3.In order to ensure the trustworthiness of tower crane top quality and minimize the expense, all raw resources are right equipped by popular makes like Baosteel and Wisco. Raw resources for primary parts this sort of as normal section principal limbs, tower caps undertake Q345B steel, therefore the tensile strength enhanced by thirty% and the tower crane gets a lot more risk-free and trustworthy. 


four.Dahan tower crane is the company which to begin with started out to use the robotic welding lines. At present, we have a fully automated robot welding manufacturing line for mast sections fabrication made up by much more than one hundred welding robots. The generation line is composed with computerized materials preparation, welding and maching.

6. Focus to element top quality.  High-power bolt undertake shipborne scale DACROMET technological innovation. It can keep not rusted for ten several years .Swiss screw-thread bolts of preload encourage thirty % than traditional bolts. Excess weight limiter utilizes the rigidity ring framework and cast aluminum shell utilised Hoisting, derric ept restricting stopper to lengthen support existence.



7.Big constructions as mast segment, change capable, top kit and hoisting jib undertake sophisticated products as NC machine tool, drilling device, milling equipment processing soon after welding. That properly ensures goods assembly precision, lowering the failure rate and enhancing the safety.


eight.12 computerized spraying assembly line, the complete machine undertake impeller blasting to ensure the cleanliness of metal floor and remove the interior stress generating in welding approach, improve the power and steel area hardness, boost portray adhesion. Two primer, a paint spraying engineering, stunning look, corrosion resistance has increased much more than 2 times than the daily life of regular spraying approach. Platform, the small vehicle, fence and other little items adopt sizzling dip galvanized right after acid phosphate remedy, rust resistance stronger.


9.Hoisting, derric ept and slewing mechanism, with comprehensive safety this kind of as torque, bodyweight restrict. The metal wire rope damaged rope unit. Assortment of the vehicle design and style in opposition to reduction and broken shaft, this sort of as tilting device. The electrical adopts overload protection, the design and style of PLC self-analysis program, it is convenient to servicing.



ten.Dahan three production bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to much more than fifty nations around the world and locations. We have much more than one thousand sets soon after-sales support network. We carried out the earliest stagnation level service mode in this tower crane ept that guarantee the good quality of provider and performance. Otherwise, better to eliminate customer’s anxieties.



Relevant tower crane product specs

At extremely lower speeds programs can produce a large volume of unneeded torque. This torque can harm push system factors (Shafts, Gearboxes, Chain, Couplings…) in the advent of a jam. A torque limiter will limit the torque to the established degree and prolong technique ingredient life.
