hook from descending to far allowing the clamp to open under the weight of the hook, or, in the

case of an unprotected crane hook, its descending from the lifting eye. When suspending the

clamp directly on the secured crane hook attention must be given to ensuring that the crane

hook can move freely in the lifting eye. Ensure that the crane hook and other material is

protected.

„ 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.

„ 10A clamp is a device that must be clean when used. Dirt has an adverse effect on the

operation and also on the reliability of the clamp. When cleaning the clamp care should be

taken to ensuring that gripping surfaces are at all times clean, dry and free of oil and grease.

Regular cleaning will enhance the life and reliability of the lifting clamps. To clean the gripping

surfaces, 3M Scotch-brite and LocTite SF 7063 are recommended.

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 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 pressure pads (W) for wear and defects. The pressure pads should be undamaged and

free of moisture, dirt, grease and oil. If needed, clean them. 3M Scotch-brite and LocTite SF

7063 are recommended.

„ Check the body (N) en the jaw for damage, cracks or deformation (this may indicate

overloading).

„ Check the lifting eye (D) and camsegment shaft (G) for readily detectable wear and/or damage.

„ Check the spring (M). The spring must have a reasonable spring force when pressing on the

hoisting eye (D) in closed position of the latches (A and B, fig. 2).

„ Make sure that no iniquities such as steel splinters, steel shavings etc. can get into the interior

of the clamp during storage and/or use of the clamp.

„ 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.

„ There is no minimum working load required.

The pressure pads are the most critical parts in the clamp and require extra attention during inspec-

tion. Ensure that there are no pieces of the friction material missing as this could diminish the grip.

If more than 5% of the friction surface is damaged, the pressure pad should be replaced. On the

inside of the front cover illustrations have been included of damaged and worn (rejected) pressure

pads. In doubtful cases an authorised repairer should assess the clamp.

How to operate the clamp

IPNM10 lifting clamps are suitable for the positioning, lifting, turning and vertical transport of (stain-

less) steel, aluminium, Glare, carbon and plastic panels and structures without damaging the panel

surfaces.
