If CrosbyIP clamps are maintained as described in this manual, they will remain in
optimum condition. We believe that CrosbyIP clamps are the most reliable lifting
clamps available. But using reliable tools does not automatically mean that practices
are reliable. The people who work with clamps play an equally important role in reliable
lifting. Ensure that everyone who works with CrosbyIP lifting clamps has been
instructed in the proper application of the clamps.
Inter Product BV provides a 10 year warranty for its clamps. In order to benefit from this
warranty programme and for more details on maintenance procedures, please consult

Please read and understand these instructions before using the lifting clamp.

right position. During the lift it may happen that the flanges of the beam will not
hang in a clear horizontal position. Ensure that you never exceed the thickness of
flange and that the pivot always stays in full grip contact with the profile.

When the clamp is not used again immediately it is advisable to place a piece of
„
carton between the pivot(s) and the camsegments, so that they cannot touch
each other. This to prevent unnecessary damage of the teeth.
Remark: when handling the load, one should ensure that the load and or clamp
„
does not encounter obstacles which could release the load on the clamps
prematurely.
A clamp is a device that must be clean when used. Dirt has an adverse affect on
„
the operation and also on the reliability of the clamp. When the clamp is dirty and
greasy it can be cleaned with diesel oil or petroleum. Then blow dry with air or dry
with a cloth and apply a little lubricant. It is important to ensure that the gripping
surfaces are clean at all times. Regular cleaning will enhance the life and reliability
of the clamps.
1.2 inspection protocols
Prior to every application of the clamp it is important the clamp operator inspects the
clamp for proper functioning.
Attention must be paid to the following (see illustration 2 for part reference):
Ensure that the plate surface with which the clamp is to come into contact is free
„
of scale, grease, oil, paint, water, ice, moisture, dirt and coatings that might
impede the contact of the gripping surface with the plate.
Inspect pivot(s) (C) and camsegment (B) for wear and defects. The pivot(s) and
„
teeth must be sharp and free of dirt.
Check the body (N) and the jaw for damage, cracks or deformation (this may
„
indicate overloading). The clamp must open and close properly (when the
operation of the clamp is stiff or heavy, it should be removed from operation for
inspection).
Check the chain (Z) for readily detectable wear and/or damage. It must be
„
possible to turn the chain freely around the hinge pen (R), between the
camsegments (B).
Check the hinge pen (R) and the camsegment shaft (G) for readily detectable
„
wear and/or damage.
Check the torsion spring (M). Open the clamp by moving the latch lever (A)
„
towards the hand grip (X). There should be clearly apparent spring tension. The
clamp should, when releasing the latch, return without problems to the closed
position.
Check whether the W.L.L. and the jaw opening stamped on the body corresponds
„
with the load to be lifted.
