What can cause the forklift to tip over sideways?

Turning with a load in the air can significantly increase the risk of a forklift tipping over sideways due to the combined effects of the forklift's center of gravity and the load's weight. When a forklift is turning, particularly with a high load, the center of gravity shifts, and if the load is elevated, it raises the center of gravity even further. This imbalance can lead to a higher likelihood of tipping, especially if the turn is sharp or the surface is uneven.

In contrast, driving in reverse, while potentially increasing the risk of other hazards, does not inherently cause a sideways tip unless done under certain conditions, such as with an elevated load or on an incline. Raising the forks too high can create instability but typically affects tipping forward rather than sideways. Driving on a flat surface is the safest condition for maintaining stability, making it unlikely to contribute to a sideways tip-over.
