Inspections 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(s) 2 for part reference):

„ Ensure that the surface of the concrete pipe section or well 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 tooth with the object.

„ Inspect camsegment (B) for wear and defects. The 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 camsegment shaft (G), hinge shaft (F) and lifting shaft (I) for readily detectable wear

and/or damage.

„ Check whether the W.L.L. and the jaw opening stamped on the body corresponds with the

load to be lifted. When this is no longer readable, remove the clamp from operation.

The camsegment is the most critical part in the clamp and require extra attention during inspection.

Ensure in any event for good light during inspection. In doubtful cases an authorised repairer

should assess the clamp.

How to operate the clamp

IPCC lifting clamps are suitable for vertical lifting and transport of concrete pipe sections & wells.

See illustrations 3 - 5 for part reference.

1. Place the clamps on the concrete pipe (with chain (Z) already attached to the camsegments;

check that chains are not twisted) (3).

2. Tension the cables or chains with the crane hook, while the inner side of the jaw rests against

the edge of the object (4).

Remark: because IPCC clamps are not fitted with a constant pretension system on the cam-

segment (B), it is important to watch the position of the clamps until the chains have tensioned

out. Make sure that the clamps remain in position against the edges of the pipe.

3. The load may now be lifted, paying careful heed to maintaining constant tension on the chains

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 (Z) is no longer taut and the clamp can move freely (5).

5. The clamp may now be removed from the load.
