Abstract

Self-propelled cutting apparatus and related methods are disclosed. An exemplary apparatus includes a frame to which are mounted at least one cutting device and a locomotion device. A control device, coupled to the locomotion device and to the cutting device, is configured to controllably actuate the cutting device to apply a cutting force to a target material and to actuate the locomotion device to move the apparatus relative to the target material. Desirably, the apparatus includes a monitoring device, and the control device is remote to the apparatus, allowing an operator to control operation of the apparatus remotely based on data obtained by the monitoring device. The apparatus has particular utility for use in in situ cutting of pipe, such as in preparation for pipe bursting.
