3.1 General terms
3.1.1 feller-buncher
self-propelled machine designed to fell standing trees and arrange them in bunches
[SOURCE: ISO 6814:2009, 2.3.2.2]
3.1.2 ground reference plane
GRP hard, flat, horizontal surface on which the machine is placed for measurements
3.2 Terms related to masses
3.2.1 normal operating mass
total mass of the machine as specified, fully serviced, with full fluid levels and a 75 kg operator
3.2.2 maximum operating mass
total mass of the machine as specified, fully serviced, with full fluid levels and a 75 kg operator,including all machine options with either the heaviest undercarriage and track combination or the largest tyre/hydro-inflation combination and the manufacturer’s maximum specified load
3.3.7 overall width
w 1 horizontal distance between two vertical planes parallel to the longitudinal axis of the machine and passing through the farthest points on the two sides of this axis with the felling head positioned as described in 3.3.2
Note 1 to entry: See Figure A.1 and Figure A.2.
3.3.8 tread
w 2 horizontal distance between two parallel vertical planes passing through the centreline of the tires on an axle or the mid-width of the sprocket teeth on a tracked machine
Note 1 to entry: See Figure A.1 and Figure A.2.
3.3.9 loaded tire radius
r 1 vertical distance from the ground reference plane (3.1.2) to the horizontal centre of the axle with the machine at normal operating mass (3.2.1)
Note 1 to entry: See Figure A.1.
3.3.10 angle of articulation
a 1 maximum angle of frame steering movement from the straight-ahead position between longitudinal centrelines of the front and rear frames, measured in degrees
Note 1 to entry: See Figure A.1.
3.3.11 minimum swing circle
d 1 smallest diameter that the outermost point on the machine or felling head will describe when the turntable and/or booms and felling head are swung to their limits with the felling head in its normal swing position and as close to the machine as possible without making contact with a non-rotating structural member
Note 1 to entry: See Figure A.2.
3.3.12 tail swing radius
r 2 maximum described radius from the centre line of rotation to the outermost point of the upper structure with the levelling table, if equipped, parallel to the ground reference plane (3.1.2)
Note 1 to entry: See Figure A.2.
3.3.13 clearance circle
d 2 diameter of the smallest circle that the outermost point on the machine will describe when turning,brakes unapplied, felling head at ground level
Note 1 to entry: See Figure A.1.
