Abstract

The present invention provides for excavating apparatus (10) which can comprise a vehicle (12) having excavating means in the form of a pivotal cutting boom (16) pivotably mounted by way of mounting means (20) on the vehicle (12). The cutting boom (16) has an endless cutting chain (24) drivingly mounted thereon and the boom (16) is pivoted relative to the vehicle (12) so as to vary the depth to which a trench (36) is current. In seeking to cut a trench (36) having a level floor irrespective of any undulations in the surface (14) upon which the vehicle (12) travels, a sensor (30) is associated with the apparatus (10) and is arranged to receive a reference signal (34).
Any variation in the location at which the reference signal (34) impinges on the sensor (30), for instance due to the passage of the vehicle (12) up an incline, serves to determine the angle at which the cutting boom (16) extends from the vehicle (12) and so vary the depth to which the trench (36) is cut.
In order to achieve an accurate relationship between the movement of the position at which the signal (34) impinges on the sensor (30), and the corresponding movement of the boom (16), the sensor (30) is mounted by way of mounting means (32, 38) in such a way that it can move relative to the cutting boom (16) along an arcuate path defined by arcuate guide means (40) having a centre of curvature that corresponds to the axis of rotation of an idler (22) about which the cutting chain (24) travels.
