Where must a forklift’s center of gravity remain in order for the forklift to stay upright?

In order for the lift truck to be stable (not tip-over forward or to the side), the Center of Gravity must stay within the area of the lift truck stability base—a triangle drawn between the front wheels and the pivot of the rear axle.

Where is the center of gravity on a forklift?

The truck’s steer axle is attached to the truck by a pivot pin at the axle’s center. When the points are connected with imaginary lines, this three-point support forms a triangle called the stability triangle. When at rest, on level ground, the forklift’s center of gravity is within the stability triangle.

What is the combined center of gravity on a forklift?

Center of gravity is the point at which an object’s weight is evenly distributed and the object is balanced. The stability triangle is the area between the two front wheels and the middle of the rear axle. To stay upright, the forklift’s combined center of gravity must stay within the stability triangle.

What is the ideal location of the loads center of gravity when it is on the forks?

You should never turn the truck with the load raised. Keeping the center of gravity low, approximately four inches off the ground will help ensure a stable load. As you add weight to the forks, the center of gravity shifts closer to the front axle.

Where is the center of gravity located on an order picker?

When moving cargo, the center of gravity of the forklift should remain within the confines of the balance pyramid. If the center is outside this area, then the machinery is likely to tip over when moving.

What is the load center of a forklift?

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). Forklift capacities range from about 3,000 lbs up to more than 70,000+ lbs.

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 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.

When should you drive a forklift backwards?

If a load on the forks blocks your view of the intended path of travel, travel in reverse. Always maintain a safe distance from the forklift ahead of you (about three truck lengths)

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).

What can affect your lift truck center of gravity within the stability triangle?

Factors such as heavy and/or unbalanced loads, driving on sloping or uneven terrain, or turning with elevated loads can result in the center of gravity moving outside of the triangle.

When picking up a load the forks should be spaced?

Insert the fork all the way under the load (use forks that are at least two-thirds of the load length). Adjust the fork as wide as possible to fit the load and to provide a more even distribution of weight. Space the fork evenly from the centre stringer of the pallet to balance the load.

What happens to the combined Centre of gravity when you tilt the mast back?

As the mast is moved forward and back, the combined centre of gravity also moves forward and back. As the mast is tilted forward and back, the combined centre of gravity moves forward and back.

What is the most common load Centre distance?

24-inches is the most common load center, but 36-inch and 48-inch forklift load centers are also fairly common.

Which truck will resist tipping over sideways?

Forklifts have a “stability triangle”. A vertical line extending from the center of gravity of the vehicle and load combination must be inside of the stability triangle to prevent the forklift from tipping forward, falling sideways or dropping its load, as shown in the diagram below.

What is the center of gravity?

Centre of gravity, in physics, an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated. … When a drum is stood on end, its centre of gravity (CG) is firmly supported, and the drum is in stable equilibrium (A).
