Why APPI:  When a tired, old winch they had been using to position rail cars of lumber in their pressure treating retort failed for the last time, Jim Burton, the plant manager for Southeast Wood Treating, Ltd. (SEWT) came to us looking for a replacement.

His application required two winches, one at each end of a 250 foot long track with a 70 foot long pressure treating chamber in the center of it.  There are two 65 foot long cars on the track that are hooked together so that when one is pulled out one end of the retort the other is pulled in from the opposite side.

Chosen for this job were two of our WN8500 winches with 10 hp motors to provide his required line speed.  Unlike the previous units, our Columbia winches were provided without brakes so they could be back driven when line is being pulled off them by the winch at the other end of the track.  This arrangement saves valuable time and more importantly, ends the need for a person to walk down the tracks while pulling the wire off the winch drum each time the cars were being moved.

Please contact us if you would like more information about these particular positioning winches or any of our other products and services.
