The Lewis Chainsaw Winch can lift massive loads like this huge log downed on Vancouver Island in British Columbia. This commercial owner uses Lewis Snatch Blocks to increase his pulling power, and you can see was very successful

Wector8:I am waiting in anticipation for my Lewis Winch to turn up. I could have walked out of the shop with it, but I wanted the 4000lb cable and large Snatch Block to go with it, so we're just waiting for them to come out from Canadia ;-)
