Highlights:

1. The upper chord of the boom is connected by high-strength pin shafts of "three plates and two plates", and the lower chord is in the form of a box-type single guide rail structure, which is connected and positioned by positioning pins, which is convenient for installation and disassembly.

2. The self-suspension and self-decoupling electric introduction system is adopted, and the standard section can be directly hoisted from the ground to the introduction beam. The tassel can pick up and hang the standard section by itself, without the assistance of the press and dismantling personnel, saving manpower.

3. The automatic balance synchronous jacking system, the cylinders on both sides are synchronized smoothly, breaking through the technical bottleneck of double-cylinder or even multi-cylinder jacking of large-tonnage tower cranes, which is the first case in China.

4. The automatic deviation correction function of the luffing trolley makes the safety system of the luffing trolley more perfect, which greatly improves the life of the boom track and the safety performance of the tower crane.

5. Double brake lifting mechanism of tower crane, adding hydraulic brake caliper as the second brake, increasing the reliability of equipment operation, reliable and sensitive braking action, and improving the safety performance of tower crane.
