The 10 advantages of DaHan tower crane 

  1. With 56,000 sets of industry volume and superb status, EPT tower crane ranks the 1st area in China tower crane ept in the earlier a long time. EPT always adheres to the price that source the most worthwhile tower crane and service for the consumer, with the maximum value performance in the business. 


2. EPT tower crane owns the foremost technologies R&D crew, the item quality handed numerous experiments with stringent testing. Or else, EPT has 16 a long time of production technologies and wealthy ordeals in high quality administration. Till now, above a hundred nationwide technologies patents of tower crane have been set into use previously.

3.In get to guarantee the dependability of tower crane quality and minimize the value, all uncooked components are directly provided by well-known manufacturers like Baosteel and Wisco. Raw materials for primary areas this kind of as regular section major limbs, tower caps adopt Q345B metal, therefore the tensile power improved by 30% and the tower crane becomes far more protected and reputable. 

four.Dahan tower crane is the enterprise which first of all began to use the robot welding liUPON OVERLOAD Throughout a torque overload, such as in the scenario of a jam preventing rotation of the output members, the stress utilized by the DISC SPRING is get over and the output associates slip which stops a spike in torque from transmitting to the input part.nes. At present, we have a fully computerized robotic welding production line for mast sections fabrication made up by much more than a hundred welding robots. The generation line is composed with automated substance preparation, welding and maching. All main elements of Dahan tower crane use robotic welding, with the most ept carbon dioxide mixed with argon gas shielded welding, it has deep depth of fusion, high quality of welding and secure efficiency.


five. All parts and components of EPT tower crane use top quality manufacturers. Electric equipment with Schneider converter, aviation plug, stainless steel distribution box and 3 linkage console has characteristics of lower failure rate and simple set up.
Hoisting mechanism is offered by foremost company Jiangte Motor or HangZhou Shengjian, all with engine oil, totally free servicing, high dependability and low maintenance charge.
Slewing support makes use of HangZhou Fangyuan manufacturer or Rothe Erde brand, twice tempering processing helps make more efficiently operation and longer tower crane provider lifestyle.


6. Attention to detail good quality.  High-strength bolt adopt shipborne scale DACROMET technology. It can hold not rusted for 10 several years .Swiss screw-thread bolts of preload promote thirty percent than traditional bolts. Weight limiter utilizes the stress ring composition and cast aluminum shell utilized Hoisting, derric ept limiting stopper to prolong services existence.

seven.Large buildings as mast part, switch ready, leading kit and hoisting jib undertake sophisticated products as NC equipment device, drilling machine, milling machine processing soon after welding. That efficiently assures goods assembly precision, decreasing the failure fee and bettering the safety.


8.12 automatic spraying assembly line, the entire device undertake impeller blasting to ensure the cleanliness of steel surface area and get rid of the inside pressure creating in welding process, boost the energy and steel surface area hardness, boost portray adhesion. Two primer, a paint spraying engineering, stunning look, corrosion resistance has elevated a lot more than twice than the existence of common spraying procedure. Platform, the modest automobile, fence and other tiny pieces undertake scorching dip galvanized following acid phosphate remedy, rust resistance stronger.


nine.Hoisting, derric ept and slewing mechanism, with total safety this sort of as torque, fat limit. The metal wire rope broken rope system. Assortment of the car style against reduction and damaged shaft, this kind of as tilting device. The electrical adopts overload protection, the layout of PLC self-prognosis system, it truly is convenient to upkeep.

10.Dahan three production bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to more than 50 nations and areas. We have much more than 1000 sets following-product sales support community. We carried out the earliest stagnation point support method in this tower crane ept that guarantee the quality of support and efficiency. Otherwise, better to eliminate customer’s concerns.
