General; Operating Principle; Permitted Applications; Safety Instructions - REMA CBKN Série Mode D'emploi

1. GENERAL

Congratulations with the purchase of your new REMA CBK safety beam lifting clamp.
The quality systems of management and services of REMA Holland BV fully comply with ISO 9001
standards. The many years of vast experience are a guarantee of optimum quality and safety. REMA lifting
clamps are made of top quality alloyed steel and fully comply with European standards as laid down in
Machine Directive 2006/42/EG.

2. OPERATING PRINCIPLE

The CBK safety beam lifting clamp has especially been developed for the lifting of steel beams.
A special lifting shackle is used to place the centre of gravity of the beam to be lifted directly beneath the
lifting shackle. This maintains the equilibrium of the beam, once it is lifted. The CBK lifting clamp features a
safety mechanism consisting of a locking device, a tension spring and a lever. Once the lever is operated,
the safety mechanism provides constant pre-tensioning of the cam on the steel plate, thus ensuring that
the clamp does not slip when the lifting force is applied. When a load is being lifted, the clamping force on
the cam is increased by the weight of the load. It also ensures that the clamp will not work itself loose from
the plate when the lifting force is off the clamp.

3. PERMITTED APPLICATIONS

The CBK lifting clamp may only be used for lifting and transporting steel beams (T, UNP, INP, IPE, HE, etc.),
here it is possible to position the clamp on a flat point of contact so that the clamp completely fits on to the
flange of the beam.
Permitted positions for using the clamp are the lifting and transporting of beams from:
- horizontal position and
- vertical position.

4. SAFETY INSTRUCTIONS

Safety first! Guarantee your personal safety 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 a year by REMA Holland BV or by a recognised
mechanical repair and service centre. See also Chapter 8 - Overhauling. Contact REMA Holland BV for
further information.
AVOID SITUATIONS DANGER 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 damaged; have the clamp repaired by REMA Holland BV firstly or by a
recognised mechanical repair centre. If in doubt, please consult your supplier.
- Never lift more than one beam 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 certificate.
- Do not lift beams with flanges thicker or thinner than the jaw opening, as indicated on the clamp and
the test certificate.
- When simultaneously operating a number of lifting clamps facing each other, use lifting slings or chains
which are of sufficient 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 (equaliser)
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 beam to be lifted.
- Remove all grease, oil, dirt, corrosion and mill scale from the beam at the point where the clamp is to be
attached.
- The surface hardness of the beam must not exceed 37 HrC (345 Hb, 1,166 N/mm2).
- The clamp is only suitable for use in normal atmospheric conditions.
