What is a Mast Anchorage Frame for Tower Crane?
A Mast Anchorage Frame (also known as a collar or tie-in frame) is a vital structural component that attaches around the mast section of a tower crane. It connects the crane tower to the building structure using tie bars, ensuring lateral stability and overall safety during high-rise construction.
Why is a Mast Anchorage Frame necessary for high-rise construction?
Beyond its free-standing height, a tower crane requires additional support to gain extra working height safely. The anchorage frame secures the crane mast to the building at calculated intervals, preventing swaying, structural fatigue, or tipping caused by heavy loads and strong wind forces.
Which tower crane brands and models are compatible with these anchorage frames?
Our mast anchorage frames are designed for compatibility with major global brands and models, including:
SYM / SCM / YONGMAO / ZOOMLION models: 1.6M / 2.0M L46A1, L68A1, L68B1, L68B2.
Liebherr models: 120HC, 132HC, 154HC, 256HC, 290HC.
What are the main technical specifications of the 1.6M and 2.0M mast frames?
1.6M Mast Frame: Constructed using 180mm * 18m angle steel.
2.0M Mast Frame: Constructed using 200mm * 20mm angle steel.
How is the surface durability and corrosion resistance ensured?
Each anchorage frame undergoes an overall sand-blasting process to clear impurities, create a smooth surface, and prepare for anti-corrosion treatment. High-grade industry paint is then applied, offering exceptional adhesion, wear resistance, and long-lasting protection against harsh outdoor environments.
What quality control standards are applied to the welding process?
All structural chord connections are gas-shielded welded for superior strength. To guarantee maximum structural integrity, every frame undergoes non-destructive testing (NDT), including visual weld inspections, X-ray testing, and Ultrasonic Testing (UT).
How to select the right anchorage frame for your project?
Selection depends on your crane model, mast section size (e.g., 1.6m vs 2.0m), required working height, and the distance between the crane and the building structure. For exact customization and quotes, contact our technical team with your project requirements.
