Twin-Path® Sling Warning & User Information
DEATH or INJURY can occur from improper use or care
- Sling users shall be trained Do not use this sling unless you are properly trained.
- Read and follow all instructions and warnings in this manual.
- Check tag to confirm that sling is adequately rated for the load. See page 7 for chart.
- Inspect sling for damage including:
- Missing or unreadable Identification Tag
- Ensure Check-Fast® External Warning Indicator or tell-tail indicators extend past the tag area of
each sling
- If fiber optics are installed, ensure light transmits from end to end
- Holes, tears, cuts, abrasive wear or snags
- Ensure inner red cover is not visible
- Acid or caustic burns
- Exposed core yarn
- Broken or damaged core yarn
- Weld splatter or heat damage
- Fittings that are pitted, corroded, cracked, bent, twisted, gouged or broken
- Any other condition, including visible damage, that causes doubt as to the continued use of the sling
IF ANY OF THESE ARE DETECTED - SLING SHALL BE REMOVED FROM SERVICE IMMEDIATELY
Inspection Frequencies
- All slings and rigging shall be inspected before each use.
- Documented periodic inspections shall be completed at least annually or more frequently depending on service.
- Refer to ASME B30.9 and / or contact manufacturer for recommendations for guidance on service intervals.
USE
- Determine the weight and center of gravity of the load. For special lifts consult manufacturer for additional support and/or suggested products.
- Check the sling tag to confirm that the sling is rated adequately for the load in the manner or hitches that it will be used. Refer to load angle, choke angle and other relevant charts.
Use caution with lifts at angles less than 45° and do not make lifts with slings at less than 30°. When possible, use longer slings to minimize angular tension by increasing the angle. Severe angles can greatly reduce sling strength.
- Check chemical resistance. Twin-Path® slings are generally resistant to common chemicals. Resistances in this chart are based on common concentrations at room temperature. Elevated concentrations and temperatures may affect chemical resistance. Contact Slingmax for more information when using in environments with elevated concentrations of chemicals and/or temperatures.
Some chemicals on this chart (including those rated as “Excellent”) can damage the sling cover. Contact Slingmax® for more information.
4. Be sure warning indication devices are operable.
Do not drag sling over any surface.
Do not expose to damaging chemicals and/or temperatures over 180°F/82°C. Refer to manufacturer for additional information.
5. Select compatible fittings.
6. Center the sling and the load on the hardware being used. Avoid bunching the sling. Do not fold sling, rather, push together.
Do not place the identification tag on the bearing point. The Identification tag should be placed 18-24 inches away from the bearing point and facing away from the load.
To avoid injury, it may be necessary to use multiple persons or an overhead lifting device to lift the slings and rigging.
7. Protect sling from abrasive surfaces, pinch hazards, and edges. Use abrasion protection for abrasive surfaces and cut protection for edges on the hardware or load.
8. Ensure sling paths are smooth in the hitch without any twisting or bunching.
Sling shall not be twisted, tied into knots, or joined by knotting.
9. Equalize the slack by hand. Do not equalize the sling by using the crane or hoist to create tension.
Keep hands clear when the sling is being tightened.
10. Carefully lift the load.
Balance, maintain control and avoid sudden movement or jerking of the load.
Be alert for snagging of the load.
STAND CLEAR OF LOAD AT ALL TIMES.
DO NOT RIDE ON SLING OR LOAD.
STOP THE LIFT IMMEDIATELY if the load does not lift evenly, the external warning indication devices react, or any other observed failure of the rigging is detected.
CARE
Store slings to prevent contact with possible mechanical damage, corrosion, dust, grit and extreme temperatures.
To clean: use mild soap and water and allow to air dry before storing.
Do not machine wash or dry, to avoid damaging the sling.
REPAIR
Field repair is not permitted. Return sling to a Slingmax® Dealer for repairs. Click Here for list of authorized Slingmax® Dealers.
Attempting to repair sling can result in sling failure, load drop, and death or serious injury.
DISPOSAL
Before disposing of Twin-Path® slings, the slings shall be cut in half to prevent inadvertent use.
Waste must be disposed of in accordance with national and local environmental regulations.
CUT AND ABRASION PROTECTION
Slings in contact with edges, corners, protrusions, abrasive surfaces or connecting hardware shall be protected with a material of sufficient strength, thickness and construction to prevent damage. Cut protection shall be rated and labeled for its intended use.
Failure to use proper protection can result in sling failure, load drop, and death or serious injury.
CornerMax® Sleeve is made from tough high performance Fiber that is specifically woven to provide cut protection for a variety of edges and surfaces. CornerMax® Sleeves can be used in many different angles and applications. Rated for 25,000 lbs per inch of sling width.
The CornerMax® Pad creates a “tunnel” of cut protection which is known as the No Touch Zone.
The corner of the load does not come in contact with the pad or the sling. The CornerMax® Pad is specifically designed to be used in 90° angle applications. Rated for 25,000 lbs per inch of sling width.
Synthetic Armor Pads protect slings from abrasion damage that can be caused by contact with rough surfaces such as concrete beams and structures. They are also used to protect finished or painted loads from marring. Synthetic Armor can be made to fit any length or width sling.
The pin area of a shackle can damage synthetic slings. Placing synthetic slings on the pin should be avoided. Shackles may have a sharp edge where the pin goes through the shackle ear. If the sling is rigged on this area, it could become severely damaged. If you must rig on the pin, protect your sling with a Shackle Pin Pad.
TRAINING & RESOURCES
Per ASME B30.9 & OSHA
Sling users shall be trained. Qualifying persons performing rigging functions shall meet the applicable criteria and shall, through education, training, experience, skill, and physical ability, as necessary, be competent and capable to perform the job.

SYNTHETIC SLINGS
Slingmax has been a trusted supplier of high performance synthetic roundslings to the industrial and heavy lifting markets since 1986. Think Twin-Path® slings for all your heavy lifting and rigging needs.
RIGGING ACCESSORIES
The Equalizer Block is used to maintain tension on all legs of the sling during a lift. The Equalizer Block will automatically adjust itself when tension is put on the device from the sling. This was designed specifically for Twin-Path® Extra Slings
WIRE ROPE DESIGNS
Slingmax multi-part wire rope slings are designed for increased capacity and excellent flexibility. The three-part Tri-Flex, nine-part Gator-Laid, and nine-part Gator-Flex grommet have excellent D/d ratios and can be fabricated in shorter lengths.
