1. Brief Introduction
QTZ160 Tower Crane is a new type of large tower crane for
construction developed through adopting technology by Shandong
Huaxia Group in 2000. During designing, general operations like
limited meta count of steel structure parts, parameter optimization
of entire crane, stability check of entire crane and choice of each
mechanism, etc. are completed with computerized tower crane design
platform, which has reached international leading level.
Max. hoisting moment of QTZ160 (6516) Tower Crane is 1940kn/m, and
each index of performance occupies leading position among domestic
products of the same grade. Its advantages are as follows:
- Hoisting arm can reach 65m, which largely increases covering area,
and its working scope can satisfy constructions of more than two
- It has many working modes with largest application range.
Groundwork is poured on the ground without under frame, and tower
crane is fixed directly on the groundwork. This method makes tower
crane spare groundwork section and crossing girder, and separate
working height of tower crane is 46.2m under such condition.
If construction object is high, tower crane can adopt attaching
mode, and hoisting height can reach 161-200m. If it is required to
be higher under special conditions, please contact our company.
No matter which kind of mode is adopted, hoisting arm has lengths
of 55m, 60m and 65m, which can be chosen according to different
- It adopts hydraulic hoisting system to increase or reduce standard
sections, which makes height of tower crane rise or fall according
to height of construction to adapt construction of different
- Working speed is high, timing performance is good, and working
efficiency is high.
Hoisting mechanism adopts double speed double pulley winding motor
to realize low speed on heavy load and high speed on light load,
and max. speed can reach 100m/minute. Start and brake are steady,
impact is small, and operation is convenient. Swing mechanism
adopts domestically advanced frequency conversion timing project,
which makes start and brake become steady and reliable.
- Horizontal Arm Frame and Trolley Radius
The tower crane adopts horizontal arm frame, load is hung in
hoisting trolley, and radius is realized through horizontal
movement of trolley on arm frame. Compared with luffing jib tower
crane, working is steady, installation is convenient, and radius
application is wide, which can make hoisting performance be fully
exerted, enlarge storing range of construction materials, and make
disposal of general construction ichnography be convenient.
- Safety devices are complete, and there are brakes fixed in each
mechanism, which can ensure working safety. There are safety
protecting devices like hoisting height restrictor, trolley radius
restrictor, moment restrictor, hoisting weight restrictor and swing
restrictor, etc. fixed in tower crane.
- Driving room is set separately on side with good field of vision
and large working space, which create better working environment
- Operation is convenient, and maintaining is simple.
Electric control system adopts domestically advanced PLC control
with automatic malfunction judgment, overload and over moment
safety chain protection, motor overtime protection, program
controller of famous Japan Mitsubishi Company, transducer of Japan
Yaskawa Company, relay of OMR Company and contactors manufactured
through introducing technology of TE Company, which makes its
reliability be much higher than general electric control systems.
It is safe and reliable with less malfunctions.
There is no central collector to avoid disadvantages of short
circuit and creepage because of damp and make entrance and exit of
driver be easy.
More than 2,800 employees and a countrywide production, sale and
after service network ensures strategic advantage on production and
design of products of Shandong Huaxia Group.
Products of Shandong Huaixa Group are the best choice for selecting
