Be careful
You have already been given some good advise here, but let me give you some anyway.
Be careful!
- - Remember to block the wheels (more than one and please do block in both directions) when lifting your vehicle.
- - Do not crawl under your vehicle when it is liftet by your jack.
- - Kinetic (elastic)/(snatch) straps/rope can hold a lot of energy.
- When using a kinetic strap/rope, you must use a strap/rope designed for the energy you are going to apply to it.
Kinetic straps stretch around 20%, Kinetic ropes around 30%.
- For light duty; 4 to 5 or so times your rescue-vehicle weight. (20K#)
Start with 1 yard of slack and do not go faster than nessesary. If it does not do the job, try again with more speed. Better to go several times than to break something.
- For heavier duty (serious stuck); 6 to 7 or so times your rescue-vehicle weight. (30K#)
You can start with more slack to gain more speed, but remember that the energy in that strap is huge.
- Never use a worn strap/rope. If it breaks it may very well kill someone.
Keep people clear out of reach of the strap if it breaks.
- Use only rated hardware and recovery points.
- Do not cheap out on this gear. Cheap stuff may kill you or someone you care about.
- Never hook up to a point you are not sure will hold.
- Always check if someone else is hooking up. Too many cowboys out there.
- Never interconnect two kinetic straps/ropes with metal hardware.
- Never interconnect two kinetic straps/ropes of different strength.
- Never use a non kinetic strap/rope in a kinetic recovery.
- Tow straps are for towing, not recovery. They are not strong enough.
Enough for now
PS: Please be careful!
