Difference Between Ordinary& Heavy Crane Steel Workshop - Knowledge

1. Independent crane girder system: Separate crane beam welded on column bracket, not shared with roof beam to avoid long-term vibration deformation. 2. Thickened high-strength steel: Q355B/Q460 welded H box column, thick flange and web to bear heavy dynamic load...

Difference Between Ordinary& Heavy Crane Steel Workshop
1. Independent crane girder system: Separate crane beam welded on column bracket, not shared with roof beam to avoid long-term vibration deformation.

2. Thickened high-strength steel: Q355B/Q460 welded H box column, thick flange and web to bear heavy dynamic load.

3. 10.9 grade high-strength bolt full connection: All key nodes adopt friction high-strength bolts, prevent loosening under equipment vibration.

4. Fatigue welding treatment: Full penetration groove weld, UT non-destructive testing to eliminate internal crack hidden danger.

5. Vibration isolation design: Add damping support under heavy forging, stamping equipment to reduce frame resonance damage.
