Safety Precautions - Terrier TS Mode D'emploi

- Do not use the clamp if damaged; have the clamp repaired by Terrier Lifting Clamps B.V.
or another recognized mechanical repair and service center. If in doubt consult your sup-
plier.
- 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.L.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 surface hardness of the plate must not exceed 37 HrC (345 Hb, 1166 N/mm
regard to the TSU-R lifting clamp please notice that the surface hardness of the plate must
not exceed 30 HrC(283 Hb, 945 N/mm 2 ).
- 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 Terrier 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 endan-
ger the health of the user and/or bystanders.
Special note for TS-R/TSE-R/TSU-R/TSEU-R lifting clamp owners
- Use the for TS-R/TSE-R/TSU-R/TSEU-R lifting clamps solely for lifting stainless steel plates
and structures.
- In spite of the considerable mechanical strength of the coating, the clamp must be han-
dled with extreme care! Possible damage due to impacts such as knocks, falls, etc. must
be avoided.

5 LIFTING
- Verify whether the working load limit (W.L.L.) of the clamp is sufficient for the load crea-
ted 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 TS-R/TSE-R/TSU-R/TSEU-R lifting clamps 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.
). With - Close the clamp by turning the lever fully back.
2
- Lift gently to allow lifting force to be applied; check whether the clamp is slipping.
- If the load is slipping, read this Chapter 5 - Lifting again.
- If the load continues to slip, refer to Chapter 6 - Maintenance.
- Make sure that the load is in a stable position before loosening the clamp from the plate.
6 MAINTENANCE
- Check the general condition of the clamp at least once a month.
- Stop using the clamp if:
- when the clamp is difficult to open or closed,
- the body is split or deformed, in particular in way of the corners of the jaws,
- the lifting shackle and/or connecting piece or MP fork (if applicable) are visibly defor-
med,
- the cam and/or pivot teeth are no longer sharp,
- the spring has become stretched or broken,
- the lever locking mechanism has become inefficient or has ceased to work,
- the shackle pins are visibly deformed,
- any retaining pins are missing,
- the keyway groove is dirty,
- the marking on the clamp is no longer legible.
Depending on the defects/malfunctions noted:
- disassemble and clean the clamp (see Chapter 7 - Disassembling/Assembling or have the
clamp overhauled by Terrier Lifting Clamps B.V. or another recognized mechanical repair
center (see Chapter 8 - Overhauling).
