Q1: What is the function of an Anchorage Frame?
A: When a tower crane needs to reach heights beyond its free-standing limit, it must be attached to the building structure. The Anchorage Frame (also known as a tie-in collar or wall tie frame) encircles the tower crane mast section and connects it securely to the building using tie bars. This allows the crane to gain extra operational height safely.
Q2: Why is the Anchorage Frame so important?
A: Safety and structural stability are critical in high-rise construction. The anchorage frame distributes forces—such as extreme wind loads, rotational torque, and lifting weight—from the crane to the building structure. It prevents the crane mast from swaying or buckling, ensuring safe operation at extreme heights.
Q3: Which Liebherr models and mast sizes are compatible?
A: Our anchorage frames are custom-engineered for various Liebherr tower crane models and mast specifications:
1. Compatible Models: Liebherr 120HC, 132HC, 154HC, 256HC, and 290HC.
2. 1.6M Mast Fit: Designed for 180mm × 18mm angle steel.
3. 2.0M Mast Fit: Designed for 200mm × 20mm angle steel.
Q4: What makes our Anchorage Frames stand out?
A: We prioritize manufacturing quality, structural safety, and durability:
1. Superior Surface Treatment: Standard sections undergo an overall sand-blasting and anti-corrosion treatment. We use top-tier industrial paints for high adhesion and maximum weather resistance.
2. Precision Welding: All chord connections feature gas-shielded welding for strong, reliable joints.
3. Rigorous Quality Testing: Every unit undergoes weld inspection, X-ray testing, and UT ultrasonic testing to guarantee zero defects before delivery.
Q5: Frequently Asked Questions (FAQ)
Q: When should an anchorage frame be installed?
A: It must be installed as soon as the tower crane exceeds its designated free-standing height, or as required by the site engineering plan.
Q: Do you offer custom tie bar designs?
A: Yes! We provide custom tie bar and anchorage solutions tailored to your specific job site dimensions and building conditions.
Q: What certifications do your components hold?
A: Our production meets strict international standards, backed by CE, ISO9001, and TUV certifications.
