Avoid situations danger to life
Prevent dangerous situations by seriously taking care of the following precautions:
- Never work with an untested clamp.
- Keep at a distance when lifting and never stand under the load.
- Do not use the clamp if damaged; have the clamp repaired by Gunnebo Lifting fi rstly,
or by a recognised mechanical repair centre. If in doubt, please consult your dealer.
- Never lift more than one beam or load at a time.
- Never lift beams that are heavier than the working load limit (W.W.L.), as indicated on the clamp
and the test certifi cate.
- Do not attach the CSS clamps to any other parts but bulb profi les (HP profi les EN 10-204)
- Do not lift beams or strips smaller or bigger than the jaw opening, as indicated on the clamp
and the test certifi cate.
- When simultaneously operating a number of lifting clamps facing each other, use lifting slings or
chains which are of suffi cient length to ensure that the angle between the slings or chains never
exceeds 60°.
- When simultaneously operating a number of lifting clamps side by side, use a lifting beam
(equalizer) and lifting slings or chains of suffi cient length to ensure that the lifting shackles on the
clamps are never subjected to a lateral load of more than 10°.
- Do not place the clamp on tapered or conical sections of the beam to be lifted.
- Make sure that the clamp(s) is/are positioned so as to balance the load when it is being lifted.
- The clamp is only suitable for use in normal atmospheric conditions.
Safety precautions
- Ensure that the lifting shackle can never be subjected to 10° 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 working 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 accordance
to the guidelines as described in 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 the very same reason, use only original Gunnebo Lifting components.
- The CSS bulb screw clamps may be mounted onto a bulb profi le with a hardness of up to
345 Hb (37 Rc). Please consult with your dealer if harder steel types are used.
- If you are using a CSS bulb screw clamp, please observe the following additional inspection duties:
Make sure that the size of the bulb profi le matches the range of the bulb screw clamp.
- 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.
