Preventing A Tipped Forklift
Forklift tip-overs not only result in damage to the truck itself but can also cause serious injuries or fatalities to the operator. Tipping is a cause of unsafe practices in which the forklift becomes unbalanced and tips over. In order to avoid tipping, the stability of a forklift must always be maintained. If the mass is centered, the truck is less likely to tip and cause damage to the truck and operator. A forklift can tip over at any time, but fortunately preventing a tipped forklift can be avoided by following safe operating procedures.

Pay attention to the load capacity and do not exceed it
Overloading a forklift causes the center of gravity to be thrown off, causing it to become unstable and tip-over. This information can be found on the data plate located on the forklift. With this, the forks must be loaded and centered properly to avoid imbalance.
Tilt the load backwards when travelling
This simple procedure helps stabilize the forklift. A forward tilting mast - especially carrying a load can result in a forward tip.
Drive with your forks low - a forklift should not be in motion with a raised load
Forks should not be more than four inches off the ground while the forklift is in motion. Travel with forks low, at a slow speed, then stop the truck and raise the forks once you're at your destination.
Drive your forklift at a slow speed & don't brake suddenly
Suddenly speeding up or braking too quickly can cause the center of gravity to shift and result in the forklift becoming unstable and tipping over. Whether you're travelling forward or backwards, aggressive braking can result in tip-overs.
Watch for Hazards
Avoiding obstacles, like potholes, can cause the forklift to become unbalanced and tip over. Other hazards that may seem obvious include pedestrians, wet/oily/icy ground, and debris.
