three.In order to promise the reliability of tower crane top quality and minimize the expense, all uncooked resources are straight provided by popular brands like Baosteel and Wisco. Uncooked resources for principal parts this kind of as regular area principal limbs, tower caps undertake Q345B steel, hence the tensile strength improved by 30% and the tower crane turns into more risk-free and reliable. 


four.Dahan tower crane is the company which to start with began to use the robotic welding lines. At current, we have a fully automated robotic welding prshock guardIndustries that commonly use Torque Limiters to safeguard their equipment incorporate: General machining and manufacturing Packaging and assembly solutions Printing and converting industries Textile production Forest products Distinct programs for Torque Limiters include: Conveyors: If the conveying technique jams, the Torque Limiter will disconnect the driving motor from the conveyor to protect critical parts. Gearboxes: This additional protection mechanism prevents excess torque from achieving vulnerable elements in the pushed technique. Turbines: Power outages can lead to sporadic times of excessive torque. A Torque Limiter can stop that force from detrimental the equipment. Motors: The Torque Limiter can disengage the motor shaft from the pushed program in the event it generates as well considerably torque for the machinery to handle.oduction line for mast sections fabrication made up by more than one hundred welding robots. The creation line is composed with automated materials planning, welding and maching. All principal areas of Dahan tower crane use robotic welding, with the most ept carbon dioxide combined with argon gas shielded welding, it has deep depth of fusion, substantial high quality of welding and stable performance.


5. All components and elements of EPT tower crane use high quality brands. Electric powered tools with Schneider converter, aviation plug, stainless steel distribution box and a few linkage console has characteristics of low failure price and easy installation.
Hoisting system is offered by leading producer Jiangte Motor or HangZhou Shengjian, all with motor oil, cost-free maintenance, substantial trustworthiness and lower routine maintenance rate.
Slewing help utilizes HangZhou Fangyuan brand name or Rothe Erde model, twice tempering processing tends to make far more easily procedure and longer tower crane provider existence.


six. Focus to element quality.  High-toughness bolt adopt shipborne scale DACROMET technology. It can keep not rusted for ten years .Swiss screw-thread bolts of preload encourage thirty p.c than traditional bolts. Fat limiter employs the pressure ring structure and cast aluminum shell employed Hoisting, derric ept restricting stopper to extend provider daily life.



seven.Big buildings as mast area, switch capable, prime package and hoisting jib adopt innovative tools as NC equipment instrument, drilling equipment, milling device processing after welding. That properly assures items assembly precision, minimizing the failure charge and strengthening the safety.


eight.twelve automatic spraying assembly line, the whole machine undertake impeller blasting to make sure the cleanliness of steel surface area and eradicate the inside stress making in welding procedure, improve the energy and steel floor hardness, enhance portray adhesion. Two primer, a paint spraying technologies, gorgeous appearance, corrosion resistance has enhanced far more than 2 times than the daily life of normal spraying process. Platform, the little vehicle, fence and other small pieces undertake scorching dip galvanized right after acid phosphate therapy, rust resistance much better.


nine.Hoisting, derric ept and slewing mechanism, with complete safety this kind of as torque, fat limit. The metal wire rope damaged rope gadget. Assortment of the vehicle design in opposition to reduction and damaged shaft, these kinds of as tilting system. The electrical adopts overload security, the design of PLC self-analysis system, it is hassle-free to routine 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 far more than a thousand sets right after-sales services community. We carried out the earliest stagnation level support manner in this tower crane ept that make sure the high quality of support and effectiveness. Otherwise, better to get rid of customer’s problems.
