1.6. STRUCTURE AND STABILITY OF THE LIFT TRUCK
1-28
SPEED AND ACCELERATION
If a stationary object is not subjected to external force, it will remain stationary. In the same way, if a moving object
is not subjected to external force, it will continue to move at the same speed. This is called inertia.
Because of inertia, a force is applied towards the rear when the lift truck starts to move, and is applied towards the
front when the lift truck stops. If the brakes are applied suddenly, there is danger of a large force being applied
towards the front which may make the lift truck tip or the load to be expelled.
When the lift truck is turned, a centrifugal force is applied to the outside from the center of the turn.
This force pushes the lift truck to the outside and makes it tip. The range of stability to the left and right is
particularly small, so it is necessary to reduce speed when turning, in order to prevent the lift truck from tipping. If
the lift truck is traveling with a raised load, the position of the overall center of gravity is high, so the danger of
tipping to the front, left, or right becomes greater.
