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 fulcrum, or pivot point, is the dividing line between the machine’s weight and the load’s weight.
Where is the fulcrum or forward point of balance of a forklift?
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.
Where is the stability triangle on a forklift?
A forklift has a three-point suspension system. The points are found over both of the two load (front) wheels and midway between the rear wheels. When imaginary lines are drawn to connect them, what’s known as the stability triangle is formed.
Where is the pivot point for a stand up forklift?
The stability of a sit-down rider type forklift is based on the “Principle of Balance”. The balance or pivot points of the truck are the Drive Wheels.
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?
Can a Forklift Tip-Over Without a Load? A forklift can become unstable, even if it does not have a load. For example, if a driver turns too fast around a sharp curve, their lift can tip. Or, if a driver is traveling on an unbalanced surface, their lift can tip if it shifts too far in one direction.
What three points make up a forklift’s stability triangle?
The three points are the two front wheels and the pivot point of the rear axle. Connect the three points, and you have what’s called the stability triangle.
What is a stability triangle on a forklift?
What is the stability triangle? Most counterbalanced forklifts have a three-point suspension system, meaning that the truck is supported at the two front wheels and the center of the steer axle. … When the lift truck’s center of gravity falls within the perimeter of this triangle, a load is safe to carry.
What is the first side of the stability triangle?
The “stability” triangle is an imaginary triangle with three sides; the first side is the: front axle and the other two sides are made up by drawing a line from each front tire to the middle of the back axle, where the main load support is located. gravity and stability? (Select all that apply.)
What gives added stability to the load when traveling?
Drive under the load until it touches the carriage. Tilt the forks back to shift the weight of the load and make it more stable. If the load is unbalanced, keep the heavier end closer to you.
What is the number one cause of forklift accidents?
Forklift overturns are the leading cause of fatalities involving lift trucks. Overturns can be caused by: Improper turning. Driving with an elevated load.
Which side of the forklift is supporting more weight?
Weight distribution refers not only to the weight of the load, but also the weight of the forklift itself. An empty forklift has most of its weight in the rear, but when a load is placed on the lift, the weight distribution moves forward.
When picking up a load the forks should be spaced?
The forks should be at least two-thirds the length of the load. The mast must be carefully tilted backward to stabilize the load. Ensure the load is secured before moving. Slowly move the truck to 20 to 30 cm (8 to 12 inches) away from the stack.
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 SWL of forklift calculated?
It is easily calculated by measuring the load to be carried, and dividing by two (providing the load is evenly distributed, and positioned to butt up to the forklift backrest). You will often see a forklift truck’s nominal capacity quoted in a form such as 2,000kg @ 500mm load center.
What happens when the load center on the forklift increases?
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.
