When it comes to moving goods vertically, few things can beat a forklift. If you're moving things horizontally through a facility, tuggers and towing vehicles do it quicker and more effectively. Less manpower is needed to move the same quantity of materials, and it takes less time, too.
You can do in one trip what it would take several trips to do with a fork truck or pallet truck. Plus, you can drop off portions of the load as you go without having to unload and reload pallets of materials. Just unhitch the trailer or cart being left at a station and then re-hitch the remaining trailers and carts back to the tug. Deliver to several locations, or even pick up as you go.
There are many kinds of towing vehicles from simple tugs that you walk behind to people carriers that tow, as well. Choosing which towing vehicle to use depends on distance, function and load size.
