What is a Fixing Angle Anchor Leg?
A fixing angle is a heavy-duty steel component used to securely connect the base mast section of a tower crane to the reinforced concrete foundation. Unlike embedded anchors, reusable fixing angles are designed to be detached and reused on multiple job sites.
Why Are Fixing Angles So Important?
1.Structural Integrity: Transfers the crane’s load—both vertical and horizontal—into the foundation.
2.Safety Assurance: Prevents mast movement, tilting, or uplift under operational and environmental loads.
3.Reusability: Designed for multiple installations, reducing material costs and waste.
4.Precision Alignment: Ensures the mast is perfectly vertical and correctly positioned.
Common Applications
1.New tower crane installations on concrete foundations
2.Relocation of cranes across multiple sites
3.Temporary or long-term construction projects
4.Compatible with various tower crane models and mast sections

❓ Frequently Asked Questions
Q1: What makes a fixing angle “reusable”?
A: Reusable fixing angles are designed with reinforced construction, high-grade coatings, and precision-machined connections that allow them to be safely detached, transported, and reinstalled on new foundations without loss of structural integrity.
Q2: How are fixing angles installed?
A: They are bolted or pinned to the base mast section and securely anchored into the reinforced concrete foundation using high-strength bolts or embedded tie rods. Installation must follow engineered drawings and local safety regulations.
Q3: Can your fixing angles fit different crane models?
A: Yes—we produce fixing angles compatible with a wide range of tower crane mast sections. Custom designs are also available based on technical drawings.
Q4: What inspections are performed before delivery?
A: Each unit undergoes visual inspection, dimensional verification, weld quality checks using X-ray and ultrasonic testing, and surface treatment validation to ensure it meets strict quality standards.
Q5: How do you ensure long-term corrosion resistance?
A: Our fixing angles are sandblasted to remove impurities, treated with high-adhesion primer, and finished with industrial-grade anti-corrosion paint—specifically selected for the demanding tower crane environment.
Q6: What is your typical delivery time?
A: We prioritize short lead times and reliable delivery schedules. Exact timing depends on order quantity and customization requirements—contact us for a detailed quote.
