Black Snake Short Kevlar® Recovery Strops
Recovery in underground longwall operations, mining vehicles and skid mounted equipment
The endless, parallel lay configuration of KEVLAR® fibres around the steel eyes is perfect for the construction of very short, high strength strops. Two leg systems using Black Snake KEVLAR® recovery strops have been used extensively in the underground coal (typically Longwall) operations throughout Australia. The lightweight and rugged construction suit the harsh, dirty conditions underground and the low elongation of the KEVLAR® and damping qualities of the rubber cover ensure low recoil in the event of over-loading the strop.

- 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.
