What is a tower crane anchorage frame?
The tower crane anchoring frame, commonly known as the "attachment frame" or "anchoring frame," is a rigid support component connecting the tower crane tower body to the building structure.
What are its core functions?
1. Enhance tower stability
2. Allow the tower crane to exceed its independent height
3. Reduce bending moment at the tower base
What are its main components?
1. Frame body
2. Attachment rods (support rods)
3. Adjustment device
4. Connecting parts
What are the key points during installation?
1. Timing: Before the tower crane is raised, the anchoring frame should be pre-installed on the tower body and raised to the predetermined attachment height along with the tower crane.
2. Positioning: The attachment point height and horizontal position on the building must be strictly constructed according to the plan. Priority should be given to areas with high rigidity, such as shear walls and frame columns.
3. Pre-tightening: When installing the attachment rods, adjusting devices must be used to evenly pre-tighten each member, eliminating gaps and ensuring a secure connection between the frame, tower body, and building.
4. Verticality Correction: After completing one attachment, the verticality of the tower body must be checked and adjusted to ensure it is within the allowable deviation (usually no greater than 4/1000).
Frequently Asked Questions (FAQ)
What aspects need to be checked and maintained?
Daily inspection: Check the anchoring frame for deformation, cracks, and corrosion; check if the tightening device is loose; check if the attachment rods are straight and if the adjustment device is locked; check if all connecting bolts and pins are intact.
Is regular inspection required?
Of course. Especially after severe weather such as strong winds, heavy rain, or earthquakes, a special inspection must be conducted.
Can it be repaired by myself?
Maintenance requires professional personnel; unauthorized modifications are strictly prohibited. Improper operation can lead to structural damage.
What are the prohibited actions?
1. Strictly Prohibited: Do not arbitrarily disassemble, cut, or weld anchoring components.
2. Do not fix other loads (such as construction elevators or scaffolding) to the anchoring frame; do not walk on the anchoring rod or suspend heavy objects.
The tower crane anchoring frame is the "lifeline" of high-altitude tower crane operations. It is a systematic project involving multiple disciplines such as mechanics, structure, and construction. Negligence at any stage could lead to a major safety accident such as tower crane collapse.
