QTK20 self erecting tower Crane

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

QTK20 fast erected Crane is an entirely delivered and quickly erected machine for vertical and horizontal transportation.
QTK20 fast erected Crane s suitable for civilian constructions from 7 to 10 storeys(10-11storeys when jib upwards, less than 8 storeys when jib is level). Besides, QTK20 fast erected Cranecan 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 fast erected Crane s easy to be quickly erected and be

completely delivered. When the QTK20 fast erected 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 fast erected Crane is erected by a winch and a whole set of wire

rope pulley system.

3.5 QTK20 fast erected Crane an change from rail travelling to fixed supports

and vice versa according to requirements.

3.6 The jib of QTK20 fast erected Crane 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 of QTK20 fast erected Crane has a variable-pole-speed motor.It can

shift working speed with load.

3.8 The slewing system of QTK20 fast erected Crane has a hydraulic clutch and brake

to ensure smooth start.

3.9 The safety devices of QTK20 fast erected Crane are complete,sensitive and reliable.
