The pivot(s) and the camsegment are the most critical parts in the clamp and require extra
„
attention during inspection. Ensure in any event for good light during inspection.
the most common areas of damage: Observe the following rules during every inspection:
Pivot(s): Reject when the sharpness of one ring is damaged or worn for 50% or
more.
Camsegment: Reject when the sharpness of one tooth is damaged or worn for 50% or
more.
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
IP10 - IPU10 lifting clamps are suitable for the lifting, turning and vertical transport of
steel plates and structures.
See illustrations 4-8 for part reference.
1. Open the clamp by pulling the latch lever (A) towards the jaw (4).
2. Place the clamp securely on the plate so that the jaw of the clamp rests
on the plate (E) (5).
3. Pull the latch lever (A) towards the lifting eye (D). The clamp will now close and will
remain on the plate in pretensioned position, allowing lifting to commence (6).
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 and the lifting
eye (D) of the clamp can move freely. To release the load pull the latch lever (A)
towards the jaw, allowing the clamp to be and remain opened (7).
5. The clamp may now be used again immediately or put away in opened position.
This position will protect the teeth from damage (8).
