Safety Instructions - pewag SVW Mode D'emploi

- 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 of sufficient dimensions to allow the clamp to move freely in the hook. Also inspect the lifting eye for
visible wear and/or damage. At the attachment point of the clamp, the object to be lifted must be completely free of
contamination, such as lubricants, dirt, mill scale, and oil. If used, check the clamping blocks for wear and defects.
Make sure that the clamping blocks are completely free of contaminations and are kept dry and undamaged. Inspect
the clamp and the frame for visible damage and for ease of opening and closing. If this is not the case, the clamp must
be removed for thorough inspection purposes. Check that the spindle is free of dirt, and clean it if required, using a
steel brush. If everything is in order, the clamp may be used for lifting.

4. Safety Instructions

Safety First! Guarantee your personal safety and that of others by carefully reading the following safety
instructions 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 (1x) a year by pewag austria GmbH or by a recognised
mechanical repair and service centre. See also Chapter 8 – Overhaul. No structural modifications may be made to the
clamps (welding, grinding).. Contact pewag austria GmbH for further information.
Avoid life-threatening situations
E
Avoid life-threatening situations by complying with the following guidelines:
• Never work with an untested untested clamp or clamps with an expired test certificate.
• Keep a distance when lifting and never stand under the load.
• Do not use the clamp if damaged; have the clamp repaired by pewag austria GmbH, or by an authorised mechanical
repair centre. If in doubt, please contact your supplier.
• Never lift more than one beam at a time.
• Never lift beams that are heavier than the safe working load limit (WLL), as indicated on the clamp and the test
certificate.
• Do not lift beams or strips smaller or bigger than the jaw opening, as indicated on the clamp and the test certificate.
• When simultaneously operating a number of lifting clamps arranged in a row, use lifting slings or chains which are
of sufficient length to ensure that the permissible lifting angles are not exceeded.
• When simultaneously operating a number of lifting clamps arranged in parallel, use a lifting beam (equaliser) and
lifting slings or chains of sufficient length to ensure that the lifting eyes on the clamps are never subjected to a
lateral load of more than 15°.
• Do not place the clamp on conical sections of the beam to be lifted.
• Remove any contamination, grease, oil, dirt, corrosion, etc. from the beam at the point where the clamp is to be
attached.
• Make sure that the clamps are positioned so as to balance the load when it is being lifted.
• All clamps are only suitable for use in normal atmospheric conditions.
• Do not attach the BSW clamps to any other parts but bulb profiles (HP profiles EN 10-204).
Safety precautions
• Ensure that the lifting shackle can never be subjected to lateral load of more than 15°.
• 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 working order before further use.
• Lifting clamps are not suitable for creating permanent joints.
• The clamp should be subjected to preventive maintenance on a monthly basis in accordance with the guidelines
(see Chapter 5 – Maintenance)
• Do not modify the clamp (by welding, grinding, etc.), as this can adversely affect its operation and safety, thereby
nullifying any forms of warranty and product liability.
• Use only original pewag components
• Any improper use of the clamp and/or failure to observe any directions and warnings in these safety instructions
concerning the use of this product may endanger the health of the user and/or bystanders.
5. Lifting
• Check whether the working load limit (WLL) of the clamp is not exceeded.
• Attach the lifting clamp to the hoisting mechanism, by one of the following means::
- 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 of sufficient dimensions to allow the clamp to move freely in the hook.
• Check whether the clamp shows any visible damage.
Application of the SVW/SVSW/SVSUW lifting clamp
• Open the clamp by using the threaded spindle.
• Position the jaws as far as they will go over the beam or strip, ensuring that the clamp is positioned so as to balance
the load when it is being lifted.
• Close the clamp by reversing the threaded spindle as far as it will go (hand-tight).
• Lift gently and check whether the clamp is slipping.
• If the clamp continues to slip consult Chapter 6 – Maintenance.
• Make sure that the load is in a stable position, before taking the clamp off the plate.
Application of the BSW lifting clamp
• Open the clamp by means of the thread spindle.
• Position the clamp completely onto the bulb profile, in such a way that the bulb falls into the recess of the clamp
and the flat side of the bulb profile faces the spindle side.
• Close the clamp by fully (i.e. finger tight) closing the thread spindle. Mount the hoisting element onto the lifting
shackle and start lifting gently. Make sure the clamp does not shift. If the clamp shifts or if the load becomes
unbalanced, repeat the above.
• When the load has reached its destination, lower the crane hook until the clamp is fully unloaded. This can be
verified by the slackness of the hoisting chain and a free movement of the lifting shackle of the clamp. Take the
hoisting element from the lifting shackle while holding on to the frame. The bulb screw clamp is removed from the
construction by loosening the thread spindle.
6. Maintenance
For optimum safety, please check the general condition of the clamps at least once a month. See Chapter 7 –
Disassembling/Assembling. Stop using the clamp if:
• the clamping halves are split or deformed, in particular the jaws
• the lifting shackle is visibly deformed
• the shackle pins are visibly deformed
• the spring pins are missing
• the threaded spindle is visibly deformed
• the threaded spindle is dirty and/or damaged
• there is too much room in the spindle nuts
• the marking on the clamp is no longer legible
Depending on the defects noted, the clamp must be dismantled and cleaned as per Chapter 7 "Disassembly/
Assembly". Or have the clamp overhauled by pewag austria GmbH or by an authorised mechanical repair centre.
(see chapter 8 – Overhaul). If in doubt consult your supplier.
BSW
BSW screw clamps are a safety tool which must be clean before use. If the clamp is dirty, it is best to clean it with
diesel or petroleum. It must then be dried using compressed air. It is also possible to dry the clamp with a towel.
For an optimum service life and safety, it is recommended to oil the pivots after cleaning and drying. Ensure that the
clamp surfaces are clean. It is recommended to submit the clamp to a thorough annual investigation. For this purpose,
the clamp must be dismantled by a mechanical repair centre authorised by pewag austria GmbH. Maintenance
and tolerance lists are available to be delivered on request. If it is suspected that the clamp is overloaded, have it
checked promptly by pewag austria GmbH or by an authorised mechanical repair centre. If the clamp is confirmed
to be overloaded, it must be removed from service for inspection and/or repair. It is not permitted to attach accessory
parts, repair or use heat action. Depending on the fault, the clamp must be disassembled and cleaned (see Chapter
7 - Disassembling/Assembling). You may also have the clamp overhauled by pewag austria GmbH or an authorised
mechanical repair centre.
7. Disassembling/Assembling
Disassemby of SVW/SVSW/SVSUW
Important! Mark the individual elements and their mounting positions during disassembling to ensure that during
re-assembling they are mounted in the correct order and in the correct positions. The safety clamps can be easily
disassembled for cleaning and inspection purposes. Please make use of the following sequence (see construction
drawing on page 25):
• Open the clamp to its full extent.
• Remove the retaining pin (9) and the spindle head (6).
• Remove the retaining pin (8) and the link pin (7).
