Each year in Canada, there are a few hundred forklift accidents that are reported. Although operator training is definitely the most vital part of preventing workplace mishaps, it is not enough to reduce the number of incidences. Clearly, the right method to preventing forklift mishaps is having the organization and business involved, as well as combining the efforts of every individual in the facility.
Toyota has implemented the System of Active Stability or SAS, that is technology derived from the automotive technology. The SAS can electrically control and monitor lift truck operations. This system is essential for helping lessen the possibility of accidents from happening. Whenever the SAS system senses any type of instability, its advanced sensors signal simultaneously and engage the proper controller. The Active Control Rear Stabilizer and the Active Mast Function Controller help to avoid accidents or injuries occurring by adding stability.
The patented technology offered by Toyota's SAS system is in place to sense many factors which result in potential lateral instability. If and when those conditions are detected, the SAS immediately locks a hydraulic cylinder on the rear steer axle. If this situation happens, the stability footprint of the lift truck changes from triangular in shape to a rectangular shape, resulting in an increase in stability. The outcome is an immediate stability and really lessens the chance of a lateral overturn from happening.
The SAS system engages instantly, when the machine senses the occurrence of instability. After that, the rear axle becomes stabilized when the Swing Lock Cylinder is engaged. This creates the lateral stability the machinery needs to help lessen the possibility of lateral tip-overs from happening.
Like the active rear stabilizer control, the active mast function controller utilizes the same technologies. Its function is to sense the many things which may result in a possible longitudinal instability. When the SAS controller senses potential longitudinal instability from occurring, 2 systems become engaged to help lessen the possibilities of rearward and forward tip-over situations from occurring: the forward tilt angle control and the rear tilt speed control.
The machinery forward tilt angle control could detect the load weight and mast height, the will override the operator's manual control automatically. It would also limit the forward tilt which would decrease the chances of forward tipping or spilling. All these safety mechanisms are in place to help the operator stay safe.
The Rear Tilt Speed Control uses the same mast height sensors and same load sensors to govern the mast's reverse tilt speed to half. This really reduces the possibilities of having the forklift tilt backwards or spilling unsecured cargo.
