PURPOSE: An axle locking control device of an excavator is provided to promote the convenience on works by controlling the movement of an excavator, the rotation of a boom and the inclination of a boom simultaneously. CONSTITUTION: The axle locking control device of an excavator contains a hydraulic pump generating hydraulic pressure, a solenoid valve(13) controlling an inflow of hydraulic pressure generated from the hydraulic pump, a ram cylinder(14) buffering the shake of an axle of an excavator using hydraulic pressure when opening the solenoid valve(13), and ram switches(20,30) switching on/off the power of the solenoid valve(13). The ram switches(20,30) contain a primary switch(20) controlled by hands and a secondary switch(30) controlled by feet.
