<p>PROBLEM TO BE SOLVED: To provide a work machine hydraulic pump capacity control device which can improve an operation feeling by minimizing a variation in a drive speed of a work device when a user performs operation to drive the work device.SOLUTION: When an operation input section 25a receives input for operation of a winch motor 24b without the input for the operation of a boom, a work machine hydraulic pump capacity control device adjusts discharge capacity of a second hydraulic pump 32 only on the basis of a calculated load factor while maintaining the discharge capacity of a first hydraulic pump 31. Thus, when increasing a drive speed of the winch motor 24b by merging hydraulic oil discharged from the first hydraulic pump 31 with the hydraulic oil discharged from the second hydraulic pump 32, the work machine hydraulic pump capacity control device prevents the drive speed of the winch motor 24b from being decreased in association with a temporal reduction in the discharge capacity of the first hydraulic pump 31.</p> |
