When does longitudinal tip over of the forklift occur?

Longitudinal tip-over of a forklift occurs when the center of gravity shifts too far forward or backward, causing the forklift to overturn in the direction of the shift. This can happen during actions such as lifting loads that are too heavy, driving on inclined surfaces, or braking suddenly while carrying a load. Maintaining a proper load balance and adhering to safety guidelines can help prevent this type of accident.
