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.
What are the three points of a forklift that make up the stability triangle?
There’s the weight of the load itself and the counterbalance weight located in the engine. This weight is distributed on three points—the front two wheels and the pivot point on the back axel—forming an imaginary “triangle.” This is the stability triangle of the forklift.
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. This is sometimes referred to as the “stability triangle”.
What is the ideal location of the load’s center of gravity when it is on the forks?
Load Center: The horizontal distance from the vertical face of the forks to the center of the gravity load. As a general rule, the load center is 24-inches from the face of the forks or the center point of a 48-inch by 48-inch pallet.
What is the center of gravity for a forklift?
An unloaded forklift’s center of gravity is between the axle of the steer wheels at A and the drive wheels at B-C. When the forklift is unloaded, the location of the center of gravity is the only factor for determining stability.
Where is the fulcrum point on a narrow aisle forklift?
On a sit-down counterbalanced forklift, the fulcrum or pivot point is the axle of the front wheels. It is this product, or Load Moment, which determines how much overturning force is being applied to the forklift.
What information is found on a forklift load plate?
The data in the table specifies important information regarding the forklifts load handling capabilities: Load Height is the maximum height the forklift mast can lift a load. Maximum Capacity Mast Vertical is the maximum weight the forklift can lift when the mast is extended to its full height.
What should you do if a forklift truck begins to tip over?
If the forklift is tipping over, protect yourself by staying put:
- Stay in your seat and do not attempt to jump off.
- Lean away from the falling direction of the lift.
- Hold onto the steering wheel and make sure you’re stable.
Where is the pivot point on a forklift?
On a sit-down counterbalanced forklift, the fulcrum or pivot point is the axle of the front wheels.
What causes a forklift to tip over?
A longitudinal or forward forklift tip-over happens when the center of gravity moves too far forward. That’s more likely to occur when a lift is driven down a slope or ramp.
What formula determines the load’s moment?
A load moment is when a load center’s distance from a fulcrum increase. This determines how much overturning force is being applied to the forklift, and is a product of load weight times distance from the fulcrum (i.e., load moment = weight x distance).
Where is the load center located on 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.
When traveling up or down an incline on a forklift?
When traveling with a load, the load should point up the incline, regardless of direction of travel. Going up the incline: Drive forward. Forks pointed upgrade.
What is the effect on forklift by placing the fulcrum closer to the load?
Since the weight of the load is positioned closer to the fulcrum, more force is required to move it than the rear counterweight. This difference allows the rear counterweight to offset the added weight of a load (i.e., counterbalance it) and ensure the unit’s stability.
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.
What makes a forklift counterbalanced?
Designed with Forks out Front: Counterbalance forklifts are designed with their forks protruding out at the front of the vehicle, and they don’t have any outrigging legs or arms to stabilize them. This means that you can drive your forklift right up the the precise spots where your load or racking is located.
