1. The performance parameters and technical indicators are domestically leading, with a maximum working range of 32m and an inner-climbing maximum lifting height of 120m.

2. The appearance of the whole machine is of international popular style, very beautiful, and deeply loved by users at home and abroad.

3. Multiple working methods and wide application range. The internal climbing working method is suitable for various construction objects.

4. High working speed and good speed regulation performance. The radius changing mechanism adopts the most advanced frequency conversion stepless speed regulation scheme in the world, making the work more stable and reliable.

5. The main electrical components of the electrical control system are from international famous brands. Their service life is 3 to 4 times longer than that of domestic components. They have fewer faults, simple maintenance and reliable operation.

6. Various safety devices are available and are mechanical or mechatronic products, which are suitable for harsh construction environments and can ensure reliable operation of the tower crane.

7. While adhering to the principle of being in line with national conditions and ensuring safety and reliability, the design absorbs and adopts mature and reliable advanced technologies at home and abroad as much as possible to improve the technical level of the whole machine. The following mature and reliable advanced technologies are used:

1) Safety devices such as weight limiter, torque limiter, height limiter, amplitude limiter, rotation limiter, rotation and traction mechanism brakes are introduced and made locally.

2) The trolley’s anti-rope breaking device (anti-rolling car) and anti-shaft breaking device;

3) Hoisting mechanism rope arrangement system;

4) Traction rope tensioning system;

5) Rigid double-tie rod suspension large-reaching boom, the boom has good stiffness, light weight, small cross-section, low wind resistance, beautiful appearance, and several length changes to meet different construction needs;

6) The driver's cab is independent and external, with good visibility and large internal space, creating a good working environment for the operator;

7) Advanced linkage platform is used to control the movements of each mechanism, which is easy to operate and maintain.

8. The design fully complies with or is superior to relevant national standards. Because this machine has the above characteristics, it is suitable for large-scale construction projects such as high-rise civil buildings, bridges and water conservancy projects, industrial plants, and tall chimneys and silos constructed using the sliding form method.
