Abstract
A fork assembly for a forked materials-handling vehicle with a chassis is configured to simultaneously lift at least two inline pallets, each pallet comprising a plurality of bottom boards. The fork assembly comprises a plurality of elongated forks and a plurality of auxiliary rollers. The plurality of elongated forks includes a first fork and a second fork, where each fork has a proximal end and a distal end along a longitudinal axis and the proximal end of each fork is attached to the chassis. Each fork includes a load wheel connected to the fork, and each fork has a length sufficient to lift at least two pallets arranged in an inline configuration. The plurality of auxiliary rollers are rotatably coupled to one or more of the plurality of forks, where the plurality of auxiliary rollers are positioned longitudinally along the length of the fork assembly such that at least one of the auxiliary rollers is on at least one bottom board of a proximal pallet of the at least two pallets when the load wheel has entered the proximal pallet and contacts a bottom board of the at least two pallets.
