Tower Crane Qtz4208 Max Capacity 4t with 42m Jib
We started manufacturing tower cranes from the very year our firm founded in 2001. And now can offer tower cranes with a maximum lifting load form 2.5t to 16t, which is from QTG25, QTZ25, QTZ31.5, QTZ40, QTZ63, QTZ80, QTZ100, QTZ125, QTZ160 and QTZ260, to meet the demand of various kinds of customers in different construction works.
With climbing cage, our crane can change the height itself by adding and reducing its standard sections.
And the same tower crane can have different lengths of jib with different quantities of jib sections. We will offer the drawing of the same when the goods are delivered.
The pedestal can be fixed type of crossing beams and can also be with counterweight to save the space.
Our tower crane with drivers cabin with electric fans or air conditioners according to customers requirements.
For the safety, we can also offer indicator to show the load and height data of crane in service.

Description of QTZ series tower Crane
1) the tower crane is one of the most popular type and hot-selling self-erecting tower crane, which is researched and designed by Institute of Building Mechanization of China Academy of Building Research. It absorbs many advanced technology both from China mainland and abroad.
2) We adopt to use Dual drawbars structure on lifting boom, which enables the lifting boom to be unfer no stress at lifting surface other than uniaxial stress, and moreover, it gets rid of the stress peak. It greatly improves the fatigue safety performance of lifting boom.
3) Adopts VVVF stepless speed variation device for lifting, radius changing and slewing mechanisms, to make sure it works steadily and effectively, it also lowers the maintenance cost.
4)We can offer crane standard sections such as the FO/23B standard sections for customers to choose from.
1.) Providing timely delivery, standby engineers are ready to solve any problems
2.) Providing 12 (twelve only)months product warranty period,with ample spare parts
3.) Providing work site installation guidance and training of operation and maintenances
