Advantages of DAHAN
Shandong Dahan Construction Machinery Co., Ltd was founded in Dec. 2000, specialized in manufacturing various types of tower cranes and construction elevators, and is pioneer of Chinese tower crane industry. At present our products cover 9 series and more than 20 models, such as QTZ40, QTZ50, QTZ63, QTZ80, QTZ125, QTZ160, SC200/200, the technical indicators have reached the leading level at home and abroad.
1. All of our raw materials were purchased from big steel factory
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.
QTZ40, QTZ50, QTZ63, QTZ80, QTZ125, QTZ160, SC200/200, the technical indicators have reached the leading level at home and abroad.
2. DAHAN is the first company to adopt robot system for mast sections and main chord in China
Dahan company is 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 of main load structure has reach has reach advanced international degree in the same industry.
The turntable adopts robot automatic welding, make perfection more perfect and guarantee the quality of every product; mast section of construction elevator adopt tooling positioning and robot welding. It is not only guarantee the interchangeability of mast section and precision of rack positioning but as well make the welding more reliable and durable.
3. Automatic impeller blasting and spraying assembly line
Dahan company adopt the world first-class automatic spraying assembly line. The 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.
4. Strict quality examination for raw materials and the whole crames
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.
5. Completed safely protection devices
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.
