The ten positive aspects of DaHan tower crane 

  1. With fifty six,000 sets of marketplace volume and superb track record, EPT tower crane ranks the very first spot in China tower crane ept in the previous decades. EPT constantly adheres to the benefit that offer the most useful tower crane and support for the consumer, with the greatest value performance in the business. 


2. EPT tower crane owns the foremost technology R&D team, the merchandise quality passed several experiments with strict testing. Or else, EPT has 16 years of production technologies and wealthy ordeals in good quality administration. Till now, over 100 national technology patents of tower crane have been put into use currently.

3.In get to assure the reliability of tower crane top quality and reduce the expense, all raw resources are right equipped by well-known brands like Baosteel and Wisco. Raw materials for major components such as standard segment main limbs, tower caps undertake Q345B steel, thus the tensile energy elevated by 30% and the tower crane gets to be a lot more safe and reputable. 

4. EPT tower crane is the organization which firstly started to use the robot welding strains. At present, we have a fully computerized robotic welding creation line for mast sections fabrication produced up by a lot more than a hundred welding robots. The manufacturing line is composed with automated material preparing, welding and maching. All main elements of EPT tower crane use robotic welding, wiBall-detent torque limiters transmit drive via arrays of balls locked (by springs) in detents. These one or multi-placement torque limiters clutch connected load by allowing the balls escape their detents when push torque exceeds that to conquer the spring set. Roller-detent torque limiters perform considerably the very same way as ball-detent versions — by wedging between the torque limiter’s interior and outer races. These torque limiters can call for manual reset, or they can reset immediately. If a multi-position product, detents are spaced each thirty, sixty, 90° or other interval to serve gradual-speed axes that cannot tolerate a prolonged gradual wait around for reengagementth the most ept carbon dioxide combined with argon gasoline shielded welding, it has deep depth of fusion, large high quality of welding and stable overall performance.


five. All elements and elements of EPT tower crane use quality brands. Electric powered tools with Schneider converter, aviation plug, stainless steel distribution box and a few linkage console has characteristics of reduced failure price and easy installation.
Hoisting system is presented by top maker Jiangte Motor or HangZhou Shengjian, all with motor oil, free routine maintenance, substantial trustworthiness and lower upkeep price.
Slewing support uses HangZhou Fangyuan manufacturer or Rothe Erde brand name, two times tempering processing can make a lot more efficiently operation and longer tower crane services life.


6. Interest to depth quality.  High-toughness bolt undertake shipborne scale DACROMET technologies. It can maintain not rusted for ten many years .Swiss screw-thread bolts of preload promote 30 per cent than conventional bolts. Weight limiter utilizes the stress ring construction and solid aluminum shell used Hoisting, derric ept restricting stopper to lengthen provider existence.


7.Big structures as mast section, flip ready, prime kit and hoisting jib adopt sophisticated gear as NC equipment resource, drilling device, milling machine processing after welding. That successfully guarantees goods assembly precision, reducing the failure price and bettering the stability.

8.12 computerized spraying assembly line, the entire machine undertake impeller blasting to make certain the cleanliness of metal floor and eliminate the internal anxiety making in welding method, increase the toughness and steel surface area hardness, boost painting adhesion. Two primer, a paint spraying engineering, stunning physical appearance, corrosion resistance has increased a lot more than twice than the life of regular spraying procedure. System, the little car, fence and other little parts undertake scorching dip galvanized following acid phosphate remedy, rust resistance stronger.


9.Hoisting, derric ept and slewing system, with complete safety this kind of as torque, bodyweight restrict. The steel wire rope damaged rope device. Variety of the vehicle design and style from loss and broken shaft, such as tilting gadget. The electrical adopts overload security, the style of PLC self-analysis system, it’s handy to maintenance.


10. EPT 3 generation 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 right after-product sales support network. We carried out the earliest stagnation level service mode in this tower crane ept that ensure the quality of provider and effectiveness. In any other case, much better to get rid of customer’s concerns.
