Abstract
A gripping apparatus for resisting sliding of a drilling machine in first and second directions during drilling operations is provided. The gripping apparatus is pivotably mounted on the anchoring assembly of the drilling machine. The drilling machine includes a reciprocating drill mounted on the boom thereof. During operation of the drilling machine, the reciprocating drill generates thrust and pullback forces which tend to move the drilling machine in the first and second directions, respectively. The gripping apparatus for resisting sliding of the drilling machine in first and second directions during drilling operations includes first and second gripping mechanisms which are moveable between a first disengaged storage position and a second support surface engaging, work position. Each of the first and second gripping mechanisms include a plate from which a plurality of teeth extend, the teeth being for gripping the support surface, and a plurality of arms which are perpendicular to the plate and which have holes therethrough for mating with a fastener to pivotably attach the gripping mechanisms to anchoring assembly. The first gripping mechanism is pivotably mounted on a front …
