Load weight, weight distribution, size, shape, and position are key factors affecting the stability of the forklift. Forklifts are designed to carry a capacity load at a standard load center, commonly 24 inches.
What dictates the center of gravity of a loaded forklift?
The heavier the load – and the higher you lift – the further forward the combined center of gravity goes.
How does increasing the load Centre affect the capacity of a forklift truck?
Rated capacity forklift
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.
Which of the following will occur if the combined center of gravity for a forklift moves outside?
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 factors make forklifts more likely than cars to tip over?
FOUR CAUSES OF FORWARD FORKLIFT TIP OVERS
- Carrying Loads Heavier Than Recommended Load Ratings. …
- Carrying a load with the mast tilting forward. …
- Accelerating or braking too quickly. …
- Lifting or lowering a load on a slope.
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 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).
How is forklift capacity 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.
What are 3 methods of determining the weight of a load?
Simple Methods to Determine the Weight of a Load
- Look at the Load to See if the Weight is Marked. …
- Load Familiarity. …
- Refer to Engineered Prints or Design Plans. …
- Review Bill of Lading or Shipping Documentation. …
- Use an Industrial Scale. …
- Refer to the Manufacturer’s Specifications or Catalog Data.

Are you allowed to turn a forklift on a ramp or slope?
Generally, a forklift can safely travel on a ramp with a gradient between 5% and 12.5%. But, it is always best to err on the side of caution. If a ramp looks too steep, forklift operators should avoid it.
What is the best way to handle an uneven load?
Tilt the load against the backrest. If the load is unstable, lift the load slightly first, then carefully tilt it back so that the load stays tight against the backrest. If it’s a stable load and secure on the pallet, tilt first, then lift. Once the load is lifted, lower it to a safe traveling height.
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).
When driving on a slope you should keep the back of a loaded forklift pointed uphill?
Stay at least three vehicle lengths behind the vehicle ahead of you. When driving on an incline with a load, always travel with the load pointing uphill. When driving on an incline with no load, always travel with the forks pointing downhill.
Why do Forklifts tip so easily?
Here are examples situations that can cause a forklift to tip over: The center of gravity is on the side of the stability triangle. This might be caused by turning a corner, having an unbalanced load, driving into a pothole, or traveling on a sloping surface. … The forklift quickly accelerating in reverse, or.
Where can you not park a forklift?
Do not park the forklift in a location with its fork arms protruding the passageway, where there are a lot of pedestrians who will have to step over them. Do not leave the truck in any access doorways and it should not block any stairways of the workplace. Never leave the truck near first aid stations.
Why do forklifts have rear steering?
Rear wheel steering allows very sharp turns and high precision maneuvering in the tight spaces where fork lifts are often used. This is the primary reason. … The other reason is that the front wheels carry the heaviest load, and provide the traction that allows the forklift to be driven.
