Lifting straps, sometimes referred to as tie-down straps, are typically used for holding down heavy equipment or cargo in overhead lifting or transportation. In order for the straps to function effectively, they are typically used with various hardware materials, including buckles, end fittings, and fasteners.
In order to ensure that lifting straps are able to perform to their expected ability, it is important to have them inspected periodically. Knots, holes, and tears are obvious indications that the straps may have become worn and could need to be repaired or replaced. In addition, it is important to have the straps inspected to ensure there is no broken stitching present in the stitch patterns.
It is also important to be aware that over time, UV damage can also occur to lifting straps. Indications that UV damage may have occurred include apparent bleaching or when the webbing of the straps has a stiff feel.
In addition, it is important to note whether there may be small particles that have become embedded within the webbing of the lifting straps. This is vital due to the fact that even small particles can result in deterioration of the webbing.
Many times, lifting straps are used in environments where they may come into contact with alkali, acid, or other chemicals. This can result in burnt areas in the webbing. When such areas are present, they can result in restricting the integrity of the material.
Lifting straps may also need to be replaced if there are any pits, cracks, or corrosion present from the fittings used on the straps. Any unusual wear patterns that appear on the webbing near where the fitting comes into contact with the strap could also indicate the need for repair or replacement.
If any of the above issues are noted, it is important for lifting straps to be taken out of service. Ideally, tie down straps should be inspected before being placed into service and each time prior to use.
