Abstract
Apparatus and method for digging deep vertical walled trenches in solid rock such as limestone. The apparatus comprises a base supported by four crawler type traction means. A turntable is translatably carried by the base and in turn supports a prime mover and a pivoted extendable boom including means for rotating the boom about its longitudinal axis. A dual cutter is supported on the end of the thus articulated boom and is assembled so that the outermost cutter teeth are wider than any other part of the boom assembly. The trenching method includes cutting a pair of narrow slots by means of the rock saws and then removing material between the slots.
