3 General definitions
3.1 trencher self-propelled crawler or wheeled machine, having rear- and/or front-mounted equipment (3.6) [attachment (3.7)], primarily designed to produce a trench (3.2) in a continuous operation, through motion of the machine; the attachment can be a digging chain, wheel disc, plough blade, or a similar item [ISO 61 65:1 997] 3.1.1 pedestrian-operated trencher trencher (3.1 ) controlled by an operator while walking either along side or in line with the machine 3.1.2 rider-operated trencher trencher (3.1 ) controlled by an operator while riding on the machine 3.2 trench narrow excavation for which, in general, the depth is greater than the width 3.3 spoil earth, rock, and the like removed when making a trench (3.2) 3.4 base machine trencher (3.1 ) with mountings necessary to secure equipment (3.6) as described by the manufacturer’s specifications 3.5 component part, or an assembly of parts, of a base machine (3.4), equipment (3.6) or an attachment (3.7) NOTE — Adapted from ISO 601 6:1 998. 3.6 equipment set of components (3.5) mounted onto the base machine (3.4) to fulfil the primary design function when an attachment (3.7) is fitted NOTE — Adapted from ISO 601 6:1 998. 3.7 attachment assembly of components (3.5) for a specific use and which can be mounted onto either the base machine (3.4) or its equipment (3.6) NOTE — Adapted from ISO 601 6:1 998. 3.8 Base machine dimensions See also ISO 6746-1 for definitions of dimensions. 3.8.1 maximum total height H 1 vertical distance from the ground reference plane (GRP) to the highest point of the base machine (3.4) See figures 1 to 3.
3.8.2 maximum equipment/attachment height H 2 vertical distance from the ground reference plane (GRP) to the highest point of the equipment (3.6) [attachment (3.7)] in their maximum raised position See figures 1 to 3. 3.8.3 maximum width W 1 distance between the farthest points situated on each side of the machine, perpendicular to the direction of travel See figures 1 to 3. 3.8.4 track gauge W 2 perpendicular distance between the longitudinal centrelines of the track sprockets See figure 3. 3.8.5 tread width W 3 perpendicular distance between the tyre longitudinal centrelines See figures 1 and 2. 3.8.6 maximum length L 1 longitudinal distance between the farthest points on the front and on the rear of the machine See figures 1 to 3. 3.8.7 crawler base L 2 perpendicular distance between the centrelines of the driver sprocket axis and the idler sprocket axis See figure 3. 3.8.8 wheel base L 3 perpendicular distance between the lateral centrelines of the front and rear wheels, with the wheels in the straight ahead position See figures 1 and 2. 3.8.9 angle of approach A 1 angle between the ground reference plane (GRP) and a plane, tangent to the forward tyres or tracks and passing through the lowest point of any protruding structure or component (3.5) in front of the tyres or tracks, which limits the magnitude of the angle See figures 2 and 3.
