  • Patent number: 10538399
    Abstract: Container handlers including improved fork assemblies. One embodiment includes a vehicle having a chassis and a hoist apparatus pivotably coupled with the chassis. The hoist apparatus is movable between a stowed position and an extended position with respect to the chassis. The hoist apparatus further includes a pivotable fork assembly. The fork assembly comprises a frame and a carriage movably coupled with the frame. One or more tines are coupled with the carriage. At least one actuator is coupled between the frame and the carriage and is operative to move between a first position and a second position. Movement of the at least one actuator from the first position toward the second position causes the carriage to move substantially parallel to the frame.
