I. main features of mobile boom crane:

1. Can work in a small working area, suitable for group tower operation.

2, good combination of arm, easy to achieve different working range.

3. Mechanical safety device and electronic safety monitoring device are installed to realize mechanical and electronic double protection and monitor the current working status of tower crane.

4. The lifting and amplitude changing mechanism adopts frequency conversion control, which is stable and reliable.

5, the luffing mechanism with a second brake (safety disc brake) to improve the safety of the tower machine operation.

Ii. Core technologies and innovations:

1, the use of high strength structural steel, * limit to reduce the weight of the boom, reduce the power of the luffing mechanism, greatly improve the payload;

2. Adopt modular design, the interchangeability of tower crane arm joint is strong;

3, configure a display, with load, torque measurement, boom Angle, lifting height and other sensors, can display the lifting weight, torque, lifting height, lifting weight range, wind speed and other data, through the PLC at any time to measure the value and the allowable value, security protection, display intuitive and safe;

4. The balance arm focuses on optimizing the design, reducing the turning radius of the tail, increasing the installation requirements of the tower crane on the building, and expanding the application range of the tower crane.
