Abstract:
1. An extendable gantry, comprising: a base; an extendable transverse bridge, supported on the base at opposite widthwise ends of the base for reciprocating movement along a direction parallel to a horizontal Y-axis of the base, wherein the extendable transverse bridge has an axial length greater than a width of the base while extending beyond and jutting out of two opposite lateral sides of the base in the width direction of the base beyond the supports along a direction parallel to a horizontal X-axis of the base to create waiting areas; and a plurality of movable tool seats, settled on the extendable transverse bridge and designed to reciprocate in the direction of the X-axis along the extendable transverse bridge relative to one another, for carrying tools to be used for processing a workpiece, said extendable transverse bridge including at least one working area to which the tool seats are movable to perform the processing, and wherein ones of the tool seats not being used in the at least one working area are movable to the waiting areas, and wherein one of the waiting areas is of a width to permit two of the tool seats to wait therein next to each other in the X-axis direction.
