Every forklift maintains its balance while carrying a load by using a cantilever system positioned on a fulcrum, which is the machine's front wheel axle. The cantilever system is similar to a simple teeter-totter, a device that also relies on a fulcrum to operate.Know More
According to the Occupational Safety & Health Administration, a balanced forklift is highly stable and capable of carrying significant weight. The fulcrum, or pivot point, is the dividing line between the machine's weight and the load's weight.
Forklift America reports most forklifts indicate their load capacity on their respective data plates. The most important thing to remember when evaluating a load is that every object that is lifted has a center of gravity just as the forklift and load together have a center of gravity. This is why it is crucial for a forklift driver to keep the load within the triangular area between the front wheels, or fulcrum, and rear steering axle. It is this positioning of the load that keeps the loaded forklift stable. Placing the load too far away from the front axle is likely to cause the forklift to tip forward, while placing it too far to either side is likely to cause it to tip sideways.Learn more about Motion & Mechanics
The fixed point on which a lever moves is called the fulcrum. A lever is a simple machine with three parts: effort, load and the fulcrum. The lever would be useless without the fulcrum, as it is the point on which the lever pivots.Full Answer >
A class 2 lever is a lever with the fulcrum or joint at one end, with the load that is being carried in the middle. The effort, which is the object lifting or pulling the lever, is at the opposite end from the fulcrum.Full Answer >
An output arm is the end of a lever that moves the load up when force is applied to the other end of the lever. The upward force that moves the output arm is the output force.Full Answer >
A uniformly distributed load has a constant value, for example, 1kN/m; hence the "uniform" distribution of the load. Each uniformly distributed load can be changed to a simple point force that can be used to determine the stresses in an object.Full Answer >
