This wide base umbrella anchor bolt is designed for heavy loads in industrial environments where large equipment such as presses, turbines, and compressors must be securely anchored to concrete foundations. The distinctive umbrella-shaped base creates a broad bearing surface that effectively distributes forces over a larger area, minimizing stress concentrations that could lead to concrete failure. Available in diameters from M20 to M30 and lengths from 800mm to 2000mm, this bolt is engineered for demanding heavy machinery installations. The umbrella head is formed through specialized hot forging, creating the characteristic curved profile that provides excellent load-spreading performance while maintaining structural strength. Manufactured from Q345B high-strength structural steel with hot-dipped galvanized finish, this anchor delivers exceptional durability and corrosion resistance in challenging industrial conditions. While L-type anchor bolt is commonly used for standard building foundations, this umbrella anchor is specifically designed for heavy equipment bases where load distribution is critical.
The manufacturing process involves precision hot forging to create the umbrella-shaped head, followed by thread rolling on the shaft. The head dimensions and profile are carefully controlled to ensure consistent performance. Quality control includes dimensional verification, head profile inspection, coating thickness measurement, and load testing. This bolt is commonly specified for large presses, heavy turbines, industrial compressors, and other impact-generating equipment. The umbrella design effectively spreads loads over a wide area, preventing localized concrete damage and reducing vibration transmission. In projects where 9-shaped anchor bolt is used for different load conditions, this umbrella anchor provides superior load distribution for heavy rotating equipment.
Installation requires careful positioning of the umbrella head within the concrete formwork to ensure full embedment at the correct depth. The head must be oriented correctly to achieve its full load-spreading capability. Positioning templates are provided to ensure accurate placement, and the bolt is secured before concrete pouring. Once the concrete has cured, the exposed threaded rod provides a reliable connection point for equipment mounting. Umbrella-type anchor bolt shares this load-spreading principle, making it a preferred choice for heavy industrial installations. Plate-type anchor bolt offers a different approach with a flat plate design, while this umbrella anchor features a curved profile optimized for heavy equipment bases. Light pole anchor cage applications typically use different anchoring methods, while this umbrella head bolt is specifically designed for heavy equipment foundations where load distribution is critical. Custom head sizes and rod lengths can be produced to meet specific project requirements, ensuring the anchor matches the equipment base plate dimensions precisely.
