Abstract
A traveling system for construction equipment is provided, which can secure an initial traveling manipulability regardless of a low-speed traveling or a high-speed traveling. If the high-speed traveling is selected and the traveling is manipulated, the inclination angle of a swash plate of a hydraulic pump is variably controlled, so that the discharge flow rate of the hydraulic pump exceeds a predetermined flow rate in comparison to the low-speed traveling.
