Forklift Safety for a Better Tomorrow
No job can--or should--be completed without proper safety protocols in place. This is particularly true when dealing with heavy machinery, such as forklifts, in the workplace. The importance of operator safety training remains the first line of defense in reducing forklift-related incidents. However, it is known in the lift truck industry that errors in operator judgment often lead to accidents. Toyota has developed the world’s first System of Active Stability™ (SAS), derived from automotive technology. Toyota’s SAS and Active Mast Control (AMC) technologies were designed specifically to reduce the likelihood of accidents during these “errors in judgment” scenarios.
Still leading the industry in safety technology, no other lift truck brand offers a system comparable to Toyota’s SAS. With more than 250,000 SAS-equipped Toyota lift trucks in operation in North America and Toyota’s proven record of lift truck safety, you can feel confident knowing your operators are utilizing equipment that sets the industry standard in safety.
Toyota’s System of SAS electronically monitors and controls the lift truck’s operations to help reduce the risk of tip overs.
SAS is Composed of Two Systems: the Active Control Rear Stabilizer and the Active
Mast Function Controller.
Active Control Rear Stabilizer System
Toyota’s SAS uses patented technology to sense various factors that lead to potential lateral instability. When those conditions are detected, the SAS instantly locks a hydraulic cylinder on the rear steer axle, changing the lift truck’s stability footprint from triangular in shape to rectangular. The resulting increase in stability reduces the likelihood of a lateral overturn.
Active Mast Function Controller System
Similar in operation to the Active Control Rear Stabilizer, the Active Mast Function Controller System uses the same patented technology to sense various factors that lead to potential longitudinal instability. When the SAS controller senses potential longitudinal instability, two systems are activated to help reduce the chances of forward or rearward tip overs: forward tilt angle control and rear tilt speed control.
Forward Tilt Angle Control will sense load weight and mast height, then automatically override the operator’s manual control and limit forward tilt to decrease the chance of spilling a load or tipping the lift truck forward.
Rear Tilt Speed Control utilizes the same load and mast height sensors to govern the mast’s reverse tilt speed to half, thereby decreasing the chances of spilling unsecured loads or tipping the lift truck backward.
Safety Numbers Continue To Increase
More than 95,000 employees are injured every year while operating lift trucks in the United States.1 This has long been recognized as a serious problem, so Toyota created the world’s first System of Active Stability™ (SAS), derived from automotive technology. Following the introduction of SAS, transportation injuries involving forklifts in the United States have decreased while the SAS field population has increased between 1999 and 2010 (see below). While mandatory operator training enacted by OSHA certainly plays a large part in these reductions, the safety impact provided by SAS cannot be underestimated -Toyota’s SAS system helps reduce the likelihood of overturn incidents.
