BLACK SNAKE KEVLAR® RECOVERY STROP
The endless parallel lay configuration of the Kevlar® fibres, coupled with high strength steel eyes encased in a thick, rubber cover, creates lightweight, rugged and very high break strength strops. From 4 metres up to 20 metres in length and ranging from 10-500 tonnes break strength, Black Snake Kevlar® Recovery strops are suitable for most recovery situations in mine operations and heavy duty applications. With over 22,000 Kevlar® Recovery Strops sold, Black Snake Kevlar® Recovery strops provide a practical and proven alternative to wire rope, chain or fibre rope/round-sling/webbing straps.
-
Ultra high strength to weight ratio, flexibility for easy use and handling
-
Low elongation of 4%, low recoil properties from the Kevlar® fibres and the thick cover provide a safe energy damping feature in case of over-loading the strop during recovery
-
Abrasion/cut resistant rubber protects the inner Kevlar® fibres from the elements and keeps out oil, water, mud and dust allowing it to be virtually maintenance free
-
Easy to install with various shaped eyelets available that are sized to fit standard connections. Special thimbles can also be fitted according to customer requirements
-
Individual serial number and embedded RFID for full traceability

Black Snake Kevlar® Recovery Strops are designed for recovery and towing of mining, heavy commercial, and military vehicles and plant.
Black Snakes Kevlar® Recovery Strops are an ideal substitute for heavy and unwieldy chains and wire rope recovery equipment. The low stretch and recoil during the recovery / tow makes the Black Snake safe to use in all conditions.
The rubberized outer coating protects the load bearing fibres from the elements and is more durable than most fibre ropes, synthetic webbing straps or round slings.

Footnote:
- Break strength is the applied load at which the recovery strop fails
- Maximum GVW is the maximum recommended gross vehicle weight of a severely bogged vehicle for a given tow strop
- Severely bogged vehicle is judged as resting on its axles or chassis. The vehicle is being dragged with no rolling of the wheels. Resistance force is 75% of vehicle weight. Weights of strops are approximate and are subject to change without notice.
*All attachments, shackles, hooks must have a greater minimum break strength than the recovery strop
Break Strength denotes the applied load at which the Recovery Strop fails. (i.e.: 50 tonne (f) =490.5kN applied force)
Nominal length refers to the measured length of the strop taken from inside each eyelet.
THIMBLE EYE DIMENSIONS
Light Duty Kevlar® Recovery Strops Typical Eyes
The 10t & 20t MBS Black Snake KEVLAR® range use embedded AS1138 wire rope thimbles. The low elongation properties of the KEVLAR® fibres do not deform wire rope thimbles at these low applied loads. The 30t and 50t MBS Black Snake KEVLAR® range only use AS1138 wire rope thimbles when the knuckles of larger shackles or oversize pins are required.

KEVLAR® Recovery Strops
Custom designed and machined eyes are created from high strength, low alloy steel, hollow bar. A radius is machined onto the inside face of the bore to suit many types of coupling links and pins of appropriately sized shackles.

Custom designed and machined eyes are created from high strength, low alloy steel hollow bar. The bore hole is designed to minimize elongation under very high loads and to suit appropriately large shackles. We are always designing for safety and therefore undersized shackles (Jaw width) will not fit on the machined eyes. For example, a 17t S Grade shackle will not fit a 150t strop.
