Safety Precautions; Lifting - REMA CS Série Mode D'emploi

AVOID SITUATIONS DANGEROUS TO LIFE
(see also the section 'How to correctly use vertical lifting clamps' on page 37)
- Never work with an untested or disapproved lifting clamp.
- Always keep a safe distance when lifting and never stand under the load.
- Do not use the clamp if damaged; have the clamp repaired by REMA Holland BV
- or another recognized mechanical repair and service center. If in doubt consult your supplier.
- Never lift more than one plate at a time.
- Never lift plates heavier than the w.w.l., as indicated on the clamp and the test certificate.
- Never lift plates which have a weight less than 10 % the w.w.l indicated on the clamp and test
certificate.
- Do not lift plates which are thicker or thinner than the jaw opening, as indicated on the clamp
and the test certificate.
- Take care when lifting from a non-vertical position. The working load limit (w.l.l.) may be
considerably reduced in these lifting situations.
- When using a number of lifting clamps at the same time, provide lifting slings or chains of a
sufficient length to ensure that the angle between the slings or chains never exceeds 60
degrees.
- When simultaneously operating a number of lifting clamps time side by side use a lifting beam
(equalizer) and lifting slings or chains of sufficient length to ensure that the lifting shackles on
the clamps are never subjected to lateral load.
- Do not place the clamp on tapered or conical shaped sections of the plate or structure to be
lifted.
- Remove all grease, oil, dirt, corrosion and mill scale from the plate at the point where the
clamp is to be attached.
- The clamp is only suitable for use in normal atmospheric conditions.

SAFETY PRECAUTIONS

- As far as applicable, make sure that the lifting shackle or MP fork is never subjected to lateral
load.
- A free-fall or uncontrolled swaying at the crane hook resulting in objects being struck may
cause damage to the clamp. If this happens check whether the clamp is in good working
order before using it.
- Lifting clamps are not suitable for creating permanent joints. -The clamp should be subjected
to a regular maintenance interval on a monthly basis; see Chapter 6 - Maintenance.
- Do not modify the clamp (by welding, grinding, etc.), as this can adversely affect its operation
and safety, thereby nullifying any forms of guarantee and product liability.
- For this reason, only make use of genuine REMA components!
- Any improper use of the clamp and/or failure to observe any directions and warnings in
- these operating instructions concerning the use of this product may endanger the health of
the user and/or bystanders.

5. LIFTING

- Verify whether the working load limit (w.l.l.) of the clamp is sufficient for the load created in the
lifting situation.
- Attach the lifting clamp to the hoisting mechanism:
- 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.
- Check whether the clamp has any visible damage.
- Operate the lever to check whether the clamp opens and closes smoothly.
- Check whether the teeth of the cam are free from dirt and if necessary clean with a steel
- wire brush. Note: the cam of the CUR lifting clamp should only be cleaned with brass brush.
- Remove any grease, dirt and mill scale from the plate at the site of the lifting clamp.
- Use the lever to open the clamp.
- Place the jaws as far as they will go over the plate, making sure that the clamp is positioned so
as to balance the load when it is being lifted.
- Close the clamp by turning the lever fully back.
