Forklift Operation - Maintaining the Stability Triangle
Amongst the key basic discussions with lift trucks is taking into consideration the stability triangle and the center of gravity. Among the most difficult things for an operator of a lift truck to determine is the importance of maintaining their center of gravity in their stability triangle.
The Stability Triangle
A forklift has a 3-point suspension system. The stability triangle is formed when imaginary lines are drawn between these three points. The operator needs to make sure that the center of gravity, which is created, together with the equipment and his load, remains in the stability triangle to be able to prevent the forklift from losing balance and tipping over.
Centers of Gravity
How do you define the center of gravity? When in regards to utilizing a lift truck, we have to be concerned not only with the load's center of gravity but as well with the combined center of gravity. This includes the lift truck and the load it is picking up.
The center of gravity of the load is defined as the load center. The load center can be more easily detected in a uniform load situation, such as a bale. A uniform load on a 48 inch long pallet, for instance, would have the load center at 24 inches. This is a common load center for many lift trucks with smaller capacity. However, if a load is not correctly centered, like with items which are not symmetrical, maybe an engine for example, then great caution and care should be taken in order to gauge the center of gravity.
Furthermore, the lift truck has it's own center of gravity. This shifts each and every time the lift truck carries a load. Once the load is lifted, the center of gravity shifts forward. A lot of care must be taken to be able to maintain the center of gravity within the forklift's stability triangle. This occurs by following the numbers and not raisin more than the maximum allowable, given the center of the load. As well, the load center should be taken into consideration. Be really careful whenever raising the load, the load center moves forward too.
If the stability triangle is respected and the center of gravity is maintained, the operator and all workers and pedestrians nearby could stay much safer. This would truly ensure balanced loads, a balanced machinery and safer for everyone.
