of DaHan tower crane 

  1. With 56,000 sets of marketplace volume and exceptional status, EPT tower crane ranks the initial location in China tower crane ept in the past many years. EPT always adheres to the benefit that source the most valuable tower crane and provider for the customer, with the greatest value performance in the market. 



two. EPT tower crane owns the foremost technological innovation R&D team, the product top quality passed several experiments with stringent tests. Or else, EPT has 16 many years of production technology and prosperous encounters in top quality management. Till now, more than 100 nationwide technology patents of tower crane have been place into use previously.


3.In buy to assure the dependability of tower crane good quality and reduce the cost, all raw components are directly equipped by renowned makes like Baosteel and Wisco. Uncooked materials for principal parts this kind of as standard segment principal limbs, tower caps undertake Q345B steel, as a result the tensile power enhanced by thirty% and the tower crane gets to be a lot more secure and reliable. 


4.Dahan tower crane is the enterprise which firstly commenced to use the robot welding strains. At current, we have a fully automated robot welding creation line for mast sections fabrication created up by more than a hundred welding robots. The production line is composed with automatic materials preparing, welding and maching. All major components of Dahan tower crane use robotic welding, with the most ept carbon dioxide blended with argon fuel shielded welding, it has deep depth of fusion, high quality of welding and stable performance.


five. All elements and parts of EPT tower crane use top quality makes. Electric gear with Schneider converter, aviation plug, stainless steel distribution box and 3 linkage console has characteristics of reduced failure price and simple set up.
Hoisting system is supplied by major producer Jiangte Motor or HangZhou Shengjian, all with motor oil, totally free upkeep, substantial dependability and minimal servicing price.
Slewing support utilizes HangZhou Fangyuan brand or Rothe Erde manufacturer, two times tempering processing makes far more efficiently operation and longer tower crane service existence.


6. Focus to element high quality.  High-energy bolt adopt shipborne scale DACROMET technological innovation. It can hold not rusted for 10 several years .Swiss screw-thread bolts of preload promote thirty percent than conventional bolts. Bodyweight limiter makes use of the stress ring structure and cast aluminum shell used Hoisting, derric ept restricting stopper to extend support lifestyle.



seven.Massive buildings as mast segment, flip in a position, prime package and hoisting jib undertake superior gear as NC equipment resource, drilling machine, milling equipment processing following welding. That efficiently assures items assembly accuracy, reducing the failure charge and improving the security.


8.12 automatic spraying assembly line, the complete machine undertake impeller blasting to guarantee the cleanliness of steel area and eradicate the interior tension producing in welding procedure, increase the toughness and metal surface area hardness, enhance painting adhesion. Two primer, a paint spraying technologies, beautiful appearance, corrosion resistance has increased more than 2 times than the existence of regular spraying approach. Platform, the small automobile, fence and other small parts undertake hot dip galvanized following acid phosphate treatment, rust resistance more robust.


9.Hoisting, derric ept and slewing mechanism, with full security these kinds of as torque, excess weight restrict. The steel wire rope broken rope gadget. Assortment of the automobile style against reduction and broken shaft, this sort of as tilting unit. The electrical adopts overload protection, the style of PLC self-diagnosis technique, it’s handy to servicing.



10.Dahan three creation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to a lot more than 50 nations around the world and locations. We have much more than 1000 sets following-sales provider network. We carried out the earliest stagnation stage support manner in this tower crane ept that guarantee the good quality of support and effectiveness. Otherwise, better to take away customer’s problems.

Right after your choiceBall-detent torque limiters transmit pressure by way of arrays of balls locked (by springs) in detents. These one or multi-situation torque limiters clutch connected load by permitting the balls escape their detents when drive torque exceeds that to overcome the spring established. Roller-detent torque limiters perform considerably the same way as ball-detent types — by wedging among the torque limiter’s internal and outer races. These torque limiters can call for manual reset, or they can reset automatically. If a multi-position design, detents are spaced every single thirty, sixty, 90° or other interval to serve slow-speed axes that can not tolerate a lengthy sluggish wait around for reengagement
