Forklift Operation - Maintaining the Stability Triangle
One of the key basic discussions with lift trucks is taking into consideration the stability triangle and the center of gravity. Amongst the hardest things for a lift truck operator to determine is the significance of maintaining their center of gravity within their stability triangle.
The Stability Triangle
A forklift has a 3-point suspension system. The stability triangle is created when imaginary lines are drawn between these three points. The operator must make sure that the center of gravity, that is created, along with his load and the machinery itself, remains within the stability triangle in order to prevent the forklift from losing balance and tipping over.
Centers of Gravity
How is the center of gravity defined? When it comes to utilizing a lift truck, we need to be concerned not only with the center of gravity of the load being lifted but as well with the combined center of gravity. This includes the lift truck as well as the load it is picking up.
The load center is defined as the load's center of gravity. In a uniform load situation, like a bale for instance, the load center can be more easily detected. 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 lots of smaller capacity lift trucks. Then again, if a load is not correctly centered, such as with non-symmetrical things, perhaps an engine for instance, then great caution and care must be taken in order to gauge the center of gravity.
Moreover, the lift truck has it's own center of gravity. This shifts each time the lift truck picks up a load. Once the load is raised, the center of gravity shifts forward. A lot of care should be taken in order to maintain the center of gravity in the stability triangle of the forklift. 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 considered. Be really careful whenever raising the load, the load center moves forward as well.
The operator and everybody else who works close-by or in the nearby vicinity, could stay a lot safer if the center of gravity is maintained and the stability triangle is respected. This would ensure a balanced equipment, balanced loads and safer for everyone.
