A liftgate fee refers to an additional charge imposed on a shipment when the unloading process necessitates the use of a liftgate, also known as a tail lift. This fee is incurred when the size or weight of an item exceeds the capacity for manual handling, requiring the assistance of a mechanical device attached to the rear of a delivery truck. The liftgate fee covers the cost associated with the use of this specialized equipment and ensures the safe and efficient unloading of the shipment from the vehicle to ground level. It is typically applied to shipments that require the convenience and support of a liftgate for successful delivery.
