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)

On what principle is the stability of a lift truck based?

Forklift stability is based on keeping the center of gravity inside what’s called the stability triangle. This stability triangle is made by connecting the two front wheels and the pivot point of the rear axle. The other concept to understand is the forklift’s center of gravity.

What does stability triangle mean?

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 number one cause of lift truck accidents?

However, the statistics show that the greatest hazard is being crushed when the forklift tips over. According to OSHA in the United States, 70% of forklift accidents could have been avoided with standardized training and safety procedures.

What accidents could occur when a forklift truck is parked?

Gravity is one of the biggest dangers to forklift operators. Parking on a ramp, incline, or on an uneven surface can cause the forklift to roll on its own. If the surface is steep enough, the vehicle’s parking brakes may not be enough to stop it from rolling.

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 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.

  • Prohibit altogether the use of gasoline-powered tools or engines in enclosed areas.


When a lift truck is turning Is it more stable loaded or unloaded?

How should you raise the load? When a load is raised, the lift truck is less stable. … Attend the controls of the forklift truck when a load is elevated. In other words, the operator must stay on the forklift when the load is in a raised position.

Which is true for a counterbalance lift truck?

Q: Which is true for a counterbalance lift truck: “The higher the lift height… Its a tricky question, the higher the forks the more likely to tip over.

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).

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.)

When picking up a load it should be tilted?

Do not tilt a forklift forward with a load with the forks elevated except when a load must be picked up. When stacking a load, tilt the mast backward to stabilize it. When working with a maximum capacity load, tilt the mast backward and position the load, so the heaviest part is against the carriage.

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.
