PC project construction is a new construction mode which conforms to the development trend of building industrialization. It has the advantages of unique construction mode, short construction period and wide adaptability. PC project construction implements the production mode of combining production industrialization with construction, installation and assembly. Higher requirements are put forward for lifting weight and accuracy of lifting equipment.

Sichuan Construction Machinery (Group) Co., Ltd., which has many years of tower crane production history, is mainly composed of medium-sized and large-scale models, with several combinations of tower body sections of 2 meters, 2.5 meters and 4 meters. The independent height of tower crane is relatively high. At the same time, the mechanical transmission is stable, the hoisting position is accurate, and it can adapt to PC project construction very high.

This time, SCM's C7030 tower crane was used. The maximum lifting weight of C7030 tower crane is 16t, the maximum operating range is 70m, the section of tower body is 2m, and the main chord is angle steel. The mechanism configuration adopts stepless speed regulation, starting and braking balance, which increases the safety and reliability of lifting operation. The performance of the tower crane fully meets all kinds of strict requirements of PC project, such as load, accurate hoisting and so on. At the construction site, six C7030 tower cranes have improved the efficiency of construction operation through reasonable and effective layout, and laid a solid foundation for completing the project construction on schedule.
