Abstract:
A trench-digging machine for digging a trench under a structure comprising:a frame for operable connection to a transport machine, wherein the transport machine defines a lengthwise extending axis and extends widthwise between a pair of lateral bounding planes; a digging implement connected to the frame for digging the trench, wherein the frame is connected to the transport machine such that a center-line of the digging implement is capable of being laterally offset from the lengthwise extending axis to a position beyond the respective lateral bounding planes, thereby permitting the digging implement to be placed under the structure; and an attachment plate carried by the transport machine and capable of connecting said frame to the transport machine wherein said attachment plate is oriented at a permanently fixed angle offset from vertical such that said attachment plate faces downwardly at a fixed position.
