Fork lift for trucks, methods, and associated devices
First Claim
1. A fork lift for attachment to a truck frame of a truck, comprising:
- first and second mounting beams carried by the truck frame;
a plurality of detachable attachment mechanisms connecting the first and second mounting beams to the truck frame, the plurality of detachable attachment mechanisms extending through a truck body of the truck;
a fork lift mast assembly pivotably connected to the first and second mounting beams;
a fork lift carriage carried by the fork lift mast assembly, the fork lift carriage being repeatably slideable between raised and lowered positions relative to the fork lift mast assembly;
a tilt actuator connected between the first mounting beam and fork lift mast assembly; and
a tool box positioned on the first and second mounting beams, wherein the tool box includes first and second channels which receive the first and second mounting beams, respectively, the tool box being positioned at an opposite end of the first and second mounting beams from the fork lift mast assembly.

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.
