What is the stability triangle of 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. If you imagine all three points connected into a triangle, this is the forklift’s stability triangle.

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 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.

What affects forklift stability?

The weight of the load on the forks. Positioning of the load. The weight of ballast (“counterbalance”) at the rear of the forklift. The surface of the floor (most forklifts are designed for level surfaces only)

What are the three points of the 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 the stability triangle used to describe?

The stability triangle is used to describe the movement of center of gravity of a load vehicle like trucks.

What factors can affect the forklift center of gravity and stability?

Determining a forklift’s safe load capacity

The load weight, weight distribution, size, shape, and position are key factors affecting the capacity and the stability of the forklift. Forklifts are designed to carry a capacity load at a standard load center, commonly 24 inches.

Where is the center of gravity for a loaded forklift?

A forklift has a fulcrum and two resistances, the counterweight on the back of the forklift and the load on the forks. The middle of the load is considered the load center when the load is evenly distributed across the pallet.

When picking up a load the forks should be?

Carrying the load

Keep the forks 6 to 10 inches above the ground to avoid potential hazards on the ground. Remember that forklifts are top-heavy. Carry the load low and tilted back. Use caution when carrying a load on an uneven surface; it creates a tip-over hazard.

When moving the forklift in reverse you must?

When should you drive a forklift in reverse?

  1. Always. Travel slowly when moving down slopes.
  2. Speed. Ensure the forks face uphill when traveling up or down slopes with a load because this ensures stability and prevents the load from falling off the fork arms. …
  3. Load. …
  4. No Load. …
  5. Never.

How do you ensure the load is stable?

Make sure the load is evenly balance across both forks. Make sure the heavier part of an unbalance object is towards the cockpit of the vehicle. Stack the load on the pallet or skid safely and correctly. Use securing measures such as ropes or bindings if required.

What will make the load more stable during travel?

When traveling with a load, always make sure to tilt the mast of the forklift backward so that the load will firmly place against the backrest to make it more secure during transport. By doing this, you move the center of gravity towards to rear of the forklift making it more secure when traveling.

What to do if forklift tips over?

If the forklift is tipping over, protect yourself by staying put:

  1. Stay in your seat and do not attempt to jump off.
  2. Lean away from the falling direction of the lift.
  3. Hold onto the steering wheel and make sure you’re stable.

How is forklift capacity calculated?

The maximum Load Moment for a truck is derived by multiplying the weight rating of the forklift by the center load distance. If we multiply the 5,000-pound capacity of our theoretical forklift by its 24-inch center load, we arrive at a maximum Load Moment of 120,000 inch-pounds.

How can a forklift be overturned?

How can a forklift be overturned? In a forklift overturn, the lift takes a turn that’s too sharp, or traveling too fast, and overturns. A tipover typically occurs when the maximum load capacity is exceeded, resulting in a tipover.
