Carts are engaged to the towline chain via a towpin. As the chain moves throughout the length of the towline path, the carts are towed along with it. Carts can be manually removed from the towline for offline processing by simply lifting the towpin out of the tow chain. Once complete, the operator will drop the towpin into the track slot to re-engage the cart back to the tow chain. Although straight line pathing is the most common application, users can incorporate diverts and/or merges to route carts along unique paths.
