1. self erect tower crane is a kind of upper-slewing fixed type tower crane. 

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

3. self erect tower crane has hoisting, slewing and trolleying mechanisms.

4. self erect tower crane can work respectively or together to raise working efficiency. Hoisting mechanism adopts double-speed electromotor,

5. self erect tower crane 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.

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

 6. self erect tower crane is equipped with reliable mechanical type moment limiter and lifting weight limiter,

 7. tower crane qtz63-5013 also has lifting height, work range and slewing limiters, so as to ensure the work safety.

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

Main Technical Parameters of self erect tower crane

 Main parts of cranes and lifting equipment  is welded with CO2 gas protected welding and full-auto submerged arc welding that makes the stability of the whole machine be improved considerably. 
 Elements from Simens and Schneider are adopted in electrical system, performance of which is stable and reliable. 

 Advantages of self erect tower crane

3. self erect tower crane runs stably with good adjustable performance. 

Performance introduction: 
The standard section of tower crane china 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.
