Abstract:
A method for engaging a loading unit with a machine supported on a floor surface, comprising the steps of:providing a loading unit having rollers for supporting the loading unit on the floor surface which are vertically displaceable relative to the loading unit such that displacement of the rollers raises and lowers the loading unit;providing, on a side of the machine, first and second fixing pieces that are vertically displaced from one another;providing, on a side of the loading unit, first and second mating pieces that are vertically displaced from one another so as to be simultaneously respectively engageable and disengageable with the first and second fixing pieces to permit cantilevered support of the loading unit from the side of the machine tool;vertically extending the rollers to elevate the loading unit relative the floor surface and effecting engagement of the first and second fixing pieces with the first and second mating pieces; andretracting the rollers upward while the first and second fixing pieces are engaged with the first and second mating pieces such that the rollers are removed from contact with the floor surface and the loading unit is supported off the floor by engagement of the first and second fixing pieces with the first and second mating pieces.
