Abstract
This work machine includes: a telescoping actuator that moves a first boom in the telescoping direction with respect to a second boom; an electrical drive source that is disposed in a movable portion of the telescoping actuator; a first connection mechanism that switches a connection state between the telescoping actuator and the first boom on the basis of the power of the electrical drive source; a second connection mechanism that switches a connection state between the first boom and the second boom on the basis of the power of the electrical drive source; and a control device that controls operation of the electrical drive source. The control device executes motor assist processing of operating the electrical drive source when the first fixing pin and/or the second fixing pin is restored by biasing force.
