Features and advantages:
1. This machine has a wide range of adaptability, which can not only meet the needs of general civil buildings in small, medium-sized, and urban areas, but also fully meet the needs of high and multi-story civil building construction in large and medium-sized cities. It can also be used for the construction of multi-layer and large-span industrial factories, as well as tower-shaped buildings such as tall chimneys and silos that use sliding membrane construction. It can also be used for loading and unloading work at ports and freight yards.
2. Easy installation and disassembly, using hydraulic lifting devices 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, making it spacious, comfortable, safe, easy to operate, and with a good view
