PROBLEM TO BE SOLVED: To provide an electric traveling vehicle which prevents a malfunction that a parking brake cannot be released, thereby mobile work with the electric traveling vehicle cannot be carried out.SOLUTION: An electric traveling vehicle is equipped with: a parking brake device which applies parking brake force to a brake disc according to a parking brake command and releases the parking brake force by brake release pressure by hydraulic pressure; and a brake release device which has an accumulator and supplies the brake release pressure to the parking brake device by a pressure oil held in the accumulator. With this, it is possible to prevent a malfunction that a parking brake canot be released, thereby mobile work with the electric traveling vehicle cannot be carried out, thus contributing to improvement of work efficiency. |
