HOW TO AVOID A TIPOVER; HOW TO SURVIVE ONE
In order for the lift truck to be stable (not
tipover forward or to the side), the CG must
stay within the area of the lift truck stability
base—a triangle drawn between the front
wheels and the pivot of the rear axle. If the CG
moves forward of the front axle, the lift truck
will tip over forward. If the CG moves outside
of the line on either side of the stability base,
the lift truck will tip over to the side.
The capacity of the lift truck is shown on the
capacity chart. It is determined by the weight
and load enter. The load center is determined
by the location of the CG of the load. The load
center shown on the capacity chart is the hori-
zontal distance from the front face of the forks,
or the load face of an attachment, to the CG in
the load. The location of the CG of the vertical
direction is the same as the horizontal dimen-
sion.
Keep in mind that, unless otherwise indicated,
the capacity shown on the capacity chart is for
a standard lift truck with standard backrest,
forks and mast, and having no special-purpose
attachment. In addition, the capacity presumes
the load center is no further from the top of the
forks than it is from the face of the backrest. If
these conditions do not exist, the operator may
have to reduce the safe operating load because
the truck stability may be reduced. The lift
truck should not be operated if its capacity
chart does not indicate capacity.

These factors must be considered when the lift
truck is unloaded as well, because an empty lift
truck will tip over to the side more easily than
a lift truck carrying a load in the lowered posi-
tion.
