RELATIONSHIP BETWEEN LOAD CENTER AND STABILITY OF FORKLIFT TRUCKS

What is a Load Center?

The load center in forklift trucks is the distance measured from the face of the forks on the forklift to the load’s center of gravity on the forklift. This measurement indicates the optimal placement of the cargo to maintain the forklift’s balance during heavy lifting operations. A stable center of gravity is crucial for the safety and stability of the load during transport​​​​.

Forklifts are typically assigned vertical and horizontal load centers, often measured at 24, 36, or 48 inches, to help operators calculate the appropriate size and placement of the load. In the U.S., 24-inch load centers are commonly seen​​.

Importance of Stability and Load Centers

Adhering to the forklift’s load center is vital for safety. Proper load positioning prevents tipping and enhances operational efficiency. By balancing the load correctly, forklifts can operate safely, boosting productivity and reducing the risk of accidents​​​​.

Determining the Load Center of a Forklift

To find the load center:

  1. Check the Forklift Nameplate: It provides crucial data such as the distance from the load center, vertical mast height, tilt, and load height limitations.
  2. Even Load Distribution: The load center is typically at the midpoint for evenly distributed loads like pallets. For instance, a 1000 mm load would have a 500 mm load center.
  3. Limitations: Be mindful of the forklift’s load height and length limits. Loads exceeding the specified load center can be lifted only if significantly below the maximum weight limit.

Four Key Points for Safe Forklift Operation

  1. Stability Triangle: Forklifts use a three-point suspension system, forming a stability triangle. The combined center of gravity of the forklift and load should remain within this triangle to prevent tipping.
  2. Center of Gravity of the Load: Understanding the load’s center of gravity, mainly for non-uniform loads, is crucial. The forklift’s lifting capacity can decrease if the load center extends beyond the designated limit.
  3. Forklift Center of Gravity: As the load is lifted, the forklift’s center of gravity shifts forward. Ensuring it remains within the stability triangle is vital for preventing accidents.
  4. Safe Operation Environment: Maintain low and stable loads, drive carefully, and always use a seatbelt. Be extra cautious on slopes or uneven terrain to prevent the center of gravity from shifting outside the stability triangle.

When operating a forklift, in case of tipping, it is safer to stay inside the vehicle and brace oneself rather than attempting to jump out.
