1. The performance parameters and technical indicators of the machine have reached the domestic leading level. The rated lifting torque is 80t·m, the effective working range is 3~60m, and the maximum rated lifting weight is 6t. The maximum lifting range is up to 60m, independent height 46m, the height of the attached type can reach 150m.

2. The appearance of the whole machine is internationally popular, beautiful and generous, and is deeply loved by users.

3. The machine has fast working speed, good high-speed performance, stable work, and high efficiency. The lifting mechanism basically realizes the low speed of heavy load and high speed of light load; the trolley luffing mechanism has two types to meet the work needs; the slewing mechanism has a normally open A type stopper makes the tower crane in place accurately and is convenient for safe operation.

4. The tower crane has complete safety protection settings, equipped with weight limiter, torque limiter, height limiter, rotation limiter, trolley broken rope protection device, trolley broken shaft protection device and lifting, rotating and luffing mechanism Safety settings such as brakes. All of them are mechanical or mechatronics products, sensitive and reliable, and can adapt to harsh construction environments to ensure the safety and reliability of their work. At the same time, they are also equipped with labor safety protection settings such as resting platforms and guardrails to ensure the installation and disassembly of the tower crane. , Overhaul and personal safety of the driver when going up and down.

5. The driver's cab is independent and external, with good visibility, large internal space, and comfortable and safe operation. Provides a good working environment for operators. The driver's cab operates each mechanism through the cash linkage table, which is easy to operate and simple to maintain.

6. The design of this product fully complies with even the relevant national standards. In the design process of the machine, from the finite element calculation of the steel structure, the optimization of the parameters of the whole machine, the stability of the whole machine to the selection of various mechanisms, the computer system completes the routine design calculations and all the drawing work. The design is scientific and the production is fine.

Based on the above characteristics, this type of tower crane can not only meet the needs of high-rise civil buildings, but also can be used in large-scale construction projects such as bridges, water conservancy projects, large-span factory buildings, and tall chimneys constructed by the slip form method for loading and unloading of ports and freight yards. Homework can also be applied.

This series of tower cranes has horizontal boom, boom trolley reducing mechanism and hydraulic self-lifting mechanism. The design is novel, the operation is reliable, and the appearance is beautiful. These cranes are equipped with all necessary safety devices, have good speed control capabilities, satisfactory operation stability and high work efficiency.

The QTZ80 8-ton tower crane can be widely used in the construction of tower-like buildings such as high-rise hotels, residential buildings, high-rise industrial buildings, large-span factory buildings and tall chimneys.

We have exported to Vietnam, Malaysia, Kazakhstan, Mongolia, Russia and many other countries.
