This basic principle is used for picking up a load. The ability
of the lift truck to handle a load is discussed in terms of
center of gravity and both forward and side stability.
Stability and Center of Gravity
The center of gravity (CG) of any object is the single point
about which the object is balanced in all directions.
Every object has a CG. When the lift truck picks up a load,
the truck and load have a new combined CG.

CG LOAD

CG TRUCK
C.
COMBINED CG
The stability of the lift truck is determined by the location of
its CG, or if the truck is loaded, the combined CG.
The lift truck has moving parts and therefore has a CG that
moves. The CG moves forward and back as the mast is til-
ted forward and back. The CG moves up and down as the
mast moves up and down.

The center of gravity, and therefore the stability of the loa-
ded lift truck, is affected by a number of factors such as
size, weight, shape, and position of the load; the height to
which the load is raised; the amount of forward and back-
ward tilt; tire pressure and the dynamic forces created
when the truck is moving. These dynamic forces are
caused by things like acceleration, braking, turning, and
operating on uneven surfaces or on an incline. These fac-
tors must be considered when traveling with an unloaded
