A forklift truck can tip longitudinally, or forward, primarily due to an unbalanced load or improper operation. When the load is raised too high or is unevenly distributed, the center of gravity shifts beyond the wheelbase, leading to instability. Additionally, driving on inclines or making abrupt turns while carrying a heavy load can exacerbate this risk, causing the forklift to tip over. Proper load management and adherence to operational guidelines are essential to prevent such incidents.
Lift trucks (fork trucks, stackers, etc.) are rated for the maximum weight it can safely care at various heights of the forks (blades). The higher the forks the less stable the truck becomes, especially if trying to lift a heavy load, or turning too sharply at speed. The same goes for reach trucks, with or without side shift. So, if the load is too heavy, the rear of the truck will lift off the ground.

In the event of a lateral or longitudinal tip-over, the operator of a lift truck should remain in the operator's seat with the seatbelt fastened. They should brace themselves and avoid jumping from the truck, as doing so can lead to serious injury. The operator should also try to steer the truck away from hazards if possible, while keeping their body inside the protective confines of the vehicle. After the incident, they should report the tip-over and assess for any injuries or damages.
If a tip-over occurs, the operator of the lift truck should remain inside the vehicle, keeping their arms and legs inside the cab to avoid injury. They should brace themselves and lean away from the direction of the fall, if possible. Once the lift truck has settled, the operator should assess the situation and wait for emergency responders to help them exit safely. It's crucial not to jump out as this can lead to serious injuries.
The most common types of lift truck accidents include collisions with pedestrians or other vehicles, tip-overs due to uneven ground or excessive loads, and falls from elevated areas. Additionally, accidents can occur when operators fail to follow proper procedures or when equipment malfunctions.
In the event of a lateral lift truck tip-over, the operator should remain in the cab and hold onto the steering wheel to protect themselves from injury. They should avoid jumping out, as this can lead to serious injuries. Once the truck has come to a stop, the operator should assess the situation and wait for emergency assistance if needed. It's crucial to follow established safety protocols and training for such emergencies.

A narrow aisle lift truck, particularly a swing-reach or side-loader, is more prone to tipping over sideways when turning quickly due to its design and higher center of gravity. These trucks are built for maneuverability in tight spaces, which can compromise stability during sharp turns. Operators must exercise caution and adhere to safe turning practices to minimize the risk of tip-over incidents.
I do know this it was known in the beginning as a cherry picker than a man lift than a bucket truck for the bucket shaped man holder at the boom tip next in the early 1950's Telsta designed a T40 with wooden forks to hold the bucket in place it was the first aerial lift of it's kind
The narrowest part of the stability triangle of a lift truck is located at the rear axle, where the center of gravity (CG) must remain within the triangle formed by the front wheels and the rear axle. This area is critical for maintaining stability, as any shift in the load or elevation can cause the CG to move outside of this triangle, leading to a potential tip-over. Proper load management and awareness of the lift truck's capacity are essential to keep the CG within this stable zone.
The load in a full truck is mainly higher than the centre of gravity (COG) of the empty truck. As a result the COG of a full truck is higher. It is this than makes it easier to tip.
