System of Active Stability: What Exactly Does it Do?

Toyota’s System of Active Stability (SAS) detects unsafe situations using 14 sensors, taking over 3,000 reads per second.1 When SAS senses a dangerous situation, such as fast turns or towering mast height, it activates the appropriate safety feature.

One example of a safety feature is the active control rear stabilizer system. This system dectects lateral instability and uses a swing lock cylinder to lock the rear steer axle in place.1 This increases lateral stability and decreases the chances of tipping over sideways.

Another main feature is the Active Mast Control (AMC). AMC senses load weight and mast height, adjusting accordingly. Rear tilt speed control decreases the tilt speed. Similarly, forward tilt control overrides manual control, limiting the forward tilt of the mast. By limiting speed and tilt, AMC helps minimize the chance of dropping an unsecured load or tipping a forklift over forward or backward.

SAS is the first and only safety system of its kind in the forklift industry. It only requires a 30 second check every 250 hours of use and the safety it provides helps minimize accidents, saving money.1 Features like automated fork leveling, AMC, active control rear stabilizers and more makes SAS a valuable safety tool in any workplace.
