T/CCMA 0034-2015 Durability Test for Rotary Motors Used in Hydraulic Excavators in Laboratories
T/CCMA 0034-2015
Basic Information
Scope
Scope: This standard specifies the technical requirements, test methods, and inspection rules for the durability test of rotary motors used in hydraulic excavators (hereinafter referred to as hydraulic motors) in the laboratory. This standard applies to the durability test of rotary motors used in medium-sized (20 t~23 t) hydraulic excavators with a system working pressure of ≤35 MPa. The hydraulic motors involved in this standard are fixed-displacement, with relief valves, buffer valves, anti-reverse valves, and brakes, and are bidirectional rotating axial piston motors.
