Inventory and production

Wire rope slings are used to lift, lower, pull and secure loads. Any uses not described are not permitted without the manufacturer’s prior permission.

All work involving lifting equipment poses a potential risk to life and health when done incorrectly. It is therefore important that persons involved in lifting operations have the training and expertise required to execute the operation safely and securely. Only lifting equipment with a valid certificate may be used. Lifting gear must always be inspected both before and after use in order to identify any damage that may have occurred. All equipment must be inspected at least once every 12 months by an Enterprise of Competence.

Remember to always read the manual before use.
Manuals you can find on our website.

Please note the following temperature limitations:

- Equipment with aluminium ferrules and wire rope with a fibre core may only be used in the temperature range -40°C to 100°C*.
- Equipment with aluminium ferrules and wire rope with a steel core may only be used in the temperature range -40°C to 150°C*.
*Note that some components such as hooks, shackles and master links may be limited to temperatures no lower than -20°C. Please contact us if in doubt.

Please note the following regarding chemical reactions:

Wire rope slings must not be exposed to acid or acid vapours. Exposure may cause the material to become brittle.

The following applies to the wire’s bending diameter:

Minimum bending diameter inside soft eye (U-lift) must be 3 × the diameter of the wire.

Minimum bending diameter outside soft eye (U-lift) must be 6 × the diameter of the wire.

Choker hitches reduce the WLL by 20%

Safety elements and precautions for a lifting operation:

Never exceed the working load limit (WLL).

Never stand or walk beneath a suspended load. Notify your colleagues that you are about to start a lifting operation.

Notify all surrounding persons that a lifting operation will start.

Always use the personal protective equipment required at your place of work.

Avoid yanking and sudden impacts, as this will increase the overall strain on the equipment.

Avoid sharp edges. Use padding if necessary.

Be aware that the load may rotate slightly due to the strain.

Determine the load’s centre of mass, carry out a trial lift and adjust the slings to correct any imbalances detected during the trial lift.

Always be conscious of where you want to put down the load, and keep the destination tidy.

When using wire slings never exceed the angles stated on the sling and the certificate. Contact your supplier for more information.

We recommend using a spreader when lifting long loads.

The thimble or eye should always slip easily onto the crane hook. No force should be used.

Never place the load on the lifting equipment. If the equipment gets stuck under the load, do not use a crane, forklift truck or similar to pull it free.

The lifting equipment has a stated temperature range and limitation. Check the table for your equipment and always be within the limitations.

Wire slings should not be exposed to acid substances or fumes.

Wire rope slings should be stored on a rack in a dry and suitable location. It should not be stored on the ground where it easily can be damaged.

If it is to be stored for a period of time, it should be cleaned and protected from corrosion with suitable oil or grease.

Periodic examination may only be carried out by an Enterprise of Competence.
Such inspections should be carried out at least once every 12 months.

Pay particular attention to the following during inspection:

• that the markings on the equipment are clearly visible.
• deformation and wear on ferrules and thimbles.
• deformation, rust and heat damage on equipment components such as links, rings, hooks, shackles etc.
• thread fractures.
• wear, kinks, crush damage or core displacement on the wire rope.
• rust.
• heat damage, e.g. as a result of welding spatter.

When repairing the equipment, only use components manufactured to the same standard. Repairs must only be carried out by an Enterprise of Competence

NB! Long link chains must never be used for lifting.

Please note the following temperature limitations:

Grade 80 and grade 100 chain slings must only be used in the temperature range -40°C to 200°C. However, the equipment can often be used in temperatures of up to 400°C but with a reduced working load limit. Please contact your retailer or other Enterprise of Competence for more information.

*Please note! some components such as hooks, shakles or master links, may have a limited temperature range down to only -20°C. If in doubt contact us.

Never shorten a chain sling using knots. Instead use shortening hooks or clutches.

Always be conscious of where you want to put down the load, and keep the destination tidy.

Never place the load on the lifting equipment. If the equipment gets stuck under the load, do not use a crane, forklift truck or similar to pull it free.

Chain slings should be stored on a rack in a dry and suitable location. If they are to be stored for a period of time, they should be cleaned, dried and protected from corrosion with a thin oil, for example.

Periodic examination may only be carried out by an Enterprise of Competence.

Pay particular attention to the following during inspection:

• that the markings on the equipment are clearly visible.
• deformation, rust and heat damage to the chain and components.
• twisting and elongation of the chain.
• for cracks and gouges on the chain and components.
• functional defects on components.
• the functionality of the hook latch.
• locking pins and collets on couplings.
• wear to the materials, maximum 10%.
• rust on the chain and components.
• heat damage and welding spatter.

All work with lifting equipment can potentially be hazardous. It is therefore important that all personnel involved have the necessary training and competence to perform the operation in a safe manner. Only lifting equipment with a valid certificate should be used. Lifting equipment must be inspected both before and after use for any damage that may have occurred during use. All lifting equipment must be periodically examined by a competent person at least every twelve months.

Remember to read user manual prior to use.
User manuals are available on our web site.

Fibre rope slings are suitable for use and storage in the following temperature ranges:
Manila, Sisal, Hemp and Polypropylene: -40°C to 80°C*
Polyester and Polyamide: -40°C to 100°C*
Acera HMPE: -40°C to 70°C*
•    Be aware that some components such as hooks, shackles and masterlinks can be limited to -20°C. Contact us if you are in doubt.

Lifting equipment made of natural or man-made fibres are vulnerable to cuts and abrations, protection should therefore be used between the equipment and sharp edges. When storing or drying, the slings should be kept out of direct sunlight or other sources of UV-radiation. Wet slings should be hung up to dry at ambient temperature. At low temperatures ice formation will take place if moisture is present. This may act as a cutting agent and an abrasive causing internal damage to the sling. Further, ice will lessen the flexibility of the sling, in extreme cases rendering it unserviceable for use. Frozen slings should therefore not be used, but hung up in a suitable place to dry.

Be aware of the following regarding chemical resistance:
a)    Polyamide: virtually immune to alkalis;  however, they are attacked by mineral acids
b)    Polyester: is resistant to mineral acids but is damaged by alkalis
c)    Polypropylene: little affected by acids or alkalis and is suitable where the highest resistance to chemicals other than solvents is required.
d)    Manila, Sisal and Hemp: degraded by acids, alkalis and certain organic solvents.
e)    HMPE: is resistant against most industrial consentrated acids, bases, oxidants and organic solvents at room temperature.
Links and other fittings in grade 80 material should not be used in acidic conditions. Contact with acids or acidic fumes causes hydrogen embrittlement to grade 80 materials.

Minimum contact diameter in the eye of the sling must be greater than 2 × rope diameter. Angle in loaded soft eye must not exceed 30°
Minimum contact diameter outside the eye, for example using basket hitchøft, must be greater than 8 × rope diameter.

Minimum contact diameter for endless slings; 8 × rope diameter.
 

Safety during use:
•    Never exceed the WLL stated on the equipment.
•    Never stand or walk underneath hanging loads. Always make your colleagues aware that you are starting a lifting operation.
•    Always use the mandatory personal protective equipment required by your employer.
•    Snatch or shock loads should be avoided as this will increase the forces acting on the sling.
•    Avoid sharp edges, use protection as required.
•    The load should not rest on the slings as this could cause damage. Never attempt to pull out slings that are stuck beneath loads with i.e a fork truck or crane.
•    Never drag the sling along the ground, this can cause damages to the rope.
•    Be aware that the load might rotate when it is being lifted.
•    Determine where the center of gravity of the load lies. Make a trial lift and adjust the slings if the load is unbalanced.
•    When lifting loang loads, use of spreader bar is recommended.
•    Thimble or soft eye must always fit the crane hook. Do not force it to fit.
•    Ensure that the sling is not unecessarily twisted or knotted.
 

When not in use, slings should be stored in clean, dry and well ventilated conditions, at ambient temperature and on a rack, away from any heat sources, contact with chemicals, fumes, corrodible surfaces, direct sunlight or other sources of ultra-violet radiation. Fibreslings should be kept clean to avoid wear in fibers, they can be cleaned by soaking in cold water.

Periodic examination shall only be carried out by an enterprise of competence. Intervals for periodic examination can be decided by competent person, but shall in any case not exceed 12 months.
