The present invention relates to a travel control system composed of left and right main pumps supplying oil; left and right driving motors receiving the oil from the left and right main pumps to rotate; left and right driving spools installed between the left and right main pumps and left and right driving motors and controlling an oil passage; left and right driving levers controlling a travel of an excavator; and a driving motor simultaneous driving device enabling the excavator to move forward or move backward by using one between the left and right driving levers. The present invention is characterized in that the driving motor simultaneous driving device includes a second forward/backward movement switch and a driving motor control spool installed on a communication line connecting a driving oil line of the right driving motor and a driving oil line of the left driving motor. The travel control system for construction equipment according to the present invention includes the driving motor simultaneous driving device with the driving motor control spool formed on the communication line of the driving oil line of the right driving motor and the driving oil line of the left driving motor to operate the two driving motors simultaneously by operating one between the two driving levers or including a driving lever integrated device with a driving lever connecting member integrating the two driving levers, thereby being capable of moving forward or backward the construction equipment by operating one between the two driving levers. Therefore, the present invention enables the precise travel of the construction equipment such as forward/backward straight travel with ease. |
