What happens if the center of gravity moves outside of the stability triangle while operating a forklift?

1. The load will become lighter

2. The forklift may tip over

3. The engine will stall

4. The forks will malfunction

The correct answer is: The forklift may tip over

When the center of gravity moves outside of the stability triangle while operating a forklift, it can lead to a dangerous situation where the forklift is at risk of tipping over. The stability triangle is a concept that refers to the triangular area formed by the contact points of the forklift's tires on the ground. This triangle is critical for maintaining balance and stability. When the load is raised or shifted in a manner that causes the center of gravity to extend beyond this triangle, the forklift can no longer maintain its balance, leading to a potential overturning incident. This scenario is particularly hazardous when the load is heavy or not properly secured, as it exacerbates the shift in the center of gravity. Understanding the dynamics of weight distribution and the importance of keeping the load within the stability triangle is essential for safe forklift operation. This knowledge is vital for operators to prevent accidents and ensure a safe working environment.
