Product Description

Topless tower crane QTZ50 falls within upper-swing hydraulic climbing tower crane, which is operated by computer from related the steel structure an element to mechanisms and conventional design operations. hoisting mechanism adopts three-speed motor, having three kinds of working speed meets different demands.
 
Advantage:
1. AC contactor, thermprl protector adopt Schneider which is high quality product, stable and reliable in performance
2. The mechanisms adopt the product of professional manufacture, stable and reliable in operation.
3. The first domestic robot welding production line has achieved the main welding quality and reached the international advanced level.
4. Steel structure parts all achieve impeller blasting, improve the surface hardness of steel, and enhance the coating adhesion, extend equipment useful life.
5. Mast sections adopt split structure and storage, save the long distance freight
6. The main chord of mast section adopts Q345B material, fine adaptability to environment
7. The mechanism adopt foreign advanced technical products, reliable in performance
8. High working speed and efficiency, great speed-adjustment performance, and stable running
