SAE controls are a standard that specifies how a human operator controls the digging components (i.e. swing, boom, dipper, bucket) of a piece of heavy machinery, such as a backhoe or excavator.
SAE controls are one of the two most common control patterns in the United States. The other most commonly used control pattern is ISO controls, which differs from the SAE control pattern only in that ISO controls exchange the hands that control the boom and the dipper.
Famous quotes containing the words sae and/or controls:
“Had we never lov’d sae kindly,
Had we never lov’d sae blindly,
Never met—or never parted,
We had ne’er been broken hearted.”
—Robert Burns (1759–1796)
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
