Every year in Yukon, there are several hundred forklift accidents that are reported. Though operator training is certainly the most vital part of preventing workplace mishaps, it is not sufficient to reduce the number of incidences. Clearly, the best approach to preventing lift truck mishaps is having the organization and business involved, in addition to combining the efforts of everybody in the facility.
Toyota implements the SAS or System of Active Stability. This technology came from automotive technology. The SAS can electrically control and monitor lift truck operations. This particular system is important for helping reduce the risk of accidents from happening. When the SAS system detects any kind of instability, its advanced sensors signal simultaneously and engage the proper controller. The Active Mast Function Controller and the Active Control Rear Stabilizer help to prevent injuries or accidents occurring by adding stability.
Toyota's SAS system is a patented technology which is able to detect numerous factors that may result in possible lateral instability. If and when those conditions are detected, the SAS instantly 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 added stability. The result is an instant stability and really lessens the possibility of a lateral overturn from occurring.
When the machine detects instability occurring, the SAS engages instantly. Next, the rear axle becomes stabilized when the Swing Lock Cylinder is engaged. This creates the lateral stability the equipment needs to help reduce the chance of lateral tip-overs from happening.
Similar to the active rear stabilizer control, the active mast function controller utilizes the same technologies. Its function is to sense the many things which can lead to a potential longitudinal instability. When the SAS controller senses potential longitudinal instability from happening, 2 systems become engaged to help decrease the chances of forward and rearward tip-over situations from happening: the rear tilt speed control and the forward tilt angle 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 will also limit the forward tilt which will lessen the possibilities of forward tipping or spilling. These safety mechanisms are in place to help the operator be 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 greatly reduces the possibilities of having the forklift tilt backwards or spilling unsecured cargo.
