Abstract:
An apparatus for changing a combination of control devices and actuators, comprising:two, left and right, first control devices for outputting a plurality of first manipulation direction signals according to a plurality of manipulation directions; two, left and right, second control devices for outputting a plurality of second manipulation direction signals according to a plurality of manipulation directions; actuators for left and right traveling bodies, which are provided for each of the left and right traveling bodies a vehicle for actuating the left and right traveling bodies in respective directions by driving in a driving direction corresponding to an input driving signal; and actuators for at least two working machines, which are provided for each of at least two working machines for actuating the at least two working machines in respective directions by driving in a driving direction corresponding to an input driving signal; in which the combination of manipulation directions of the first and second control devices and driving directions of the actuators is changed, wherein a first switching valve for switching the combination of a plurality of input signals and a plurality of output signals and a second switching valve for switching the combination of a plurality of input signals and a plurality of output signals are provided, the first manipulation direction signals which are output from the first control devices and the second manipulation direction signals which are output from the second control devices are input as input signals to the first switching valve and the second switching valve, and a predetermined output signal of the output signals that are output from the first switching valve is input as an input signal to the second switching valve, and the output signals, excluding the predetermined output signal input to the second switching valve, among the output signals of the first switching valve and the output signals of the second switching valve are input as driving signals to the actuators for the traveling bodies and the actuators for working machines.
