Mark Bollig hated hauling out dead pig carcasses from the buildings at his two large hog operations. Even the best carts were a constant hassle.

That's why he asked his inventive brother-in-law Wyman Travis, to create an easier way. Travis came up with what he calls the Swine Building Rail System Kit.

The rail kit fits any building length, suspended from specially-designed brackets every 8 ft. A wheeled trolley carries the carcass.

A hand-held control activates a 12-volt battery-operated hoist.

The kits, which are custom priced to fit your building length, come with the galvanized steel beam, zinc-plated brackets per 8 ft. of track, connectors, nuts, bolts and end stops.

The trolley, hoist and battery assembly are sold separately.

It's easy to use. "Pull the cable out to the pig, wrap it around the pig's back feet and then the pig is winched up and simply push the carcass out of the building using the I-beam that the hoist and trolley are attached to," says Becky Travis, Wyman's wife.
