The stability triangle is one of the most fundamental safety concepts for counterbalance forklift operation, which directly relates to the risk of side or forward rollover in daily warehouse and logistics scenarios. Most new operators may not fully understand the working logic behind this simple rule, even many experienced operators may overlook its constraints when handling urgent tasks.

The stability triangle is formed by three fixed supporting points of the forklift. Two of the points are located at the center of the two ends of the front drive axle, and the third point is located at the lowest contact position of the rear counterweight with the virtual supporting plane. The area enclosed by these three points is the safe stability range for the entire forklift. As long as the combined center of gravity of the forklift body and the loaded cargo stays strictly inside this triangle, the forklift will keep a stable standing state without tipping over. Once the combined center of gravity moves beyond any edge of the triangle, the forklift will lose balance and face rollover risk.

Many irregular operations will push the combined center of gravity out of the stability triangle. For example, traveling at high speed with cargo lifted to a very high height will move the center of gravity upward and forward, making it easy to cross the front edge of the triangle when braking suddenly. Sharp turning at high speed will generate large centrifugal force, pulling the combined center of gravity to the side and cross the side edge of the triangle. Overloading cargo far beyond the rated load limit, or placing the load far away from the fork root, will also push the center of gravity out of the safe range.

As a professional supplier focusing on BYD electric forklifts, we are Jian Shu New Energy. We attach great importance to popularizing forklift safety knowledge for all our users, and clearly inform every operator that the reasonable counterweight design of qualified electric forklifts can provide a more reliable and stable stability triangle under rated working conditions. We suggest all operators form good operation habits: keep the forks at 10 to 15 cm above the ground when traveling, slow down in advance before turning, avoid turning or adjusting cargo position on slopes, do not exceed the rated load limit at any time.
