QTZ31.5 Tower Crane

Tower cranes are used to lift a variety of building materials and have been widely used in the construction of high-rise buildings, including hotels, residential, industrial buildings and tower buildings.

The tower crane of our company has novel design, reasonable structure and reliable operation. The construction equipment has a variety of practical devices such as horizontal arm bracket, arm trolley reducing mechanism, hydraulic self-propulsion mechanism and various safety devices, and has good speed control performance, working efficiency and running stability.

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.
