I purchased a similar 4 wheel per pulley block model,block and tackle from this company , but with 4 wheels in each pulley,sheave unlike this picture that shows two two wheel pulley sheaves, ,back in the 1970s from a hardware store in Colorado, Ive been looking to buy a second 4 wheel sheave one ever since, its packaging stated it was rated at 1000lbs does anyone know who currently sells these? I don,t see the company listed on line yes I pack it in and use it to lift ELK but the one I own is rated at 1000 lbs and while small its lifted dozens of large elk over the years yes theres lots of larger heavier 2 and three wheel per sheave pulley hoists listed, but this ones pocket size light weight high quality and has worked well for decades on dozens of elk. any suggestions on finding a duplicate? and yes the para cords only rated to about 300 lbs but with it having 4 redundant, multiple passes through the pulleys sheaves it lifts a heavy elk rather easily. as you get older and gain experience you appreciate the better tools available, and if you can get one of these they make lifting a large elk up off the ground to field dress it, with less potential for dirt in the meat a far easier proposition.
