Each year in North Dakota, there are a few hundred forklift mishaps which are reported. Though operator training is definitely the most important part of avoiding workplace accidents, it is not enough to reduce the number of incidences. Clearly, the best method to preventing lift truck mishaps is having the business and organization involved, as well as combining the efforts of everyone in the facility.
Toyota applies the SAS or System of Active Stability. This technology originated from automotive technology. The SAS could electrically control and monitor forklift operations. This system is important for helping reduce the chance of mishaps from occurring. Whenever 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 happening by adding stability.
The patented technology offered by Toyota's SAS system is in place to detect many factors which cause 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 to a rectangular in shape from a triangular in shape, resulting in added stability. The result is an instant stability and really reduces the possibility of a lateral overturn from happening.
When the machinery senses instability happening, the SAS engages immediately. Then, the Swing Lock Cylinder is engaged and the rear axle becomes stabilized. This creates the lateral stability the machine needs to help reduce the possibility of lateral tip-overs from happening.
Like the active rear stabilizer control, the active mast function controller uses the same technologies. Its function is to sense the numerous things which could result in a possible longitudinal instability. Whenever the SAS controller detects possible longitudinal instability from happening, 2 systems become engaged to help reduce the chances of rearward and forward tip-over situations from happening: the forward tilt angle control and the rear tilt speed control.
The machines forward tilt angle control is able to sense the mast height and load weight, the will override the operator's manual control automatically. It would also limit the forward tilt which would lessen the possibilities of spilling or forward tipping. These safety devices are in place to help the operator stay safe.
Using the same load sensors and mast height sensors, the rear tilt speed control is designed to govern the mast's reverse tilt speed to half. This greatly decreases the chances of having the forklift tilt backwards or spilling unsecured cargo.
