HYDRAULIC DRIVING APPARATUS OF WORK MACHINE
Provided is a hydraulic driving apparatus capable of operating hydraulic actuators that actuate a boom, an arm, and a tip attachment at respective suitable speeds. The hydraulic driving apparatus includes a first hydraulic pump (11) connected to a first main actuator (6), a second hydraulic pump (12) connected to a second main actuator (7) and an attachment actuator (8), a first merging selector valve (13) that allows hydraulic fluid to be supplied from the first hydraulic pump (11) to the second main actuator (7), and a power distribution control device (60) that operates displacement of the first and second hydraulic pumps (11, 12) so as to decrease power distribution from a pump drive source (10) to the second hydraulic pump (12) and increase power distribution from the pump drive source (10) to the first hydraulic pump (11) when a specified combined operational action is performed on the second main actuator (7) and the attachment actuator (8).
