Product Code:SAE J1177
Title:Hydraulic Excavator Operator Controls
Issuing Committee:Mtc C5, Excavators
Scope:This SAE Recommended Practice is intended as a guide for designing uniform two lever type operating controls for mobile hydraulic excavators, either wheel mounted or crawler mounted on independently reversible tracks. It is not intended to limit new design innovation or to force a change on existing machines. This recommended practice covers mobile hydraulic excavator controls and the specific arrangement and direction of motion for the primary controls. This recommended practice applies to mobile hydraulic excavators. (A mobile hydraulic excavator is defined as a self-propelled machine with an upperstructure capable of continuous rotation and which digs, elevates, swings, and dumps material by action of the boom and arm or telescoping boom with bucket.)
