摘要： PROBLEM TO BE SOLVED: To provide a working machine with a lifting magnet which is capable of attracting a magnet even when the engine speed is not higher than a predetermined value, and high in attraction power. SOLUTION: In the working machine with the lifting magnet, when the engine speed is set to be not higher than a predetermined value by an engine speed control means, a signal is given from a body controller 9 to a regulator 9A of a hydraulic pump 6 so that the displacement volume of the hydraulic pump 6 is increased, and the number of rotation of a hydraulic motor 8 is increased by increasing the discharge amount of the hydraulic pump 6. The range of the engine speed is extended so that the magnet voltage to be output from a generator 10 can be maintained at the voltage not lower than the predetermined value at which the lifting magnet 13 can be attracted even in a predetermined range in which the engine speed is lower than a predetermined value.
