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.
