SAE controls

SAE controls are a standard that specifies how a human operator controls the digging components (i.e. swing, boom, stick, 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 stick.

Controls

In the SAE control pattern, the left hand joystick controls Swing (left & right) and the Stick (in & out), and the right hand joystick controls the Boom (up-down) and Bucket motions (close & dump).

• Left hand left = Swing left.
• Left hand right = Swing right.
• Left hand forward = Stick out.
• Left hand back = Stick in.

• Right hand left = Bucket close.
• Right hand right = Bucket dump.
• Right hand forward = Boom lower.
• Right hand back = Boom raise.

Usually, excavators comes with that kind of settings (SAE) from all manufacturers (Komatsu, Caterpillar, Kobelco, Hyundai, Doosan, Hitachi, Link Belt, Kubota). Some excavators have the possibility with the easy motion of a single switch, to change the operating mode from SAE to ISO and, from ISO to SAE.
