IPHOZ Horizontal lifting

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.

Check when placing the clamp that slings are not twisted.

It is not permitted to stay in the danger zone of the load.

No changes may be made to CrosbyIP clamps. Never straighten, attempt to bend or heat treat parts.

Clamps suited for stainless steel, must be used only for handling stainless steel, to avoid contact corrosion.

Safety precautions

• Proper instruction for the personnel is of vital importance. This will contribute to maximum reliability in the working environment.
• IPHOZ clamps may be used per pair, per three clamps or with several pairs simultaneously 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.
• Hardness: With the standard clamps it is possible to lift steel with a surface hardness of 363 HV10. For harder steel types contact your CrosbyIP Customer Service Centre.
• Contact your CrosbyIP Customer Service Centre before using this clamp for plates and constructions that have a radius.
• Temperature: the operating temperature is between –40 ºC (–40 ºF) and 100 ºC (212 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.
• Use chains/cables which are longer than the width of the plate to be lifted. IPHOZ clamps may not be used when reeved.
• Several plates may be transported or lifted per lift, only if the plates will not sag.
• IPHOZ lifting clamps may be used for sagging, bended or joggled plates, however in that case no more than one at the time.
• During the tensioning of cables or chains the clamps must remain properly positioned.
• 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 moving parts are lubricated and the gripping surfaces are clean. Regular cleaning will enhance the life and reliability of the clamps.

Inspection 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 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) for readily detectable wear and/or damage (check also the roll pin (P) which locks the camsegment shaft).

• 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 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 damaged or worn 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.

On the inside of the front cover illustrations have been included of damaged and worn (rejected) pivots and camsegments:

1. One complete tooth not sharp and one damaged
   

2. Two teeth damaged for 50%
   

3. One tooth damaged for 100% and one tooth damaged for 50%
   

4. Two rings damaged for 100%
   

5. Interior ring damaged for 100%
   

These areas of damage, precisely as wear, are not covered by the warranty.
In most cases however the areas of damage are much less extensive. In doubtful cases an authorised repairer should assess the clamp.

How to operate the clamp

IPHOZ lifting clamps are suitable for the horizontal lifting and transport of one or more sagging steel plates and structures.

See illustrations 3 – 5 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) (3).
2. Tension the cables or chains with the crane hook, while the inner side of the jaw rests against the plate (E) (4).
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 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 (5).

A reliable clamp, a secure basis for lifting

10 Year warranty preventive maintenance procedure:
Parts should be replaced only when they no longer meet our standards.

10 Year warranty repair procedure:
During every repair service the most critical parts, being camsegment will be replaced and, when necessary, any rejected parts.

For clamps with a Working Load Limit (W.L.L.) of 4,5 ton or more, parts will be replaced only when they no longer meet our standards.

Please consult www.thecrosbygroup.com/resources/crosbyip-10-year- guarantee for more information on maintenance procedures.

Maintenance without 10 year warranty: Annually clamps are subjected to inspection and parts will be replaced only when they no longer meet our standards.

WARNING

• Loads may disengage from clamp if proper procedures are not followed.
• A falling load may cause serious injury or death.
• The clamp shall not be loaded in excess of its rated load or handle any load for which it is not designed. Read instructions in user manual to determine minimum load permitted and proper load thickness.
• Never operate a damaged or malfunctioning clamp, or a clamp with missing parts.
• Clamp not to be used for personnel hoisting.
• Prohibition of handling above persons.
• Do not leave suspended loads unattended.
• Operator and other personnel shall stay clear of the load.
• Do not lift loads higher than necessary.
• Do not make alterations or modifications to clamp.
• Do not remove or obscure warning labels.
• See ANSI/ASME B30.20 BELOW-THE-HOOK LIFTING DEVICES for additional information.
• Read, understand, and follow these instructions and the product safety information in user manual before using clamp.
