Center of gravity means the point on an object at which all of the object’s weight is concentrated and all of the parts balance each other. For symmetrical loads, the center of gravity is at the middle of the load in terms of the load’s length, width and height. (Figure 10).
What is a center of gravity on a forklift?
When at rest, on level ground, the forklift’s center of gravity is within the stability triangle. But if the forklift is put in motion, or sits on a sloping surface, its center of gravity shifts. Any time the forklift’s center of gravity moves outside the stability triangle, the lift will tip over.
Where is the fulcrum of a forklift ie where is the center of gravity?
The Forklift Fulcrum
The front axle is the fulcrum of the forklift where the counterweight and the load find balance. The only major difference between a forklift and a seesaw, is that the forklift counterweight should always provide more force than the load so the forklift does not tip forward.
How do you find the load center of a forklift?
Load centre is calculated by dividing the length of the load by two. Forklift A is overloaded, as it’s Load Centre is 700mm, which is 100mm in excess of the rating of the forklift.
What is the load center of a forklift?
The load center is the distance from the face of the forks to the load’s center of gravity. Many forklifts are rated using a 24-inch load center, which means that the load’s center of gravity must be 24 inches or less from the face of the forks.
How high should your forks be when driving forklift?
Keep the forks 6 to 10 inches above the ground to avoid potential hazards on the ground. Remember that forklifts are top-heavy. Carry the load low and tilted back.
What is the center of gravity of a load?
The center gravity of a load is the single point on the load at which it can be hoisted perfectly balanced. Some riggers like to think of it somewhat in reverse: it is the point at which all of a load’s weight is concentrated.
When should you drive a forklift backwards?
“Drive backwards if the load obstructs your forward view; but use a rotating seat if you have one. Otherwise the frequent twisting will put excessive strain on your spine.” That, in brief, is the recommendation set out for drivers and operators.
How often should operators inspect their forklift?
Federal OSHA requires that forklift vehicles have to be inspected at least daily, or after each shift when used around the clock. You will find this requirement in the Powered Industrial Truck standard at 1910.178(q)(7).
Can a forklift tip over without a load?
Forklift Safety Rule Two: Don’t tip over. Many untrained operators assume that they can drive faster without a load, but look at the location of the CG with unloaded forks. … On the other hand a loaded forklift is more likely to tip forward with the CG now closer to the front axle.
What happens when the load Centre is increased?
The weight capacity of a forklift attachment is tied to what is known as the Maximum Load Moment, which is when the load center distance increases, changing the weight distribution, and as a result, the amount of weight a truck can carry under those conditions.
How is load center calculated?
A load center is the horizontal distance from the vertical face of the forks to the center of gravity of the load. As a general rule, load center is 24″ from the face of the forks (the center point of standard 48” x 48” pallet).
What will happen if the combined center of gravity?
What will happen if the ” Combined Center of Gravity” moves outside the stability triangle? The lift truck will tip over in the same direction. As the load center increases the capacity increases. … Yes, the lift truck can safely lift the load.
What is forklift rated capacity?
Forklift capacity is the measurement of how much weight a particular forklift can lift.
Are fork extensions legal?
Are Forklift Boom Extensions Legal? Forklift boom extensions are legal, but they come with rules to prevent accidents. Fork extensions should not exceed 1.5 times the length of the forks.
