Advantages Of Tower Crane:

1. It has a wide range of adaptability and meets the needs of high-rise and multi-story civil building construction in small, large, and medium-sized cities. It can be used for the construction of multi-story and large-span industrial factories, as well as tower-shaped buildings such as tall chimneys and silos that use sliding formwork construction. It can also be used for loading and unloading operations in ports and freight yards.

2. Easy to install and disassemble, hydraulic lifting device is used to increase or reduce the standard section of the tower body, so that the lifting height of the tower crane can adapt to changes in building height.

3. High working speed, good speed regulation performance, stable operation, and high efficiency. The lifting mechanism basically achieves heavy load, low speed, and light load, high speed.

4. The safety protection devices are complete, sensitive and reliable.

5. The driver's cab is independent and external, and uses a linkage console to control various mechanisms, which is spacious, comfortable, safe, easy to operate, and has a good view.
