PROBLEM TO BE SOLVED: To provide a revolution control device capable of reducing the power loss of a hydraulic pump during reverse operation, and to provide a construction machine equipped therewith.SOLUTION: During forward operation when an operating direction detected by operation sensors 18A, 18B corresponds to a revolving direction detected by a rotation sensor 23, a controller 24 sets the capacity of a hydraulic pump 15 to be larger as a control input detected by the operation sensors 18A, 18B is greater, while during reverse operation when the operating direction detected by the operation sensors 18A, 18B is opposite to the revolving direction detected by the rotation sensor 23, it further restricts the capacity of the hydraulic pump 15 than during the forward operation. |
