Caution
Stable center of
gravity region
In order to make the forklift truck stable, the combined center of gravity has
to be within the triangle formed by contact point of the front left and right
tires and the midpoint of the rear axle.
If the combined center of gravity is on the rear axle, the two front tires will form a fulcrum and the
forklift truck will tilt forward. If the combined center of gravity moves out of the stable center of gravity
triangle, the forklift truck will roll over in the direction towards the combined center of gravity.
Caution
Maximum load and load center
distance
The horizontal distance between the center of gravity of the load on a fork
and the load backrest of the fork or the front surface of the fork (whichever
is smaller) is called the load center distance. The maximum load refers to the
maximum load that the fork can bear at the standard load center distance.
The relationship between the maximum load and the load center distance is shown on the Bearing
Capacity Chart of the forklift truck. If the load center distance moves towards the front fork, the overall
center of gravity will move forward, thus the load has to be reduced.
Caution
Loading
Capacity Chart
The chart shows the relationship between the location of the load center
distance and the maximum load.
Check whether the load and the load center distance are within the
allowable range of the Bearing Capacity Chart before loading. If the load
shape is complicated, the heaviest part should be placed in the center of the fork and close to the load
backrest.
