The 10 positive aspects of DaHan tower crane 

  1. With 56,000 sets of market quantity and exceptional track record, EPT tower crane ranks the first place in China tower crane ept in the previous a long time. EPT constantly adheres to the value that provide the most useful tower crane and services for the customerFriction-disc torque limiters use friction contact amongst mating discs to transmit energy — and operate a lot like friction-disc clutches in that overloads result in slipping in between the discs. Friction-disc torque limiters excel in purposes necessitating continuous operating and average adherence to a protected-torque placing for safety. When mounted on to motor-driven machines, these torque limiters let axes to power by means of partial jams using motor inertia to carry on application of torque. That prevents nuisance stops throughout momentary load boosts … although in the course of true overloads and inertial shock loading, the torque limiter slips repeatedly to protect the system from injury., with the greatest value functionality in the industry. 



2. EPT tower crane owns the leading technological innovation R&D staff, the product high quality passed numerous experiments with strict testing. Otherwise, EPT has 16 many years of creation technology and wealthy encounters in high quality management. Till now, in excess of 100 national technology patents of tower crane have been put into use presently.


three.In order to promise the reliability of tower crane quality and reduce the price, all raw supplies are straight provided by popular brands like Baosteel and Wisco. Uncooked components for main parts these kinds of as normal part principal limbs, tower caps adopt Q345B metal, as a result the tensile energy increased by thirty% and the tower crane gets to be much more risk-free and trustworthy. 


4.Dahan tower crane is the company which firstly began to use the robot welding traces. At current, we have a fully automated robotic welding generation line for mast sections fabrication manufactured up by far more than one hundred welding robots. The generation line is composed with computerized substance preparing, welding and maching. All major components of Dahan tower crane use robot welding, with the most ept carbon dioxide mixed with argon gasoline shielded welding, it has deep depth of fusion, substantial quality of welding and stable efficiency.


five. All areas and parts of EPT tower crane use high quality brands. Electrical products with Schneider converter, aviation plug, stainless metal distribution box and 3 linkage console has attributes of minimal failure fee and easy set up.
Hoisting system is presented by leading manufacturer Jiangte Motor or HangZhou Shengjian, all with engine oil, free of charge servicing, higher trustworthiness and minimal maintenance fee.
Slewing support makes use of HangZhou Fangyuan brand name or Rothe Erde manufacturer, twice tempering processing makes more efficiently operation and longer tower crane provider existence.


six. Attention to depth high quality.  High-strength bolt adopt shipborne scale DACROMET technological innovation. It can hold not rusted for 10 several years .Swiss screw-thread bolts of preload market thirty p.c than traditional bolts. Weight limiter makes use of the tension ring structure and forged aluminum shell employed Hoisting, derric ept restricting stopper to lengthen services lifestyle.



7.Large structures as mast section, flip able, leading package and hoisting jib undertake sophisticated tools as NC device tool, drilling device, milling device processing after welding. That efficiently assures merchandise assembly accuracy, reducing the failure price and improving the safety.


eight.twelve automatic spraying assembly line, the complete device adopt impeller blasting to guarantee the cleanliness of steel area and eradicate the interior pressure making in welding method, increase the strength and metal floor hardness, improve painting adhesion. Two primer, a paint spraying technologies, gorgeous visual appeal, corrosion resistance has increased a lot more than 2 times than the lifestyle of ordinary spraying procedure. System, the modest auto, fence and other modest pieces undertake very hot dip galvanized following acid phosphate remedy, rust resistance more powerful.


9.Hoisting, derric ept and slewing system, with full security these kinds of as torque, fat restrict. The metal wire rope broken rope unit. Variety of the auto style in opposition to reduction and damaged shaft, this kind of as tilting unit. The electrical adopts overload protection, the design and style of PLC self-diagnosis program, it truly is practical to maintenance.



10.Dahan three creation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to a lot more than fifty nations and areas. We have far more than one thousand sets following-revenue support community. We carried out the earliest stagnation stage service method in this tower crane ept that make certain the quality of service and performance. Otherwise, better to get rid of customer’s problems.
