Several hundred forklift accidents are sadly reported in Canada each year. Operator training is not sufficient to reduce the number of incidents, suffice to say, although, it is certainly one of the most important parts. Obviously, the right method to preventing lift truck mishaps is having the organization and company involved, in addition to combining the efforts of everyone in the facility.
Toyota applies the SAS or System of Active Stability. This technology came from automotive technology. The SAS could electrically control and monitor forklift operations. This system is important for helping reduce the possibility of accidents from happening. 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 avoid injuries or accidents happening by adding stability.
The patented technology provided by Toyota's SAS system is in place to detect many things which lead to possible 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 forklift changes from triangular in shape to a rectangular shape, resulting in more stability. The result is an immediate stability and greatly reduces the chance of a lateral overturn from happening.
When the machine detects instability occurring, the SAS engages immediately. Next, the Swing Lock Cylinder is engaged and the rear axle becomes stabilized. This creates the lateral stability the machinery requires to help lessen the chance of lateral tip-overs from happening.
The active mast function operates like the active rear stabilizer control. The active mast function controller system utilizes the same patented technology to detect many things which lead to potential longitudinal instability. When the SAS controller senses potential longitudinal instability from happening, 2 systems become engaged to help lessen the possibilities of rearward and forward tip-over accidents from occurring: the rear tilt speed control and the forward tilt angle control.
The Forward Tilt Angle Control will detect mast height and load weight, then automatically override the operator's manual control and limit forward tilt to lessen the possibility of tipping the lift truck forward or spilling a load. These safety devices are in place to help the operator be safe.
Utilizing 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 really decreases the possibilities of having the forklift tilt backwards or spilling unsecured loads.
