This standard specifies the technical requirements, test methods and inspection rules for laboratory durability testing of swing motors for hydraulic excavators (hereinafter referred to as hydraulic motors). This standard is applicable to the laboratory durability test of swing motors (hereinafter referred to as hydraulic motors) for medium-sized (20t ~ 23t) hydraulic excavators with system working pressure ≤35MPa. The hydraulic motors covered by this standard are fixed-displacement, bi-directional rotating axial piston motors with relief valves, buffer valves, anti-reverse valves and brakes.
