QTZ125(6515) tower cranes are produced adopting international up-to-date technique for design of tower crane by our company. The whole machine has the following characters: Beautiful shape, novel structure, low consumption, high performance, big work space, high work efficiency. It is applicable to middle and high structure.
 
Tower crane description: 
1.The using steel is 16M and Q235B which the manufacture is Shanghai Bao steel. 
    After test for qualified, then can use.

2.Painting Process. After shot-blast cleaning, spraying anti-rust paint, then spray paint.

3.Welding process use high-strength wire. 
   Main joints use special steel and special process. 

4.Electric device.
  Use international well- known manufacturers' electrical products, such as Schneider. 

5.Motor, deceleration devices use domestic famous manufacturers' products, 
   eg:  Shanghai, Jiangxi Special Electric Motor Co., Ltd.,Tianjin etc, to ensure the long life.

6.For cab, electrical device box, acid cleaning and parkerising, 
   then painting, to ensure a long usage life.

7.Machine total weight is 3-5 tons heavier 
   than the same type of tower crane in other manufacturers.

8.Each device is in strict test,  then can packed to ship, 
   to ensure that the trouble after leave the factory reduced to the minimum.

9.Reliable quality, advanced technology, reasonable price, the best configuration, 
   high safety factor, cost-effective
