QTK20 quick assembling Crane
QTK20 self erected Crane is a new type of tower crane developed by Institute of Building
Mechanization China Academy of Building Research.
QTK20 is an entirely delivered and quickly erected machine for vertical and horizontal transportation.
It 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 is easy to be quickly erected and be completely delivered. When the QTK20 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 is erected by a winch and a whole set of wire rope pulley system.
3.5 QTK20 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.
