Forklift Operation - Maintaining the Stability Triangle
The stability triangle and the center of gravity is among the key basic operating factors. One of the hardest things for a lift truck operator to judge 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 must make sure that the center of gravity, that is made, along with the machinery and his load, remains within 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 it comes to lift truck operation, we should be concerned not only with the center of gravity of the load being lifted but as well with the combined center of gravity. This comprises the load that is being picked up as well as the lift truck itself.
The load's center of gravity is defined as the load center. The load center can be more easily detected in a uniform load situation, like for example a bale. A uniform load on a 48 inch long pallet, for instance, would have the load center at 24 inches. This load center is very common for many lift trucks with smaller capacity. However, if a load is not centered correctly, like with things that are not symmetrical, perhaps an engine for example, then a lot of care and caution must be taken to be able to estimate the center of gravity.
In addition, the lift truck has a center of gravity of its own. This shifts every time the lift truck carries a load. When the load is raised, the center of gravity shifts forward. A lot of care must be taken to be able to maintain the center of gravity within the stability triangle of the forklift. This occurs by following the numbers and not carrying more than the maximum allowable, given the center of the load. Also, the load center must be considered. Be aware that whenever raising the load, the load center shifts forward too.
The operator and everybody else who works in the nearby vicinity or close-by, could stay much safer if the center of gravity is maintained and the stability triangle is respected. This will truly guarantee balanced loads, a balanced equipment and safer for everyone.
