PURPOSE: A device and a method for manipulating travelling heavy equipment are provided to improve convenience without considering experience of a user in a specific manipulating method. CONSTITUTION: A device for manipulating travelling of a construction equipment comprises pilot pump(Pp) and main pump driven by an engine; a travelling motor(T/M) actuating by receiving hydraulic oil from the main pump; a control valve controlling actuation of a travelling motor by pilot pressure oil supplied form the pilot pump; a shuttle valve outputting the pilot pressure oil to the control valve by receiving from the first and second diverged pilot oil passages; a first valve mounted on the first diverged pilot oil passage; a pedal(3) controlling opening of the first valve; a second valve installed on the second diverged pilot oil passage; and a lever(4) controlling opening of the second valve. Thereby, a driver selects manipulating type in single equipment and operates the equipment without experience.
