Lifting Frame for Handling Large Industrial Equipment Modules

When lifting large industrial equipment modules (50-200 tons each, 5-15 meters in length), a simple lifting frame must strike a balance between "minimal structure, controllable costs, and safety and reliability".

Simplified Design Highlights
Weld-Free On-Site Assembly: The main steel beams and trusses are prefabricated in the factory, requiring only bolted connections on-site (assembly can be completed by two people in four hours), eliminating the need for large lifting equipment.
Adjustable Lifting Point Spacing: The bottom D-shaped lifting rings feature oblong holes (10cm x 2cm) along the web of the main beam. Adjustable lifting ring positions allow for adjustments to accommodate different module lifting lug spacing (adjustable from 1 to 4 meters).
Wind-Resistant and Lightweight: The truss structure is 30% lighter than a box beam and has a 25% lower drag coefficient (suitable for open-air ports and construction sites).

Applicable scenarios: Transferring large machinery modules within factories, loading and unloading heavy equipment at ports, and hoisting prefabricated components on construction sites (such as wind turbine towers and petrochemical reactors). Compared to custom frames, this system sacrifices 5% of its ultimate load capacity, but offers immediate installation and cost savings. It is suitable for hoisting over 80% of non-nuclear/non-offshore grade large modules.
