A lift-gate is a device used to raise and lower items from ground level to the level of a tractor trailer.
Freight companies deliver items on a tractor trailer which is approx 56 inches above the ground. These trailers are designed to load and unload at a loading dock or with a fork-lift. If your delivery location does not have a loading dock or fork-lift and the item is too heavy to remove from the trailer by hand, then you may need a lift-gate. It is ideal for deliveries to residential areas, as well as commercial areas that have no docks like stores.
