Lifting Beam for Handling Modular House in Construction Sites
The simple lifting beam used to lift the integrated house must have a simple structure, controllable cost, and be safe and reliable.

Design Principles
Lightweight: Deadweight ≤ 15% of the module weight (e.g., to lift an 8-ton module, the deadweight of the lifting beam ≤ 1.2 tons), reducing crane load.
Versatile: Adapts to common modular housing module sizes (3-4 meters wide, 6-12 meters long), with an adjustable lifting beam (with fine-tunable hook spacing) preferred.
Low Cost: The main structure utilizes Q235B steel (I-beams/channels), with welding replacing precision machining.
Structural form selection:
1. Fixed lifting beam: Standard size modules, Main load-bearing beam + fixed lifting lug, simple structure.
2. Adjustable lifting beam: Multi-size modules, Main load-bearing beam + sliding lugs (bolt adjustment spacing)
3. Truss type hanging beam: Large span modules, I-beam + diagonal bracing reinforcement, light weight and high strength
