NOVELTY - The truck (1) has a rechargeable battery pack (23) powering an electric motor i.e. primary electric drive motor, and a battery pack charging unit in electrical communication with the battery pack. An electricity power supply connector is in electrical communication with the charging unit. A direct current (DC)/alternating current (AC) converter is in electrical communication with the charging unit. Another electricity power supply connector is in electrical communication with the converter, and receives an electrical power take off feed from a carrying vehicle.    USE - Electrically powered piggyback forklift truck for mounting on rear of an articulated chassis of a carrying vehicle for transporting goods to and from customer's premises.    ADVANTAGE - The truck provides a useful choice for a consumer and maximizes an amount of operational time between two charging cycles without providing a prohibitively large battery. The truck has more available power, and is operated in a better manner by charging the truck during a set of times. The truck is charged in an improved manner by using a set of smaller batteries, thus reducing weight and size of the truck. The truck avoids the need for modifying the vehicle by providing a charging equipment on the carrying vehicle. The truck is mounted onto any carrying vehicle with a desired mounting arrangement in a better manner, thus providing high flexibility to a set of entities with multiple piggyback forklift trucks and carrying vehicles.    DETAILED DESCRIPTION - The rechargeable battery pack is a lithium ion battery pack. The electricity power supply connector is a female connector. An INDEPENDENT CLAIM is also included for a method for operating a piggyback forklift truck.    DESCRIPTION OF DRAWING(S) - The drawing shows a front perspective view of a piggyback forklift truck.
