QTZ40(4808)construction tower crane
All of construction tower cranes are incorporated with
internationally advanced "Tower Crane Computerized Design
Platform(TCDP)" optimized design,featuring in advanced mechanism,
uniform load bearing,good appearance,superior performance and
complete,reliable safety devices.
QTZ series tower crane is a kind of upper-slewing fixed type tower
crane. It can be used into every kind of industrial and civil
construction, especially suitable for the construction site which
is narrow and landform is complicated.
Tower crane has hoisting, slewing and trolleying mechanisms. They
can work respectively or together to raise working efficiency.
Hoisting mechanism adopts double-speed electromotor, it 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. It can satisfy vertical and level
transport demand of construction at a time.
