A few hundred forklift mishaps are sadly reported in Canada every year. Operator training is not sufficient to lessen the number of incidents, suffice to say, although, it is definitely among the most important components. Clearly, the right approach to preventing lift truck accidents is having the company and organization involved, as well as combining the efforts of everybody in the facility.
Toyota applies the System of Active Stability or SAS. This technology originated from automotive technology. The SAS can electrically control and monitor forklift operations. This system is important for helping lessen the risk of mishaps from happening. When the SAS system detects any type of instability, its advanced sensors signal simultaneously and engage the correct controller. Both the Active Control Rear Stabilizer and the Active Mast Function Controller help to prevent injuries or accidents occurring by adding stability.
Toyota's SAS system is a patented technology that can detect many factors that can lead to potential lateral instability. If and when those conditions are detected, the SAS instantly locks a hydraulic cylinder on the rear steer axle. If this specific situation occurs, the lift truck's stability footprint changes from triangular in shape to a rectangular shape, resulting in an increase in stability. The outcome is an immediate stability and greatly reduces the likelihood of a lateral overturn from occurring.
The SAS system engages instantly, when the machine detects the occurrence of instability. After that, the Swing Lock Cylinder is engaged and the rear axle becomes stabilized. This creates the lateral stability the machinery needs to help decrease the chance of lateral tip-overs from happening.
The active mast function operates like the active rear stabilizer control. The active mast function controller system utilizes the same patented technology to sense many factors which lead to potential longitudinal instability. When the SAS controller detects potential longitudinal instability from happening, 2 systems become engaged to help lessen the possibilities of rearward and forward tip-over situations from happening: the forward tilt angle control and the rear tilt speed control.
The Forward Tilt Angle Control will detect mast height and load weight, then automatically override the operator's manual control and limit forward tilt to reduce the possibility of tipping the forklift forward or spilling a load. All these safety devices are in place to help the operator be safe.
The Rear Tilt Speed Control uses the same load sensors and same mast height sensors to govern the mast's reverse tilt speed to half. This greatly decreases the possibilities of spilling unsecured loads or having the forklift tilt backwards.
