High Quality How to get it?
Raw material is the foundation of product and the first hurdle to guarantee quality. Dahan tower crane bulk purchase steel directly from big steel factories like Baosteel and Wisco, improve the safety of product.
First Class Components
First-class product composed by first-class components, DAHAN always insisted to use the first class components, as Fangyuan support, Schneider electric element etc.
Advanced processing equipment
We have the most advanced processing equipment, such as the large laser cutting machine,CNC plasma cutters, CNC drilling machines, lathes, milling machines, sawing machines and others.
Robot automatic welding system and post-weld overall processing equipment
We are the first company to adopt mast sections and main chord robot welding system in the same industry in China. This system is reliable in the performance, with high work efficiency and high automatic degree. The welding quality more reliable and durable.
Main limbs of the mast section, the turntable and other components are all processed and drilled after welding to improve the accuracy.
Automatic impeller blasting and spraying assembly line
Large structure parts are dealt with impeller blasting before spraying. That remove steel surface oxides and welding spatters effectively, eliminates the internal stress producing in welding process, increases the parts' anti-figure strength and steel surface hardness, increases painting adhesion and prolong the service life of the product maximizes efficiency and saves energy
Strict quality examination
Dahan have the strict quality test, raw material test, test of welding, checking welding quality of appearance, assembly and adjustment of jib, tower head and pivot in factory.
Completely safety protection devices improves the safety, weight limiters, adopt the advanced pull-ring structure from abroad, moment adopt bow-board mechanical type which can be used in severe wild environment.
We have professional packing person to put the tower crane in the container or on to the truck.
