ABSTRACT:
A percussion tool usable as part of a single tool impact device or a multi-tool impact device. In each case, the tool is rotatably driven by a high-torque rotary actuator with the tool being longitudinally splined and received within a correspondingly longitudinally splined hollow drive shaft of the actuator. The tool extends fully through the drive shaft to a rearward end thereof at which is positioned a percussion hammer to provide reciprocating endwise impact to the tool. The tool is held within the drive shaft by a splined lock member which can be rotated between a release position with its splines aligned with the drive shaft splines, and a locked position with its splines misaligned with the drive shaft splines. The device is mountable on a mobile vehicle having an articulated arm. The multi-tool impact devices utilizes six such units in side-by-side relation with the drive shafts of each having a gear which drivable interconnects the shafts to maintain them synchronized and couple them together for the transmission of drive force therebetween.
