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

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 surface of the drum 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 with the drum.
Check the body (N) en the jaw for damage, cracks or deformation (this may
„
indicate overloading).
Check the lifting eye (D) and the lifting eye shaft (H) for deformation.
„
Check whether the W.L.L. and the jaw opening stamped on the body corresponds
„
with the load to be lifted.
1.3
how to operate the clamp
IPDV clamps are solely suitable for the lifting and vertical transport of steel tight head
drums (ISO 15750-2).
See illustrations 3,4,5 for part reference.
1.
Place the clamp in open position over the edge over the drum (3).
2.
Close the clamp by pulling the lifting eye (D) upwards (see arrow P). The clamp
remains in locked position on the drum and is ready for use (4).
3.
As soon as the load is at its destination let the crane hook descend until the clamp
is fully free of load, meaning that the lifting chain is no longer taut and the lifting
eye (D) of the clamp can move freely (5).
4.
Open the clamp by pulling up the grip (X). The clamp can now be removed (5).
