Each year in Canada, there are several hundred forklift mishaps that are reported. Though operator training is definitely the most essential part of preventing workplace mishaps, it is not enough to reduce the number of incidences. Obviously, the right method to avoiding forklift accidents is having the business and organization involved, in addition to combining the efforts of everybody in the facility.
Toyota has applied the SAS or System of Active Stability, that is technology derived from the automotive technology. The SAS is capable of electrically monitoring and controlling forklift operations. This system is really essential for helping reduce the possibility of mishaps from occurring. 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 avoid injuries or accidents happening by adding stability.
Toyota's SAS system is a patented technology which is able to detect numerous 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 situation happens, the stability footprint of the lift truck changes from triangular in shape to a rectangular shape, resulting in added stability. The outcome is an instant stability and greatly reduces the chance of a lateral overturn from occurring.
When the machine senses instability happening, the SAS engages immediately. After that, the Swing Lock Cylinder is engaged and the rear axle becomes stabilized. This creates the lateral stability the equipment needs to help reduce 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 numerous things that could result in a potential longitudinal instability. Whenever the SAS controller detects potential longitudinal instability from happening, 2 systems become engaged to help reduce the chances of forward and rearward tip-over situations from occurring: the rear tilt speed control and the forward tilt angle control.
The Forward Tilt Angle Control will sense load weight and mass height, then automatically override the operator's manual control and limit forward tilt to decrease the chance of tipping the forklift forward or spilling a load. All these safety mechanisms are in place to help the operator stay safe.
Utilizing the same mast height sensors and load sensors, the rear tilt speed control is designed to govern the mast's reverse tilt speed to half. This really reduces the chances of having the lift truck tilt backwards or spilling unsecured cargo.
