WARNING
- A free-fall or uncontrolled swinging movement at the crane hook resulting in
objects being struck may cause damage to the clamp. If this occurs, check
whether the clamp is in good working order before using it again.
- Lifting clamps are not suitable for creating permanent joints.
- Preventive maintenance to the clamp should be carried out on a monthly
basis. See Section 6 - Maintenance.
- Do not perform constructive modifications to the clamp (such as by welding,
grinding, etc.). Such modifications may adversely affect its operation and safety.
If you carry out any modifications, you will nullify all forms of guarantee and
product liability.
- This is also the reason to only make use of original REMA replacement parts.
- Any improper use of the clamp and/or failure to observe all directions and
warnings in this user manual concerning the use of this product may endanger
the health of the user and/or bystanders.
- Check the segment's teeth for dirt. If necessary, clean these using a wire brush.
- Make sure the plate is free from grease and dirt in the place where the lifting
clamp will be fastened.
- Open the clamp by means of the lever.
- Position the jaw completely over the plate. Make sure that the clamp is
positioned in such a way that the load is balanced during the hoisting
operation.
5. HOISTING
- Make sure that the safe work load (WWL) and the jaw opening of the clamp
(as indicated on the clamp) agree with the load to be hoisted.
- Mount the lifting clamp onto the hoisting mechanism, either:
- Directly to a crane hook by means of a safety shackle,
- By means of a coupling link or D-type shackle,
- By means of a sling or chain, if necessary in conjunction with a coupling
link or D-type shackle.
Ensure that all attachments have been tested and are of the correct tonnage.
Make sure that coupling links and shackles are large enough to allow the clamp
to move freely in the hook.
- Make sure the clamp has no visible signs of damage.
- Check the lifting shackle and chain for clearly visible signs of wear and/or
damage.
- Check the draw spring. It should demonstrate visible tensile elasticity upon
inspection with the safety lever in closed position.
- Check the clamping blocks for signs of damage and defects (the clamping
blocks should be free from dirt and should be dry and undamaged).
Check the frame and jaw for signs of damage, cracks, and deformation (these
may indicate overloading).
- Using the lever, make sure the clamp opens and closes smoothly (if the
clamp's operation is difficult, do not use the clamp. Have it serviced
immediately).
