Highlights:

1. The upper chord of the boom is connected by high-strength pins of "three-plate clamp and two-plate", and the lower chord adopts a box-type single guide rail structure, which is connected and positioned by a positioning pin, 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 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.

4. The electromechanical hydraulic automatic assembly and disassembly system adopts hydraulic pin puller to reduce the labor intensity of installing small-diameter pin shafts and improve the installation speed of tower cranes.

5. Adopt luffing rope tightening technology, humanized design, no need for climbing operation, reduce the weight of the luffing trolley, improve the lifting performance of the tower crane, and the operation is flexible and convenient.
