Frequently Asked Questions

What is DitchPig® Kinetic Energy Recovery Rope used for?
  • Used for dynamic vehicle recovery, where vehicles are stuck in mud, sand or snow
  • It’s the safest and easiest product for getting vehicles unstuck

How does DitchPig® Kinetic Energy Recovery Rope (KERR) work?
  • KERR works like a rubber band:
    • It’s very elastic – stretches up to 30% of its original length
    • As the rope stretches, energy is built up and stored in the rope
    • Once the rope reaches maximum stretch, the energy is transferred to the stuck vehicle
    • Like stretching a rubber band: the further it’s pulled out, the harder it fights to draw back to its original length
  • One end is attached to the stuck vehicle and the other end to the pulling vehicle
  • As the pulling vehicle drives forward, it takes up the rope’s slack creating momentum and pulling force
  • Once the rope is tight, it begins to stretch – when it reaches maximum stretch, the stuck vehicle will begin to move, using all of the energy built up from stretching the rope like an elastic band

Why choose DitchPig® Kinetic Energy Recovery Rope over Recovery Straps?
  • DitchPig® Kinetic Energy Recovery Rope:
    • 100% double braid high-tenacity Nylon rope
    • Highest strength-to-weight ratio for recovery products
    • 45% stronger and lighter than wire rope winch line
    • More effective – Stretches up to 30% of its original length, so it stores and transfers more energy
    • Can absorb shock loads effectively
    • With Recovery Rope, a smaller vehicle can recover a larger, heavier vehicle
  • Recovery Straps:
    • Made from Nylon
    • Less stretch: only 10-15%
    • Lower strength-to-weight ratio than Recovery Rope
    • Straps are larger and bulkier than Recovery Ropes with same work load

Why use double diamond braid rope versus twisted rope?
  • Kinetic Energy Recovery Rope:
    • Used for dynamic recoveries, where vehicles are stuck in mud, sand or snow
    • Versatile – KERR can be used as a tow rope, but tow rope cannot be used for recovery
    • Made from high-tenacity nylon, which can stretch up to 30% of its original length
    • Safer for the user and the vehicle – easiest way to get a vehicle unstuck
  • Tow Ropes and Tow Straps:
    • Used for static towing – when the vehicle’s wheels are not stuck
    • Cannot be used for dynamic recoveries
    • Generally made from low stretch materials, like polyester or polypropylene
    • Frequently have hooks at both ends

Why is DitchPig® Kinetic Energy Recovery Rope made from Double Braid Rope?
  • Double Braid rope has a core rope and a cover (jacket) rope
    • Both core and cover are made in a diamond braid pattern
  • Rope cover provides two key benefits
    • Protects the core rope from debris and dirt, which can cause excessive wear and abrasion if it gets stuck between the fiber
    • Carries part of the recovery load, which allows the load to be evenly distributed
  • Some Recovery Ropes are made from Twisted rope:
    • Less rope material used for twisted rope
    • Weaker than double braid – lower strength-to-weight and strength-to-length ratio
    • Easier to damage

How safe is DitchPig® Kinetic Energy Recovery Rope?
  • Recovery Rope is the safest and easiest way to get a vehicle unstuck
  • Tow chains, cables and straps become dangerous whips when they break under heavy load and can cause serious injury
  • Nylon rope is softer than tow chains or straps, so it poses less risk of injury
  • Always take precautions to minimize risk:
    • Bystanders should be at least 50 feet away from the vehicles in all directions
    • Place a filled line dampener or heavy blanket over the rope to minimize whip lash in case it breaks

How to attach a Recovery Rope to a vehicle?
  • Only use a high-strength fixture that can be securely closed
    • Examples include screw-pin shackles or soft shackles
    • Work Load Limit (WLL) should be 3X the vehicles curb weight

Where to attach a Recovery Rope to a vehicle?
  • Look for attachment points on the frame of the vehicle (check owner’s manual)
  • Do not attach to a bumper or ball of a trailer hitch
    • Under load, these can easily be torn off

Other Features of Nylon Rope:
  • Can be used in very low temperatures:
    • Will not lose strength after many hours at -40°F/-40°C (F & C are equal at -40°)
    • Take measures to keep the rope free of moisture at very low temps – moisture can freeze and the resulting ice can damage rope fibers when load is applied
  • Can be used at very high temperatures:
    • Will not lose any strength as the temperature rises
    • Retains all physical properties almost to its melting point at 210°F / 99°C
  • Highly resistant to alkalis, like potash and lye

Things to Avoid with Nylon Rope:
  • Submerged in water for long periods of time:
    • After a long time, Nylon will shrink and can lose up to 15% of its strength
    • In salt water, the salt and minerals can get trapped in the rope fibers and cause internal abrasions
  • Avoid contact with chemicals:
    • Nylon is rapidly attacked by most acids, paints and linseed oil
