FEED CABLE SYSTEM FOR A TOWER OF A DRILLING MACHINE

摘要

A drilling machine includes a feed cable system which operatively couples a rotary head (106) with a tower, wherein the feed cable system (130) includes first and second pull up cables (132a and 132b) and an equalizer bar (120), wherein the equalizer bar is coupled to the first and second pull up cables. The drilling machine includes a slack take up device (110) which couples the equalizer bar to the tower. The equalizer bar drives the rotary head to be held in a level position so that it is restricted from tilting.
