Since the functions required for each work are different, the electric system is generally different between the medium and large construction machines and the small construction machines. At that time, the control device (controller) that moves each actuator of the construction machine tends to increase in size because of the large number of inputs and outputs in medium and large construction machines.
On the contrary, in small construction machines, the number of inputs / outputs is small, so many of them are small.
