The 10 benefits of DaHan tower crane 

  1. With 56,000 sets of marketplace quantity and outstanding status, EPT tower crane ranks the first area in China tower crane ept in the previous many years. EPT often adheres to the benefit that supply the most valuable tower crane and support for the client, with the greatest value overall performance in the market. 


2. EPT tower crane owns the leading technology R&D staff, the merchandise quality handed a number of experiments with rigorous screening. In any other case, EPT has 16 years of creation technological innovation and wealthy encounters in quality management. Till now, over 100 nationwide technological innovation patents of tower crane have been putBall-detent torque limiters transmit pressure by way of arrays of balls locked (by springs) in detents. These solitary or multi-position torque limiters clutch connected load by permitting the balls escape their detents when travel torque exceeds that to get over the spring established. Roller-detent torque limiters perform much the exact same way as ball-detent versions — by wedging in between the torque limiter’s internal and outer races. These torque limiters can call for guide reset, or they can reset instantly. If a multi-situation product, detents are spaced each and every 30, sixty, 90° or other interval to serve sluggish-speed axes that simply cannot tolerate a long gradual hold out for reengagement into use presently.

3.In get to assure the trustworthiness of tower crane quality and lessen the price, all uncooked materials are right provided by famous brands like Baosteel and Wisco. Raw supplies for major parts such as common part main limbs, tower caps undertake Q345B steel, as a result the tensile toughness enhanced by 30% and the tower crane gets more safe and trustworthy. 

four.Dahan tower crane is the enterprise which first of all started to use the robot welding lines. At present, we have a fully computerized robot welding production line for mast sections fabrication created up by much more than a hundred welding robots. The generation line is composed with automatic material planning, welding and maching. All major components of Dahan tower crane use robotic welding, with the most ept carbon dioxide blended with argon gasoline shielded welding, it has deep depth of fusion, substantial good quality of welding and secure overall performance.


five. All parts and factors of EPT tower crane use high quality brand names. Electric gear with Schneider converter, aviation plug, stainless steel distribution box and three linkage console has functions of reduced failure charge and straightforward installation.
Hoisting system is supplied by leading maker Jiangte Motor or HangZhou Shengjian, all with motor oil, totally free routine maintenance, substantial trustworthiness and lower servicing charge.
Slewing help utilizes HangZhou Fangyuan model or Rothe Erde model, two times tempering processing tends to make more easily operation and for a longer time tower crane services life.


6. Attention to element high quality.  High-toughness bolt undertake shipborne scale DACROMET technological innovation. It can maintain not rusted for ten a long time .Swiss screw-thread bolts of preload promote 30 % than traditional bolts. Excess weight limiter makes use of the tension ring construction and cast aluminum shell utilized Hoisting, derric ept limiting stopper to lengthen service lifestyle.

seven.Huge structures as mast segment, flip in a position, top package and hoisting jib adopt innovative equipment as NC equipment instrument, drilling machine, milling machine processing right after welding. That effectively assures items assembly precision, decreasing the failure fee and enhancing the protection.


8.twelve computerized spraying assembly line, the whole device undertake impeller blasting to make sure the cleanliness of steel floor and get rid of the internal stress creating in welding procedure, improve the strength and metal surface area hardness, increase painting adhesion. Two primer, a paint spraying engineering, stunning appearance, corrosion resistance has elevated more than two times than the lifestyle of common spraying procedure. System, the tiny auto, fence and other modest parts undertake hot dip galvanized after acid phosphate therapy, rust resistance more robust.


9.Hoisting, derric ept and slewing mechanism, with complete basic safety such as torque, weight restrict. The metal wire rope broken rope unit. Variety of the auto layout towards reduction and broken shaft, such as tilting unit. The electrical adopts overload protection, the design and style of PLC self-diagnosis program, it is handy to maintenance.

ten.Dahan three production bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to far more than 50 countries and areas. We have a lot more than a thousand sets after-sales provider community. We carried out the earliest stagnation stage services manner in this tower crane ept that ensure the good quality of services and performance. Otherwise, better to take away customer’s problems.
