A powered hand truck and dolly system for ISO containers, comprising:
- a powered hand truck having:
- a chassis having a first end, a second end opposite the first end, and a drive system mounted on the chassis;
- a container engagement mechanism extending from the first end of the chassis, the container engagement mechanism having:
- a lower housing;
- a right boom having a proximate end rotatably mounted to the lower housing and a distal end having an ISO compliant twist lock connector attached thereto;
- a left boom having a proximate end rotatably mounted to the lower housing and a distal end having an ISO compliant twist lock connector attached thereto;
- and
- a height adjustment mechanism for adjusting a height of the container engagement mechanism relative to the chassis;
- and
- at least one dolly having:
- a pair of closely spaced wheels;
- a frame extending between the wheels, the frame including a base;
- and
- an upright member extending upward from between the two wheels, the upright member being attached to the base of the frame so that the upright member provides for an adjustment of the height of the frame relative to the wheels, the base of the frame having an ISO compliant twist lock connector attached thereto;
- wherein the powered hand truck and the at least one dolly are adapted for connection to the ISO container by connection of the twist lock connectors to mating twist lock receptacles below corners of the ISO container in order to lift and move the ISO container;
- wherein the lower housing comprises:
- a horizontal bottom plate;
- a front vertical plate;
- a rear vertical plate, the horizontal bottom plate, the front vertical plate and the rear vertical plate forming a channel, the proximate ends of the right boom and the left boom being rotatably mounted to the lower housing within the channel and the distal ends of the right boom and the left boom extending beyond the channel;
- a lower vertical tube extending vertically from a center of the bottom plate, the lower vertical tube being connected to the height adjustment mechanism to allow the container engagement mechanism to be lifted and lowered by the height adjustment mechanism;
- an upper vertical tube having a top, the upper vertical tube being telescopically mounted within the lower vertical tube;
- a lifting system connected to the upper vertical tube for extending and retracting the upper vertical tube;
- and
- an upper horizontal square stabilizer bar mounted to the top of the upper vertical tube, the stabilizer bar being adapted for contacting an upper portion of the ISO container to stabilize the ISO container.
