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.
