  qtz63 tower crane

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

  qtz63 tower crane is a kind of upper-slewing fixed type tower crane. 

  qtz63 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.

qtz63 tower crane has hoisting, slewing and trolleying mechanisms.

  qtz63 tower crane can work respectively or together to raise working efficiency. Hoisting mechanism adopts double-speed electromotor,

  qtz63 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.

qtz63 tower crane can satisfy vertical and level transport demand of construction at a time.Safety devices of this tower crane are reliable

  qtz63tower crane is equipped with reliable mechanical type moment limiter and lifting weight limiter,

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

  qtz63 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 QTZ63 6T Tower Crane  

Features of QTZ63 Tower Crane

 

QTZ63 Tower Crane is a new type of construction tower equipment that is researched and designed by Institute of Building Mechanization of China Academy of Building Research based on large formwork construction technology. It has the following characteristics:

 

1) Lifting multiplying factor switchover automatically, without operator's intervention.

 

2) Ahead of all domestic competitors,  we are the first manufacture to adopt lifting rope verticality limit mechanism, which decreases the lifting rope vertical angle under free load lifting mode, and highly improves the tower crane steering performance.

 

3) Our tower sections are exchangeable with the POTAIN H3/36B tower sections, which provide our customers more conveniences.

 

4) We adopt to use Dual drawbars structure on lifting boom, which enables the lifting boom to be under 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.

 

5) 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.

 

6) The equipment adopts to use non-contact computer control system, which provides the high reliability and full functions to avoid drivers' miss-operation.

 Advantages of qtz63 tower crane
1. Elements from Simens and Schneider are adopted in electrical system, performance of which is stable and reliable. 
2. Main parts of tower crane china  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. tower crane china 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. 

4.High working speed and efficiency, great speed-adjustment performance, and stable running; 
5.Wide working range, various working methods, and great applicability; 
6. tower crane china  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.
