What is a Tower Crane Fixing Angle?
A tower crane footing, also commonly known as an "embedded section" or "foundation section," is a crucial structure connecting the tower crane tower body to the concrete foundation. It acts like the "roots" of the tower crane, safely transferring all the forces borne by the crane to the ground.
What are the main types and characteristics of Fixing Angle?
1. Embedded Section Type: Reasonable stress distribution, reliable connection, and convenient installation; currently the most mainstream type.
2. Anchor Bolt Type
Advantages: Suitable for certain tower crane models or foundation types.
Disadvantages: Requires extremely high positioning accuracy for the bolts; pull-out resistance is slightly weaker than the embedded section type.
What are the core components of the Fixing Angle system?
1. Embedded Section/Foundation Frame
2. Anchor Bolts (if bolt type)
3. Fixing Frame: A rigid frame welded from structural steel (such as channel steel, angle steel).
4. Concrete Foundation: The platform supporting the entire anchor system and tower crane, typically a large-volume reinforced concrete structure, providing the necessary compressive, tensile, and overturning resistance.
What are the key processes in construction and installation?
1. Design and surveying
2. Excavation and foundation pouring
3. Reinforcement binding
4. Anchor positioning and fixing (the most critical step)
5. Concrete pouring and curing
6. Tower crane installation
Why are tower crane Fixing Angle important?
Even slight deviations in the center, elevation, and levelness of the fixing angle can be amplified into huge errors at a height of tens of meters, causing the tower to tilt, increasing additional bending moments, and potentially leading to serious safety accidents. Although buried deep underground and invisible, it is the cornerstone of the safe operation of the entire tower crane.
