1. Description
The rescue sling strop is an orange buoyant rescue device intended for hoist rescue operations.
The rescue sling strop comes in different configurations, depending on operational needs.
The padded section is fluorescent orange with 3 silver SOLAS reflex stripes for easy night spotting,
4 anti slip friction stripes and equipped with a rear towing grip.
Lite Flite rescue sling strops are split in two groups: Open sling strops, and closed sling strops.
Open strop
Primary security are two 45mm webbing risers, with A-rings to fit into the hoist hook. Secondary
security is a yellow webbing slider with a red webbing handle for the casualty to pull downwards
to minimize the distance between the lift straps. The webbing slider forms a double channel,
where one channel is sewn tight enough to ensure the slider cannot be removed from the sling
strop, and the other channel loose enough for the end of the other riser and D-Ring to pass
through in order for the sling to be opened.
Closed strop
Primary security is the 45 mm webbing risers assembled in a A-ring to fit into the hoist hook.
Secondary security is a stainless steel 3-bar slide with 2 webbing toggles for the casualty to pull downwards to
minimize the distance between the lift straps. This is called "TRIPLE-S" = Self Securing System.
For "Man over board" situations the maritime sling strop P/N 60087317 features an extra
internal safety strap assembled with a 50 mm click-in snap for easy fastening.
P/N 60087342 is a special variant of the closed strop, featuring two slings in one. The outer sling
is designed to support the victims legs, giving a sitting position to prevent damages caused by
hypothermia.
1.1 Materials used
Webbing: 45mm polyester webbing, with a tensile strength of 6000 lbs.
Hoist point: One or two stainless steel A-rings, with a tensile strength of 4400 lbs.

3. Definitions Maintenance tasks are often referred to in numerous ways. The definition of terms used in this manual are explained, in short, below. Daily inspection: Rescue sling strops are to be functionally checked by the user prior to each use. Daily maintenance: Rescue sling strops must be cleaned and dried by the user after each use. Annual inspection: Every 12 months, rescue sling strops must be carefully inspected by a qualified technician. Rescue sling strops used in adverse and/or dirty conditions may require more frequent inspection. Qualification can be obtained by participating in a Lite Flite maintenance course. By passing such course, a diploma will be issued. Re- qualification must be performed every 36 months. Maintenance: Maintenance is limited to functional cleaning, drying and functional tests. This will be explained in details in the following paragraphs. Repair: Repair is to be carried out by Lite Flite, or a repair station specifically approved by Lite Flite. Rescue sling strops in the P/N 600873xx series contain no user repairable parts. Overhaul: There is no fixed overhaul cycle for Lite Flite rescue sling strops. 4. Cleaning and drying 4.1 Sewn parts Webbing and all other fabric can be spot cleaned with a mild solution of dish soap and lukewarm (max 30°C) tap water, using a small soft brush. To remove salt deposits, let the rescue sling strop stay in a bath of lukewarm tap water (max. 30°C) for 30-60 minutes, then carefully flush it with cold tap water (max. 20°C) for a minimum of 5 minutes. Rinse until the water from the webbing does not taste salty any more, shake it and allow to dry at room temperature. Buckles, adjusters etc. must be left in open position to allow as much free flowing air around as possible. Do not wring, compress or machine dry the rescue sling strop as this will damage the fibres. 4.2 Hardware Hardware may be cleaned with lint free cotton cloths. Do NOT use abrasives, solvents, acid or caustic liquids as they may damage the anti-corrosion treatment of the hardware. If small stains of oxidation (pre-stage of corrotion) is found, they may be “rubbed” away using a small soft brush and tooth paste. Do not use steel wool and/or chemicals, as this may be harmfull to the surface treatment. Remember to rinse carefully with cold tap water. After rinsing, shake well and allow to dry at room temperature. Page 6 of 10 Rev. 2.5 – 23 July 2021 CMM-25-20-84-600873xx
5. Annual inspection and functional tests Lite Flite rescue sling strops are to be inspected and functionally tested after thorough cleaning. All parts must be inspected visually, following the check list in section 7. Always be methodical when inspecting the assembly and work your way from one “end” of the assembly to the other. Check the Product Log Card for any remarks. 5.1 Webbing Repair or replacement is necessary if your webbing shows any signs of beneath damages: • Damaged or cut edges. Heavy wear and exposed single fibers. • Partial stiffness from UV radiation • Spots from acid (or other aggressive chemicals), rust or mildew. • Excessive soiling • Missing stitches or damaged sewing. • Deformation due to wear or hardware interface. 5.2 Stitch Patterns Repair or replacement is necessary if stitch patterns have broken, cut, worn or missing stitches or threads. Where possible, remember to check all stitch patterns from both sides of the webbing. 5.3 Hardware Repair or replacement is necessary if hardware shows any sign of beneath damages: • Nicks, burrs and sharp edges. • Deformities, cracks and breaks • Missing parts, malfunction, rust or corrosion. • Severe wear and tear. • Scoring, or uneven wear. • Broken or missing components Attention has to be given to: holes, cavities from pitting, and worn surfaces. 5.4 Product label After inspection, check that the product label is readable. If the maintenance is performed by Lite Flite, the label will be replaced by a new label with a new “Next inspection date” printed. Page 7 of 10 Rev. 2.5 – 23 July 2021 CMM-25-20-84-600873xx
