construction tower cranes 

Your personal visit to our factory is warmly welocme,and we hope to do our best host for you then.

construction tower cranes  is a kind of upper-slewing fixed type tower crane.

construction tower cranes can be used into every kind of industrial and civil construction, especially suitable for the construction site which is narrow and landform is complicated.

construction tower cranes has hoisting, slewing and trolleying mechanisms.

construction tower cranes can work respectively or together to raise working efficiency. Hoisting mechanism adopts double-speed electromotor

construction tower cranes has two kinds of work speed: Lifting and slowly in position, so as to satisfy different work requirement. Jib can rotate 360° Freely. Level arm frame, trolley range-changing, agile and reliable, lifting in position is accurate.

tower crane specification can satisfy vertical and level transport demand of construction at a time.Safety devices of this tower crane are reliable

construction tower cranes is equipped with reliable mechanical type moment limiter and lifting weight limiter, it also has lifting height, work range and slewing limiters, so as to ensure the work safety.

construction tower cranes  is designed reasonably, quality is high, structure is compact, and operation is convenient; It is an ideal liftingmachine of construction team.

 Advantages: construction tower cranes 
1. Elements from Simens and Schneider are adopted in electrical system, performance of which is stable and reliable. 
2. Main ports of tower crane is welded with CO2 gas protected welding and full-auto submerged arc welding that makes the stability of the whole machine be improved considerably. 
3. The whole machine runs stably with good adjustable performance. 

Performance introduction: 
The standard section of QTZtower crane is manufactured using on-chip-type or standard section. Rotary uses double-slewing mechanism, hoisting mechanism is dragged by double-speed wound motor, run smoothly. 

4.High working speed and efficiency, great speed-adjustment performance, and stable running; 
5.Wide working range, various working methods, and great applicability; 
6.The whole machine is of reasonable arrangement and beautiful in design; 
7.Complete safety devices, all mechanism are equipped with brake device to ensure the safe and reliable running.
