Most winches are rated to pull a vertical load...
as in your case 3000 lbs it should lift 3000 lbs
vertically... so when you induce a drag weight it will
pull MUCH more than the rated lift weight... I use
a 1500 lbs winch to pull my car up a pretty good angle
on my ramps.............. but I guarantee your 3000
lbs winch will pull your 3400 lbs car up a set of ramps
all day long
