Jervis B. Webb Company—a subsidiary of Daifuku Webb Holding Company—offers the 300TT (Tunnel/Tugger) SmartCart AGC. This automated guided cart moves products on an assembly line or transports goods throughout a plant or warehouse. It can tow up to 4,000 pounds, carry up to 2,400 pounds and is available with a 1-1/4ʺ diameter pop-up pin that allows trailers to be towed from underneath (referred to as tunneling). This allows for automatic coupling and decoupling of trailers, increasing flexibility within the assembly or warehouse operation. The Model 100TT, a smaller version of the 300TT, can handle loads of up to 1,950 pounds and moves products and materials on a smaller scale.
