摘要： Disclosed is a method for controlling travel of construction heavy equipment with electronic joysticks (70a,70). The method includes the steps of; inputting a joystick travel function selection signal (80), first manipulation signals of the joysticks (70a,70) and second manipulation signals of acceleration pedals (70b,70c) into a controller (100); determining whether a joystick travel function (80) is selected or released; when the joystick travel function (80) is selected, performing long-distance travel; and when the joystick travel function is released, performing a work. The working unit such as the boom and the arm and the traveling unit can be selectively driven by using the electronic joystick (70,70a). Thus, the driver can control the travel of the construction heavy equipment in a comfort sitting posture.
