Abstract
A hammer-ripper system for use with the mounting on the boom arm, of an excavator/backhoe, of a conventional hydraulically-operated hammer fitted with a 'shortened' chisel. A 'ripping-type' device like a chisel tooth mounts to a lever with its pivot point attached to the side of the hammer. One end of the lever extends to be impacted by under the shortened chisel, while the other end extends inward. Thus, the tooth end can be placed under embedded boulders and used to hammer (using the transmitted reciprocating action of the hydraulic hammer), and pry or break up the boulders from underneath with the combined hammering and ripping action.
