BLACK SNAKE NYLON RECOVERY STROPS
Snatch type recovery and towing of 4WD, light commercial, military and mine vehicles
The Black Snake Nylon Recovery Strop provides a heavy duty, industrial strength alternative to webbing snatch straps and kinetic nylon ropes. The Black Snake Nylon Recovery Strop incorporates nylon strands laid in an endless parallel lay construction into galvanised wire rope thimbles, the entire construction is then covered in a vulcanised, industrial grade rubber. This construction is very robust and has inbuilt protection for the load-bearing fibres along with excellent energy dampening qualities. With other nylon webbing straps, kinetic recovery nylon ropes and even nylon round-slings, the fabric construction make them susceptible to dirt, mud and abrasion damage. The soft eyes are particularly vulnerable to cutting and fraying from shackles, pins and hooks. The Black Snake Nylon Recovery Strop uses embedded heavy duty thimbles to eliminate cutting and fraying of the fibres.
Black Snake Nylon Recovery Strops are ideal for dragging skid mounted equipment and safe recovery of mining/industrial plant. They are also used for the recovery of commercial and agricultural vehicles.
The nylon fibres are encased in a rubber coating protecting them from the elements that over time break down the load bearing fibres. This design makes the Black Snake far more durable than fibre ropes, synthetic webbing or round slings.
Black Snake Nylon Recovery Strops are fitted with Australian Standard 1138 thimbles embedded into the eyes and sized to fit standard connections.
FEATURES OF BLACK SNAKE NYLON RECOVERY STROPS:
- Abrasion/cut resistant rubber protects the inner nylon fibres from the elements and keeps out oil, water, mud and dust allowing it to be virtually maintenance free and making it far more durable than other fabric straps
- A tough, high performance, great alternative to webbing straps
- High strength Nylon 6.6 load core with high strength to weight ratio
- Very flexible and light weight for access into awkward spaces and for attachment devices
- Easy to install with galvanised thimbles embedded into the rubber casing. Perfectly matched with shackles and clevis pins
- Smooth stretch of up to 20% to assist snatch style recovery
- Individual serial number for traceability

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 a vehicle which is resting on its axles or chassis. The vehicle is being dragged with no rolling of the wheels
Resistance force is 75% of vehicle weight.
HIGH STRENGTH, HEAVY DUTY NYLON RECOVERY STROP
Snatch type recovery and towing of medium to heavy commercial, military, mine vehicles and skid mounted equipment
The Black Snake Heavy Duty Nylon Recovery/Tow Strop provides a high break strength, industrial grade alternative to old style recovery equipment. It is far lighter than wire rope or chain of the same break strength and provides a low shock load, kinetic type of recovery. It is particularly suited to operations in harsh environments. In the higher break strengths of 20 tonne through to 100 tonne, the Black Snake Nylon Recovery Strop is far more durable than nylon webbing straps, kinetic recovery nylon ropes and round-slings. The deeply embedded, galvanized, heavy duty steel thimbles eliminate cutting and fraying from shackles, pins and hooks, which present problems with fabric straps and ropes.

*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 measured length of the strop taken from inside each eyelet. Weights of strops are approximate and are subject to change without notice.
