Recently scored on a Maasdam Rope Puller. Designed sort of like a come-along, the unique benefit to this thing is you don't need to reset and re-hook every 5 or 10 feet as with a come along. You get a continuous pull for as much rope as you have. 1500 pounds of pulling capacity. Uses 1/2" Dacron rope. Seems pretty well built. I've used mine to skid a good-sized log and am happy with it thus far. Wish I had bought this years ago.
Maasdam Rope Puller w/ 150' of rope.
My next purchase will be an 8-ton come along and hopefully the Hi-Lift Jack can be set aside for the most part.
