Abstract:
To reduce load on the operator and to establish traveling stability in the steering operation of a construction machine that has a pair of right and left traveling devices, and an engine as a driving power to the right and left traveling devices, a controller is provided which is responsive to a switch for traveling to drive or stop both a right and a left traveling devices. A switch for steering causes the controller to change the direction of travel of the construction machine, and the controller also acts to reduce the engine speed in accordance with the operation amount of the switch for steering.

Claim (Index 1):
A travel control system of a construction machine comprising:\n left and right traveling devices; an engine as a power source for the left and right traveling devices; left and right manipulators for traveling that are operated to drive the left and right traveling devices respectively; a work device for executing work other than traveling; a manipulator for work that is operated to drive the work device, the improvement comprising\n a switch for traveling that is provided separately from the left and right manipulators for traveling and operated to output a signal irrespective of a position of the left and right manipulators for traveling to drive and stop both the left and right traveling devices, \n a manipulator for steering that is operated to output a signal to change a direction of travel when the traveling devices are being driven based on an operation of the switch for traveling, and \n travel control means for controlling the left and right traveling devices based on operation signals output from the switch for traveling and the manipulator for steering, wherein the travel control means performs steering control by reducing a speed of either the left or right traveling device in accordance with an operation position and operation amount of the manipulator for steering, and lowering a speed of the engine in accordance with the operation amount of the manipulator for steering.
