According to OSHA, “The load center is the distance from the face of the forks to the load’s center of gravity.” It is important for operators and managers to understand the forklift load’s center of gravity in order to operate and transport loads safely in their operations.
When a forklift is loaded where is its center of gravity?
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 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.
How do you calculate 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.
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.
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)
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.
Where can I not park a forklift?
Do not park an industrial lift truck near doorways, switches and electricity boards, fire fighting equipment, blind corners, on inclines, on soft ground, middle of an aisle, fire exits or pedestrian walk ways.
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.
How is forklift load chart calculated?
A couple of simple calculations are all that’s necessary:
- Divide the load center as stated on the data plate by the actual load center (in the example above, that would be 24/36=. 6666).
- Multiply this result by the rated load capacity (4000X. 6666=2666.6).
How is load center calculated?
The standard load center is 24″ out from the forks’ vertical face. Let’s say we want to know how much weight we can carry with a load center of 30″. We divide 24″ (standard load center) by 30″ (actual load center) and then multiply it by the standard rated capacity of the forklift (let’s say 6,000 lbs.).
What is the load capacity?
Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifications. This maximum force includes static (mass × gravity) and dynamic forces (mass × acceleration).
How do you determine the weight of a load?
Calculating the Weight of a Load
- Step 1: Determine the Volume of the Load. Rectangle/Square: Volume = Length x Width x Height. …
- Step 2: Determine the Material You’ll Be Lifting. The table below can be used for approximate weight values of common loads and materials: …
- Step 3: Determine the Weight of Object.
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.
What should you not do when a load is elevated?
Never raise a load or turn on an uneven surface. In such cases, your center of gravity will quickly move outside of the stability triangle. While traveling empty on a ramp, your forks should always point downhill.
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).
