Focused on Safety
Each year, more than 94,000 lift truck accidents are reported in the United States. Suffice to say, operator training isn't enough to reduce the number of incidents, however, it is the most important component. Naturally the best approach to preventing lift truck accidents is one that combines the efforts of every person, business and organization involved.
As for lift truck manufacturers, Toyota decided to take the lead role. The result was creating the world's first System of Active Stability™(SAS).
Derived from automotive technology, SAS is able to electronically monitor and control lift truck operations, helping to reduce the risk of accidents. In short, when the SAS system detects instability, its advanced sensors simultaneously signal and engage the appropriate controller. The Active Control Rear Stabilizer or the Active Mast Function Controller adds stability and helps avoid accidents or injuries.
Active Control Rear Stabilizer System
Toyota’s SAS uses patented technology to sense various factors that lead to potential lateral instability. When those conditions are detected, the SAS instantly locks a hydraulic cylinder on the rear steer axle, changing the lift truck’s stability footprint from triangular in shape to rectangular. The resulting increase in stability reduces the likelihood of a lateral overturn.
When it senses instability, SAS instantly engages the Swing Lock Cylinder to stabilize the rear axle, creating the lateral stability needed to help reduce the risk of lateral tipovers.
Active Mast Function Controller System
Similar in operation to the active rear stabilizer control, the active mast function controller system uses the same patented technology to sense various factors that lead to potential longitudinal instability. When the SAS controller senses potential longitudinal instability, two systems are activated to help reduce the chances of forward or rearward tipovers: forward tilt angle control and rear tilt speed control.
Forward Tilt Angle Control will sense load weight and mast height, then automatically override the operator’s manual control and limit forward tilt to decrease the chance of spilling a load or tipping the lift truck forward.
Rear Tilt Speed Control utilizes the same load and mast height sensors to govern the mast’s reverse tilt speed to half, thereby decreasing the chances of spilling unsecured loads or tipping the lift truck backward.
