QTZ40-4208-4T

tower crane drawing：

Widely used in the construction of various high-rise buildings, the tower crane is configured with a horizontal arm bracket, an arm-trolley radius-changing apparatus, and a hydraulic self-propelling mechanism. Along with all necessary safety devices, this aerial equipment is superior to its counterparts not only in its original design, attractive appearance and secure operation but also in its extraordinary speed-control ability and work efficiency.

Features

1. Hoisting Mechanism：

The tower crane uses a large-size winding drum and the motor with three kinds of speed or with variable frequency system.

2. Slewing Mechanism：

The continuously variable frequency speed regulation helps the balance crane to work with stable starting and braking as well as fast and accurate positioning. Therefore, our tower crane becomes the leading one in terms of performance and operability at home and abroad.

3. Luffing Mechanism：

Adopting variable frequency speed regulation, the luffing mechanism works stably with little impact.

4. Control System：

The PLC allows for automatic detection of electrical fault and issues corresponding sound and light alarm. Critical components are all procured from international famous enterprises.

5. Safety Protection Device：

Our tower crane is equipped with many advanced or ingenious components apart from regular safety devices used in ordinary cranes for the purpose of enhancing its security and operating convenience.

6. Structure：

Tanks to the advanced design tools, such as electro-mechanical design, CAD design, optimization design, and modular design, the tower crane proves to be a kind of optimum construction equipment that shows not only superb strength, stiffness and fatigue resistance but also outstanding comprehensive performance and reliability.
