SAS - System of Active Stability
SAS is a Toyota developed system that uses sensors, actuators and a controller to provide higher levels of operability and stability to the forklift.
SAS monitors a number of key truck parameters, including fork load, speed, vehicle position and acceleration, and activates related measures to prevent mis-operation.
While the operator must always use care when turning a forklift, the SAS Active Control Rear Stabiliser will automatically lock the swinging of the rear axle to provide a high level of lateral stability for the forklift.
Even the most competent forklift truck operators are sometimes confronted with the loss of loads due to excessive movement of the mast. TOYOTA's SAS offers greatly improved mast control, enhancing the overall safety and stability of the truck. SAS has been made possible by TOYOTA's application of the latest developments in electronic control technology.
SAS Feature List
Active Control Rear Stabiliser Active Control Rear Stabiliser  An Occupational Health & Safety Agency survey of the forklift industry in the US highlighted that the two major types of accidents in which a forklift was involved where "tipping over" (25% of the cases) and "falling load" (14%).
Maintaining the stability of a turning forklift is therefore a critical, key safety objective.
Increased stability reduces the possiblity of a forklift tipping over and endangering the operator. To meet this goal TOYOTA has developed the unique "SAS Active Control Rear Stabiliser". SAS constantly monitors the stability of the forklift, through four separate sensors monitoring load height and weight, vehicle speed and turning rate.
If a potentially dangerous condition is detected, the system temporarily locks the swinging motion of the rear axle to provide the truck with a high level of lateral stability.
This greater truck stability in turn helps the operator concentrate on the job and reduces the stress associated with operating an unstable forklift.

The SAS: Active Mast Front Tilt Angle control prevents this situation. Special sensors on the mast tell the controller unit vital information on the height of the mast and the weight of the load, the controller unit calculates this information and limits the forward tilt angle of the mast thereby maintaining the trucks centre of gravity.

The SAS: Active Rear Tilt Speed Control resolves this problem and limits the speed at which a high and loaded mast tilts back. The mast sensors feed the relevant information to the controller unit, which then restricts the mast to an appropriate speed. This simply prevents loads from toppling over, as they would if the mast tilted back too fast. Click Here to View Movie
Active Steering Synchroniser Active Steering Synchroniser  All operators using full hydraulic power steering encounter steering wheel slippage. This means that the steering wheel knob doesn't always match the wheel position expected by the operator (caused by hydraulic slippage at full steering wheel lock).
In the past this problem has reduced operator productivity and safety by increasing the possiblity of the truck starting off in the wrong direction.
By applying the latest technology TOYOTA has ensured that the steering wheel is perfectly and constantly aligned with the rear wheels. The truck will now always start off in the direction expected by the operator, simultaneously increasing productivity and safety.

The SAS: Automatic Fork Leveling System addresses this problem. Whenever the mast is tilted backwards, bringing it back to a vertical position (forks horizontal) is simply achieved by pressing a switch at the top of the tilt actuator, whilst pushing the actuator forwards. Once the forks are horizontal, any further movement of the lever forwards is translated into .... no movement at all from the mast.

The SAS: Key-Lift Interlock feature prevents the forks from being lowered if the engine is not running. The risk of accidents resulting from an incorrect manoeuvre is thereby considerably reduced.
