Caution
the max load and load center
distance
The horizontal distance between the centre of gravity of the
load on the forks and the backrest or the front face of the
forks (whichever is shorter) is called the load centre distance.
Maximum load is the maximum load that a forklift truck can
carry at a standard load centre distance. The relationship
between maximum load and load centre distance is
stipulated in the forklift truck's load capacity graph. If the load
centre distance moves towards the front of the forks, the
overall centre of gravity shifts forward. Therefore, the load
capacity decreases.
Caution
Gravity and
stability
Forklift stability depends on the common centre of gravity of
the forklift. When the forklift is unloaded, the centre of gravity
(CoG) remains unchanged. When the forklift is loaded, the
centre of gravity is formed by the combined centre of gravity
of the forklift and load.
The load's centre of gravity depends on whether the mast is
tilted forward or backward, raised or lowered, which means
that the combined centre of gravity also changes accordingly.
The forklift's combined centre of gravity is determined by the
following factors:
–
Load size, weight and shape;
–
Lifting height;
–
Mast tilt angle;
–
Tire inflation pressure;
–
Acceleration, deceleration and turning radius;
–
Driving surface conditions and inclination;
–
