Forklift Operation - Maintaining the Stability Triangle
The stability triangle and the center of gravity is one of the important basic operating factors. Among the hardest things for an operator of a lift truck to determine is the importance of maintaining their center of gravity within their stability triangle.
The Stability Triangle
To describe it simply, a forklift has a 3-point suspension system. When imaginary lines are drawn between these three points, the stability triangle is created. The operator should make sure that the center of gravity, which is made, together with his load and the machinery itself, remains within the stability triangle to be able to guard against the forklift losing balance and tipping over.
Centers of Gravity
How is the center of gravity defined? When in regards to using a lift truck, we must be concerned not only with the load's center of gravity but as well with the combined center of gravity. This comprises the load that is being picked up and 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 example, will have the load center at 24 inches. This is a common load center for lots of smaller capacity lift trucks. However, if a load is not correctly centered, like with things which are not symmetrical, perhaps an engine for example, then a lot of caution and care must be taken in order to gauge the center of gravity.
The lift truck has its own center of gravity, that shifts each and every time the lift truck carries a load. When the load is raised, the center of gravity moves forward. A lot of care must be taken in order to maintain the center of gravity within the stability triangle of the forklift. This occurs by following the numbers and not lifting over the maximum allowable, given the center of the load. As well, the load center should be considered. Be aware that whenever lifting the load, the load center also shifts forward.
The operator and everybody else who works close-by or in the nearby vicinity, could stay much safer if the center of gravity is maintained and the stability triangle is respected. This would guarantee a balanced machine, balanced loads and safer for everybody.
