Safety cabs and frames
2.0.1.
All agricultural and forestry tractors should be pro-
vided with a safety cab or frame to protect the operator and any
passenger in case of
(a) tractor overturn in any direction;
(b) falling objects; or
(c) displaced loads.
2.1.
Minimum size
2.1.1.
The minimum size of the safety cab or frame after the
deflections likely to be caused by overturn should be as determined
by the following planes:
(a) vertical planes 250 mm on either side of the reference plane 1
extending upwards from the seat reference point* for
300
mm;
(b) parallel planes extending from the upper edge of the planes
(defined at (a) above) to a maximum height of 900 mm above
the seat reference point and inclined so that the upper edge of
the plane on the side on which the deflection has occurred is
at least 100 mm from the reference plane;
(c) a horizontal plane 900 mm above the seat reference point;
(d) an inclined plane perpendicular to the reference plane and
including both a point
900 mm
directly above the seat reference
point and the rearmost point of the seat structure;
