QNP31.5(TC4207/3808) Inner Climbing Tower Crane-3T
QTZ31.5 type selferecting towering crane is novel hosting vehicle meeting the needs of assembling
medium or high construction equipment. The product is an upper rotary selferecting kind with horizontal
ledge, trolley amplitude. Jib length is 42m, maximum rated weight is 3t, and rated maximum lifting moment
is 200kN.m. The following is the main characteristics.
1. Wide applicability. The tower crane not only meets the usual civil construction demand of small and
mediumsize cities, but the highrise and multilayered civil construction demand of large and mediumsize
cities. It can also be used in the construction of multilayered industrial factories, in the slipform construction
of huge chimneys and silos and in goods loading in port or goods yard.
2. Easy to assemble and disassemble. Hydraulic hoisting device is adopted to increase or reduce crane
standard section, which corresponds to changing height of various constructions.
3. High speed, easy adjustment, stable operation and high efficiency. Low speed with heavy load and
high speed with light loads can be realized through hoisting structures. Two kinds of speed of trolley can
meet operational needs. Open stopper is equipped to rotating structure, enabling precise placement and
easy assembly of crane.
4. Complete and reliable safety protective devices. The product is equipped with weight limiter, moment
limiter, height limiter, amplitude limiter and rotary limiter to ensure normal operation. In addition, rest platform,
guard ring are also equipped.
5. Driver’s cabin is separately set on one side. It is broad, bright, comfortable, safe and easy to operate.
The basic height (detached) of supplied tower crane is 25.5m. If it is used in high-rise construction, the number of standard sections and attached devices can be increased to meet
consumers’ needs. The maximum height of the product is 120m.
