CONTROLLER FOR HYDRAULIC PUMP HORSEPOWER AND WORK MACHINE PROVIDED THEREWITH
A controller (5) includes: a storage unit (31) that stores a map in which an operation amount and an upper limit value of suction horsepower of a hydraulic pump (17A,17B) are associated with each other, for each operation content identified by a cylinder (9,11) that is an operation object out of the cylinders (9,11), and by a direction of operation performed on this cylinder (9,11); an operation horsepower determination unit (32) that determines the upper limit value of suction horsepower for each cylinder (9,11) by using the map stored in the storage unit when an actuation command relating to at least one cylinder is input by an operation lever; a high-level selection unit (33) that selects the maximum upper limit value of suction horsepower out of the upper limit values of suction horsepower determined by the operation horsepower determination unit; and a regulator (24A,24B) that regulates a displacement of the hydraulic pump so as to obtain horsepower equal to or lower than the suction horsepower selected by the high-level selection unit (33).
