Item Description


Transient Introduction:
This sort tower crane has a horizontal jib frame, a jib-trolley radius-modifying mechanism and a hydraulic self-boosting mechanism.  It is original in style, trustworthy in operation and satisfactory in condition.  Equipped with all needed security devices, these cranes present a good pace-control potential, satisfactory functioning balance and higher perform effectiveness.  

The QTZ collection tower crane is largely employed for housing construction in the vertical and horizontal transportation of supplies and the set up of building conponents.

It is broadly employed in infrastructure development ,large-pace rail,oil fields,big ports,nuclear CZPT ,wind CZPT and other development fields.

In accordance to the form of the tower crane ,it can be divided into topkit sort,topless sort and luffing growth kind.

According to the doing work efficiency ,it can be divided into common kind and frequency conversion kind.

1.Suitable for all sorts of design project and can operate beneath all kinds of work problem.
 2.It has higher operating speed, great speed-modifying functionality, continual procedure and high  efficiency.
 3.The crane has total set of protection units, which can assure the protected and large efficient  operation of the products.
 4.Three-pace motor and mono-velocity ratio decelerator are applied in the lifting framework, which  enables heavy load low velocity and light load large speed.
 5.World gear decelerator is applied in the circumcise ranking composition, collectively with minute-limiting  hydraulic pair, which can realize substantial load potential, continual beginning and reliable procedure. 

Safety  Decices:

Bodyweight limiter
If the substance is in excess of the potential, the crane will give a sharp warning for   protection itself
Moment limiter
True-time monitoring and detection of crane doing work circumstances, with its own diagnostic purpose, fast harmful standing alarm and security handle.
Height limiter
Handle the least expensive and optimum severe position of lifting hook
Slewing restrict
Management the severe turns amount of switch remaining and appropriate.


Crisis brake
 If the operation staff  encounter some unexpected emergency situation, we could start off the emergency brake technique to defense the connected treasure.

Handle System:
Hoisting system is pushed by three-speed electromotor with higher operating velocity and very good pace-modifying ability and substantial efficiency Derrick mechanism using worm-wheel reducer can meet operating needs. Slewing mechanism that is pushed by two-velocity electromotor Make operation a lot more secure and reliable.
