Electrically-driven dump truck

An electrically-driven dump truck that involves the use of resistors to convert electric power generated during retarder braking operation into heat energy, the dump truck comprising:

• a body frame having front and rear wheels attached thereto;
• a support base mounted on an upper front section of the body frame;
• a cab mounted on an upper left surface of the support base;
• a control cabinet mounted on an upper surface of the support base such that the control cabinet is located on the right rear side of the cab;
• a base plate mounted on an upper surface of the support base, the upper surface being located to the right of the control cabinet;
• and
• a plurality of resistor boxes mounted on an upper surface of the base plate;
• wherein the plurality of resistor boxes are arranged on the upper surface of the base plate in a stacked manner such that the plurality of resistor boxes are located to the right of the control cabinet whereby a front vertical surface of the control cabinet and a front-facing side surface of the front stack of the resistor boxes are in the same plane along a width direction of the body frame in order to secure right side visibility from the cab, and
• wherein the plurality of resistor boxes each comprise:
• a substantially hexahedron-shaped casing having an inlet port at one end thereof and an outlet port at the other end thereof;
• resistors electrically connected in parallel, the resistors being housed in the casing;
• and
• a fan for cooling the resistors, the fan being housed in the casing.
