1. Improve work efficiency: Tower cranes have the characteristics of large lifting capacity, strong wind resistance, strong reliability, and flexible operation. These features increase construction speed and reduce labor costs.
2. Enhance security: Construction tower cranes can operate at high altitudes on site without endangering workers' safety, and can improve transportation efficiency and reduce workers' handling risks.
3. Small scale and wide scope of cooperation: The use of construction tower cranes can adapt to various construction site environments without taking up a lot of space. It can be used in busy cities or more remote areas, bringing more benefits to the construction industry. possible.
4. Easy maintenance: Tower cranes require little maintenance during operation, requiring only regular inspection and replacement of minimal rotating parts, making the project safe and long-lasting.
5. Enhanced aesthetics: The platforms and railings undergo galvani zation treatment, while pivot pins and bolts are coated with colored zinc or galvanized using DACROMET technology, ensuring both visul appeal and strong corrosion resistance.
6. Convenient packaging: The overall design of the crane follows container dimensions, facilitating transportation for export purposes.
