Check the operation of the torsion spring (M). If damaged, the camsegment

is not kept in position and can cause hooking of the chain on the back of the
clamp.

scale because this can cause damage of the magnets and decrease of the
holding force.
The camsegment is the most critical part in the clamp and requires extra attention during
inspection. Ensure in any event for good light during inspection. Observe the following
rules during every inspection:
Camsegment: Reject when the sharpness of one tooth is compromised for 50% or more.
This type of clamp can prone to deformation of the hole in which the chain
(D-shackle) impinges, resulting in the hole becoming oval. When that is the case the
clamp should be removed from service immediately.
Deformation in this part is mainly due to exceeding of the maximum side loading
angle of 15°. The maximum loading angles are displayed in the loading diagrams 1.
Some illustrations have been included on the inside of the front cover of damaged
and worn (rejected) pivots and camsegments with explanations. In most cases
however the areas of damage are much less extensive. In doubtful cases an
authorised repairer should assess the clamp.

1.3 how to operate the clamp
IPH10 lifting clamps are suitable for horizontal lifting and transport of non-sagging steel
plates, beams and structures. The IPH10 clamps are kept in place after positioning by
pretension (0,5 & 1) or by magnets (2, 3, 4, 5, 6, 9 & 12 IPH10(J) models).
See illustrations 4 to 6 for part reference.
1. Place the clamps on the plate and exercise pressure, so that the inner side of the
jaw rests against the plate (E) (4).
2. Tension the cables or chains with the crane hook, while the inner side of the jaw
rests against the plate (E) (5).
3. The load may now be lifted, paying careful heed to maintaining constant tension
on the chains and/or cables.
4. 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.
5. The clamp may now be removed from the load. A crowbar may be used placed
between the ridges of the body. This will allow the clamps to be simply turned
away under the plate (6).
