CrosbyIP IPNM10 Lifting Clamp User Manual

Instruction

Overview

General

You have chosen a CrosbyIP lifting clamp.

CrosbyIP lifting 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.

CrosbyIP provides a 10 year warranty for its clamps. To keep CrosbyIP lifting clamps in optimum condition and keep warranty, regular maintenance is important. Preventive maintenance and repair shall be carried by a repairer authorized by CrosbyIP. In order to benefit from this warranty programme and for more details on maintenance procedures, please consult www.thecrosbygroup.com/resources/crosbyip-10 -year-guarantee for more information.

Please read and understand these instructions before using the lifting clamp

It is not permitted to stay in the danger zone of the load. Ensure that the load remains on the ground when turning. No changes may be made to CrosbyIP clamps. Never straighten, attempt to bend or heat treat parts.

Safety precautions

Proper instruction for the personnel is of vital importance. This will contribute to maximum reliability in the working environment.
IPNM10 clamps may be applied per piece, per set or several at the same time for the lifting of plates.
Ensure that each clamp receives its proportionate share of the load. When using two clamps or more, a spreader beam is recommended.
Contact your CrosbyIP Customer Service Centre before using this clamp for plates and constructions that have a radius.
Temperature: the operating temperature is between –20 ºC (–4 ºF) and 70 ºC (158 ºF). For other temperatures contact your CrosbyIP Customer Service Centre.
There are restrictions for operation in special atmospheres (e.g. high humidity, explosive, saline, acid, alkaline).
Loads: For proper application of the clamp consult the load diagrams 1.
Ensure that all attachments between lifting eye and crane are properly fitted, secured and coupled.
For each lift only one plate may be transported or lifted.
When the crane hook or attachment is too large and/or too heavy, use properly sized CrosbyIP 5000 stinger assembly or a chain sling with D-shackle of 75 cm (30 inch), with a strength that corresponds to the W.L.L. of the clamp. This will, when setting the load down, prevent the 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.
A 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.
The clamping yaws may not be placed on sloping or conical surfaces. Contact your CrosbyIP Customer Service Centre for assistance in selecting a clamp suitable for bevelled plates.

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). Press when the latch lever (A) is closed on the lifting eye (D). There should be clearly apparent spring tension. The clamp should, when the lifting eye is released, return to the closed position without problems.
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 inspection. 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 (stainless) steel, aluminium, Glare, carbon and plastic panels and structures without damaging the panel surfaces.

**See illustrations 3 – 7 for part reference.
How to operate the clamp

**

Open the clamp by pulling the latch lever (A) towards the jaw (3).
Place the clamp securely on the plate so that the jaw of the clamp rests on the plate (E) (4).
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 (5).
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 (6).
The clamp may now be used again immediately or put away in opened or closed position
