Abstract:
A system for engaging a loading unit with a machine supported on a floor surface and in combination with the machine, comprising:said loading unit having a loading unit chassis;first and second fixing devices each including:a fixing piece fixedly disposed relative to said machine and at a side of said machine;said fixing piece having a receiving section; anda mating piece mounted at a side of said loading unit chassis and having a configuration for engagement with the receiving section of said fixing piece;said fixing pieces being disposed vertically displaced from one another on the side of said machine;said mating pieces being disposed vertically displaced from one another on the side of the loading unit chassis so as to permit simultaneous engagement with said fixing pieces such that said loading unit is cantilever supportable from the side of said machine; anda bearing structure having rollers for supporting said loading unit chassis on the floor surface, said bearing structure being displaceable relative to said loading unit chassis to permit vertical movement of said bearing structure relative to said loading unit chassis such that said loading unit chassis is vertically displaceable relative to said machine and said floor surface so as to permit engagement and disengagement of said first and second fixing devices and cantilevered support of said loading unit absent said rollers contacting said floor surface when said first and second fixing devices are engaged and said bearing structure and said rollers are vertically retracted upward.
