What the AI looks for in Lifting Clamps
- Clamp type
- Use vertical clamps for lifting and turning single plates, horizontal clamps in pairs with a spreader for flat plates, and screw clamps for fixed positioning Using the wrong orientation can make the grip release.
- Jaw grip range
- Plate thickness must fall within the clamp's stated jaw opening Gripping outside the range can cause slipping.
- Minimum load
- Respect the manufacturer's stated minimum load Many vertical clamps need some load to bite properly.
- Material hardness
- Stay within the stated maximum plate hardness Hardened plate can't be gripped reliably by cam teeth.
- Lock
- Use clamps that lock closed A slack sling can let an unlocked jaw release.
