- 2. ATTEMPT TO LIFT MORE THAN ONE PLATE IN THE CLAMP
- 3. LOWER FROM VERTICAL TO HORIZONTAL OR VISE-VERSA UNLESS THE CLAMPS HAVE BEEN DESIGNED FOR THAT PURPOSE
- 4. OBLIQUELY LOAD VERTICAL CLAMPS
- 5. PUT PACKING BETWEEN THE PLATE AND THE JAWS OF THE CLAMP

- 2. Check the clamp is directly over the centre of gravity of the load
- 3. Ensure the clamp is fully locked or tightened onto the plate before lifting
- 4. Inspect plate clamps before use and before placing into storage
- 5. Take great care to ensure the plate is fully supported before attempting to release the clamp
- 6. Store and handle clamps correctly, always clean and dry before storing
MAINTENANCE AND SERVICE INSPECTIONS
Vertical plate lifting clamps should be regularly cleaned and moving parts lubricated, unless suppliers instructions indicate otherwise. In the case of Clamps with jaws lined with friction materialcare must be taken to ensure no lubricant comes into contact with the friction material
Regularly inspect the plate clamp and if any of the following are suspected or apparent then refer the clamp to a competent person for examination and repair if possible:
- Wear
- Damage/distortion to jaws
- Frame opening out or cracked
- In-secure, worn of bent pins,bolts etc.
- Worn friction grip material
- Bent or unsatisfactory acting locking lever
- Tight or bent or damaged clamping threads
- Corrosion
- Illegible markings
PLEASE NOTE;
Teeth of jaws must not be re-sharpened or re-cut unless this has been approved by the maker.
