Safety Instructions; Thsk; Safety Precautions - Terrier FHX Gebrauchsanleitung

clamps should always be used in pairs, or multiples thereof. In the latter case, however,
preferably with a load equalising beam.
Provided that the steel plate of plates do not bend (deflect), one or more plates can be
hoisted at once per lift. When pairs or multiple clamps are used, each damp should carry
en equal part of the load.

SAFETY INSTRUCTIONS

Safety First! Guarantee your personal safety by carefully reading the following safety in-
structions first.
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 B.V. or a recognised mechanical repair and service centre. See also Chapter 8 - Over-
hauling. Contact Terrier Lifting Clamps B.V. for further information.
AVOID SITUATIONS DANGEROUS TO LIFE
Prevent dangerous situations by seriously taking care of the following precautions:
- Never work with an untested clamp.
- Keep your distance when lifting and never stand under the load.
- Do not use the clamp if (it has been) damaged; have the clamp immediately repaired by
Terrier Lifting Clamps BY or a recognized mechanical repair centre. If in doubt consult
your supplier.
- Never lift more than one plate or a package of plates at a time (except the THSK).
- Never lift plates heavier than the working load limit (W.L.L.), as indicated on the clamp
and in the test certificate.
- Do not lift plates which are thicker or thinner than the jaw opening, as indicated on the
clamp and in the test certificate.
- When using a number of lifting damps at the same time, please provide lifting slings or
chains of a sufficient length to ensure that the angle between the slings or chains never
exceeds 60°.
- When simultaneously operating a number of lifting clamps time side by side, please use
a lifting beam (equalizer) and lifting slings or chains of a 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 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.
- Ensure that the damp(s) is (are) positioned so as to balance the load when it is being
lifted.
- The surface hardness of the plate must not exceed 37 HrC (345 Hb, 1166 N/mm
the TNMH).
- The clamp is only suitable for use in normal atmospheric conditions.

SAFETY PRECAUTIONS

- Ensure that the lifting shackle can never be subjected to 15° 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 occurs, check whether the clamp is in good work-
ing order before using it.
- Lifting clamps are not suitable to be used as permanent joints.
- The clamp should be subjected to preventive maintenance on a monthly basis in accord-
ance to the guidelines as described in Chapter 6 - Maintenance.

- Do not modify the clamp (by welding, grinding, etc.), as this can adversely affect its ope-
ration and safety, thereby nullifying any forms of guarantee and product liability.
- For the very same reason, use only original 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 endanger the health
of the user and/or bystanders
The following additional safety precautions are applicable to the FHX, FHSX FHX-V,
TNMH TDH and THSK model
The clamps can be loaded laterally at a maximum angle of 15°, only when they are not
loaded more than the maximum W.L.L. and the permitted top angle. The capacity of the
clamps has been calculated on basis of a maximum top angle of 60°. In case of situations
with larger top angles, then the WL.L. should be reduced proportionally, according the
following loading drawing.With shored up usage, a maximum top angle of 60° is applica-
ble and the W.L.L. is 50% of the maximum permissible working load. The environmental
temperature for use of the standard lifting clamps is between minus 40 and +100 °C.
For the TNMH the environmental temperature for use is between minus 40 and +50 °C.

- Check whether the working load limit (W.L.L.) of the clamp is sufficient for the load cre-
ated in the lifting situation. Note: The working load limit (WWL.) is shown on the lifting
clamp.
- Attach the lifting clamp to the hoisting mechanism either by means of a:
- safety shackle directly to a crane hook,
- coupling link or D-shackle,
- sling or chain, if necessary in conjunction with a coupling link or D-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. Check whether the cam opens and
closes smoothly.
