ABSTRACT:
A restraining arrangement for limiting the separation of a feed table having a pivot pin and a positioner block of a mobile track drill. The restraining arrangement includes a first constraint device positioned on the positioner block and a second constraint device secured to the feed table. The first constraint device, consisting of a bushing having a pair of extending ears, is retained within a pair of female constraint members each having a recessed groove. The recessed groove formed in each of the pair of female constraint members is sized to receive the extending ears to allow the bushing and the female constraint members to rotate relative to each other while limiting the separation between the feed table and the positioner block along the rotational axis of the pivot pin.
