QTK20 quick assembling Crane is a new type of tower crane developed by Institute of Building Mechanization China Academy of Building Research.

QTK20 quick assembling Crane is an entirely delivered and quickly erected machine for vertical and horizontal transportation. QTK20 quick assembling Crane is suitable for civilian constructions from 7 to 10 storeys(10-11storeys when jib upwards, less than 8 storeys when jib is level). Besides, QTK20 can also be used for transportation and stack of goods in workshops, freight yards,rail stations,docks etc. It is also a kind of mobile hoisting and conveying machine

The main feature of QTK20 quick assembling Crane is easy to be quickly erected and be 

completely delivered. When the QTK20 quick assembling Crane is folded, it can be delivered 

to the construction site by a truck,then it can be self assembled(including outer tower mast's 

erecting, inner tower mast's stretching from outer mast, jib's unfolding and counter weight

 installation) within a certain time by its own mechanism with the assistance of one mobile 

crane and two workers. 

3.1 The inner tower mast can lock or unlock automatically when it has stretched 

or retracted in accurate position.

3.2 Jib can unfold or fold in th air automatically in the process of tower masts' stretching 

or retracting.

3.3 Tower mast stretching,jib unfolding and counter weight installation can be finished 

within the whole range from 0° to 360°.It is the same to crane dismounting.

3.4 QTK20 quick assembling Crane is erected by a winch and a whole set of wire 

rope pulley system. 

3.5 QTK20 quick assembling Crane can change from rail travelling to fixed supports 

and vice versa according to requirements.

3.6 The jib can go 30° upwards to increase the hoisting height with a maximum lifting capacity of 800kg,when the trolley can not move .

3.7 The hoisting system has a variable-pole-speed motor.It can shift working speed with load.

3.8 The slewing system has a hydraulic clutch and brake to ensure smooth start.

3.9 The safety devices are complete,sensitive and reliable.
