Ш OUTSIDE THE TRIANGLE OF BALANCE, THE
TRUCK TIPS
For
a
lift
truck
to
remain
stable,
the
overall
center
of
gravity
must
be
inside
the
triangle
formed
by
the
contact
points
of
the
left
and
right
front
tires
and
the
center
point
between
the
steering
wheels.
The
triangle
defines
the
area
of
stability
for
the
center
of
gravity.
If the
overall
center
of
gravity
moves
further
forward
than
the
front
wheels,
the
truck
will
tip
forward
with
the
front
wheels
as
the
fulcrum.
if
the
overail
center
of
gravity
moves
outside
the
triangle
to
the
right or
the
left,
the
truck
will
fall
over
in
that
direction.

Axis of lateral
stability
If the center of gravity
W1 moves outward past
the axis of lateral
stability, the truck will
roll.
(As the center of gravity | `
comes closer to the rear
axle, the space between
the centerline of the
{ruck and the axis of
lateral stability narrows,
and the truck will roll
more easily.

m RATED LOAD (LOAD WEIGHT AND LOAD
CENTER)
The load center is the distance from the front face of the forks to
the center of gravity of the load. The rated load is the maximum
weight allowable with the nominal load center.
The Load Chart, showing the relationship between the load center
and the rated load, is attached to the truck as a decal. The rated
load decreases as the load center moves toward the tip of the forks,
and as the overall center of gravity moves forward.
HOW TO READ THE LOAD CHART
The higher the load is raised, and the further forward
from the front wheels the load is moved, the more the
weight of the load increases.
(Slightly heavier loads can be carried with dual tires)
