A liftgate in freight is a hydraulic platform attached to the back of a delivery truck that is used to lift heavy items from the truck bed to the ground. It is essential for deliveries to residential locations or locations without a loading dock or forklift to safely unload goods. Freight companies typically require a liftgate for these types of deliveries to ensure efficient and secure handling of shipments, as they are necessary to accommodate locations without proper unloading equipment.
