Know Your Lift Truck
The fork lift truck is designed to pick up and move materials.
The basic lift truck has a lift mechanism with forks on the
front to engage the load. The lift mechanism lifts the load
so that it can be moved and stacked.
In order to understand how the lift truck can pick up a load,
you must first know some basic things about the lift truck.
The lift truck is based on the principle of two weights
balanced on opposite sides of a pivot (fulcrum). In order for
this principle to work, the load on the forks must be
balanced by the weight of the lift truck and battery. The
weight of the battery is a major part of the total lift truck
weight. The location of the center of gravity of both the lift
truck and the load is also a factor. This basic principle is
used to pick up a load. The ability of the lift truck to handle
a load is discussed in terms of center of gravity and 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
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 forks are extended
or retracted. The CG moves up and down as mast moves
