SAFETY INSTRUCTIONS

Remember: safety first! Especially where your personal safety and that of the immediate
onlookers is concerned. Carefully read the following safety instructions before using your
new TNMK safety lifting clamp.
Ensure your own safety and continue to benefit from our product safety by having the
clamp inspected, tested, and, if necessary, overhauled at least once a year by Terrier Lifting
Clamps BV or another recognised mechanical repair and service centre. See also Section 8 –
Overhaul. It is not permitted to make any constructive modifications to the clamps, for
example by means of welding or grinding.
Please contact Terrier Lifting Clamps BV for further information.
TEMPERATURE
The operating temperature of the Terrier TNMK lifting clamps lies between –10°C (14 °F) and
+60 ºC (140 ºF). Please consult with your dealer if other ambient temperatures are applied.
LOADS
Because of their deep jaws, TNMK lifting clamps are especially suited to the hoisting of split
plates. Never place the clamping blocks onto tapered or conical surfaces. If the crane hook
is not secured, and/or if it is very large and heavy, always use a chain sling with D lock and
a length of approximately 75 cm (30 inch) and with a strength matching the safe work load
(WLL) of the clamp. This will prevent the crane driver from lowering the hook too far when
putting down the load, which might cause the hook to disconnect from the lifting shackle.
When attaching directly onto a secured crane hook, make sure the crane hook is able to
move freely within the lifting shackle.
AVOID SITUATIONS INVOLVING RISK OF LIFE
Avoid situations involving risk of life by observing the following directives:
- Never operate an untested lifting clamp.
- Always keep a distance during the hoisting operation and never stand underneath the
load.
- Do not use the clamp if it is damaged. Have the clamp repaired by Terrier Lifting Clamps
BV or another recognised mechanical repair and service centre. When in doubt: contact
your supplier.
- Never hoist more than one plate at a time.
- Never hoist loads heavier than the safe work load (WLL), as is clearly indicated on the
clamp and the certificate.
- Never hoist loads that are thicker or thinner than the clamp opening, as indicated on
the clamp and the certificate.
- When using more than one lifting clamp at the same time, opposite each other, provide
lifting slings or chains of a sufficient length to ensure that the angle between the slings
or chains does not exceed 60 degrees.
- When using more than one lifting clamp at the same time, next to each other, use a
trussed hoisting girder (equalising traverse girder) and sufficiently long lifting slings or
chains, so that the lifting shackle of the lifting clamp is never subjected to a lateral load.
- Never place the clamp onto tapered or conical parts of the load to be hoisted.
- Remove all grease, oil, dirt, corrosion and contamination from the plate at the point
where the lifting clamp is to be attached.
- The clamp is only suitable for use in normal atmospheric conditions.
