ABSTRACT:
This invention relates to a motion multiplier for use with an extendible boom forklift vehicle wherein a light-duty fork carriage is linked to the motion multiplier attached to a heavy-duty fork carriage to allow motion of the light-duty forks to translate to a multiplication of motion of the heavy-duty forks. The motion multiplier is a cylinder, piston and rod assembly which, when utilized between a light-duty fork carriage and a heavy-duty fork carriage, allows for movement of a particular distance of the light forks to be translated into movement of twice that distance by the heavy forks. The motion multiplier allows for a heavy-duty fork carriage to be superimposed upon and operated by a light-duty fork carriage without any need for disconnecting and reconnecting hydraulic systems.
