Abstract: A fork lift for a truck may have at least one mounting beam for pivotally supporting a fork lift mast on a truck frame. The fork lift may extend well below a level of the truck bed to enable engagement of palletized loads resting on the ground by the forks of the fork lift. The mast and fork of the fork lift may be adjusted by removably attaching a pivot connection of the mounting beam to the mast at a selected position along the mast. Attachment elements on the mast may be formed by one or more attachment structures or points. The pivot connection may be attached directly to the mast or may be attached via an attachment bracket having a bracket attachment mechanism that may include one or more attachment elements similar to those on the mast for mutual attachment at a desired height.

Abstract: A fork lift, and especially a fork lift for a truck, may have structure on a forklift carriage for selectively receiving any of a variety of attachment tools. Alternatively, an assembly may be secured to the carriage and the assembly may provide the structure for selectively receiving the attachment tools. The structure may include a bolt and lever mechanism for selectively securing and releasing the attachment tools. A method may include selectively securing any of a variety of attachment tools including, but not limited to, a trencher, an auger, a backhoe, and a hydraulic breaker. These attachment tools may be connected to a hydraulic system for control of the attachment tools. The method may include the preliminary steps of locking the forklift against movement along a mast and insertion of fork tips in pocket(s) supported in the truck.

Abstract: A fork lift for attachment to a truck frame of a truck, include A first mounting beam carried by the truck frame, a detachable attachment mechanism connecting the mounting beam to the truck frame, the detachable attachment mechanism extending through a truck body of the truck, a fork lift mast pivotably connected to the mounting beam, and a tilt actuator connected between the mounting beam and fork lift mast.

Abstract: A fork lift for a truck may have at least one mounting beam for pivotally supporting a fork lift mast on a truck frame. The mounting beam may be mounted in a bed of the truck via other structural members and bolts that extend through the members, bed, and truck frame. The fork lift may extend well below a level of the truck bed to enable engagement of palletized loads resting on the ground by the forks of the fork lift. The fork lift may have hydraulics including pumps, solenoids and motors that may be supported in a tool box that also helps to secure the mounting beam. An electric over hydraulic control system enables remote control from within the cab of the truck. Fork position during stabbing of a pallet may be viewed on a monitor in the cab, with the monitor operatively connected to one or more cameras.
