As a ex army recovery mechanic the formula from memory is weight/2 for mud ---weight/7 for sand --- weight/25 for level ground plus degrees of slope up to 45% then full weight of vehicle, plus 25% of load for frictional losses and safety factor. You can pull anything with your winch providing you know how to do tackle layouts and you have the cable and snatch blocks to enable this.

Where do you want it to pull the 4WD from & to ??
Pulling it along a flat road then no prob. but pulling 1600 K up a steep
embankment then you've got a prob.
The winch had a capacity of 800K, full stop. It'll be great for some jobs but RS for others. You can't expect it to pull a dead weight of more than 800K. Be careful, be wise.Carpe Diem

David,
winches have have two ratings, a lift rating and a pull rating. Which have you quoted?
Usually the pull rating is around double the lift rating. So, if you've the lift rating, then the winch can probably pull 1,600 kgs. But that would be the "maximum safe limit" and whilst you'r truck may weigh 1,600 Kgs, if it is stuck, that friction will increase its effective "weight" (same if you are recovering up-
hill).Be good, or be quick.

David.
You can pull 1600 kg up a 45deg slope in theory, but allowing for friction and other effects 30 deg may be your limit, still very useful, I have pulled a 5 ton tractor back onto its
wheels after it rolled with a 800kg terfor. Eric,
