The 10 advantages of DaHan tower crane 

  1. With fifty six,000 sets of marketplace quantity and exceptional status, EPT towerStandard Torq-Tenders are bidirectional. Torque worth stays the same regardless of rotation. If specified, the torque limiter can be configured at the manufacturing unit to release at diverse torque scores for distinct rotational instructions. When utilised as a coupling, the Torq-Tender fulfills two functions: 1) A flexible shaft coupling 2) a mechanical torque limiter. crane ranks the very first spot in China tower crane ept in the past many years. EPT always adheres to the price that supply the most useful tower crane and support for the customer, with the optimum price overall performance in the industry. 


2. EPT tower crane owns the top technological innovation R&D group, the merchandise good quality handed many experiments with strict testing. Normally, EPT has 16 years of generation technologies and rich ordeals in top quality administration. Until now, above 100 nationwide technologies patents of tower crane have been set into use previously.

3.In order to guarantee the reliability of tower crane high quality and lessen the expense, all raw supplies are immediately supplied by famous manufacturers like Baosteel and Wisco. Raw components for major elements these kinds of as standard part principal limbs, tower caps adopt Q345B metal, thus the tensile toughness improved by 30% and the tower crane turns into more safe and reliable. 

4.Dahan tower crane is the enterprise which to begin with commenced to use the robot welding traces. At existing, we have a fully automated robotic welding creation line for mast sections fabrication produced up by far more than one hundred welding robots. The manufacturing line is composed with computerized material preparing, welding and maching. All principal components of Dahan tower crane use robot welding, with the most ept carbon dioxide mixed with argon gas shielded welding, it has deep depth of fusion, substantial top quality of welding and steady performance.


five. All areas and parts of EPT tower crane use high quality manufacturers. Electric tools with Schneider converter, aviation plug, stainless metal distribution box and three linkage console has features of low failure charge and straightforward installation.
Hoisting system is supplied by major manufacturer Jiangte Motor or HangZhou Shengjian, all with motor oil, free of charge routine maintenance, large reliability and reduced maintenance fee.
Slewing support utilizes HangZhou Fangyuan brand or Rothe Erde brand, two times tempering processing helps make much more efficiently operation and lengthier tower crane services lifestyle.


6. Focus to element quality.  High-strength bolt undertake shipborne scale DACROMET technology. It can preserve not rusted for 10 years .Swiss screw-thread bolts of preload advertise 30 per cent than standard bolts. Weight limiter utilizes the rigidity ring composition and forged aluminum shell used Hoisting, derric ept restricting stopper to increase services daily life.

seven.Big constructions as mast area, switch ready, prime kit and hoisting jib undertake superior tools as NC device device, drilling machine, milling machine processing soon after welding. That efficiently assures merchandise assembly precision, lowering the failure fee and improving the protection.


eight.12 automated spraying assembly line, the complete equipment adopt impeller blasting to ensure the cleanliness of metal area and eliminate the internal pressure creating in welding process, boost the toughness and metal surface hardness, increase portray adhesion. Two primer, a paint spraying engineering, lovely physical appearance, corrosion resistance has elevated much more than twice than the daily life of normal spraying approach. System, the little auto, fence and other small pieces undertake scorching dip galvanized following acid phosphate remedy, rust resistance much better.


nine.Hoisting, derric ept and slewing system, with total basic safety this kind of as torque, excess weight restrict. The steel wire rope broken rope unit. Range of the auto design and style against decline and damaged shaft, this sort of as tilting unit. The electrical adopts overload protection, the style of PLC self-prognosis technique, it is handy to maintenance.

ten.Dahan three creation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to a lot more than fifty nations and areas. We have much more than a thousand sets after-income support community. We carried out the earliest stagnation stage services manner in this tower crane ept that guarantee the quality of service and efficiency. Otherwise, better to eliminate customer’s worries.
