Abstract
In a regenerative braking device of a dump truck comprising an engine, a first generator and a second generator driven by the engine, at least one travel motor driven by generated electric power of the first generator and at least one fan motor to which generated electric power of the second generator is inputted via a first rectifier circuit, the regenerative braking device comprises: a resistive element to which regenerating electric power from the at least one travel motor in regenerative braking is supplied and which is cooled by at least one fan driven by the at least one fan motor and converts electric energy into heat energy and dissipates heat; and a DC/DC converter that inputs a part of the regenerating electric power which is supplied to the resistive element to an output line of the first rectifier circuit via a second rectifier circuit.
