Description
QTZ**0 tower crane was designed by China Construction
Scientific Research Institute Construction Mechanization
Sub-Institute and developed by our company. It is a
multiple-function hydraulic auto-lift tower machine characteristic
of upper-circumgyrating, horizontal arm and variable range with
small cabin. The lifting moment is **0KN.m, and the maximum lifting
power is 8t. When independently installed, the maximum lifting
height can reach *5m, and with attachments the lifting height can
reach **0m. The maximum range of it is *6m.
The machine is scientific in design and beautiful in
appearance. The independent driver’s room and its broad visual
field provide a nice work environment for the operator. The crane
is convenient to operate and easy to maintain and repair. It is an
ideal construction machine for construction enterprises. The
machine has four kinds of work structures: lifting, circumgyrating,
variable ranges, and top lifting. The four structures can work in
combination as well as independently so as to improve work
efficiency. The top lifting structure is used to increase the
height of the tower or lower the tower. The lifting control of this
machine has three choices: frequency conversion stepless speed
adjusting, double speed wire winding motor speed adjusting, and
tri-speed motor speed adjusting. The circumgyrating control has two
options: frequency conversion stepless speed adjusting and wire
winding motor speed adjusting. The range adjustment control has two
selections: frequency conversion stepless speed adjusting and
tri-speed motor speed adjusting. The above settings can be made
according to the demands of the customers. All the models work
stably and can fully satisfy different needs. The lifting arm can
rotate **0 to the left and right. The circumgyrating and range
adjusting are agile and reliable, and the hoisting positioning is
accurate. Thus the crane can satisfy the need for vertical and
horizontal transportation in construction operation.
The crane can be widely used in the construction of
higher hotels, residential buildings, higher industrial buildings,
large-span workshops, high chimneys and silos.
The machine can be installed with a *0t truck-style
crane. The installation is convenient and speedy.
