What should be closely monitored when the stacker fork lifts boxes?

Monitoring the center of gravity when the stacker fork lifts boxes is crucial for maintaining stability and safety during operation. The center of gravity refers to the point where the weight of the load is evenly distributed in all directions. If the load's center of gravity is too high or shifted, it can lead to tipping or loss of control of the forklift, especially when navigating turns or approaching obstacles.

When lifting boxes, ensuring that the center of gravity is within the stability triangle of the forklift helps to prevent accidents and ensures that the load does not become unstable. It's essential to position the load correctly on the forks to align the center of gravity safely, as even a small misalignment can significantly affect the forklift's ability to operate safely.

Monitoring other factors, such as load weight, speed of lift, and fork height, while also important, may not address the immediate risk of tipping that comes from an improperly balanced load. The center of gravity directly influences the forklift's stability and operational safety, making it a vital aspect to keep in check during lifting operations.
