Abstract

PURPOSE: To enable safety and smooth operation by constituting the captioned apparatus so that manual speed-change operation can be carried-out, taking preference to automatic control.
CONSTITUTION: When a manual-automatic selecting switch 19 is set in automatic, automatic control is performed by the output of a load discriminating circuit 20. When the working load is smaller than the proper load,if the A terminal of the comparator 14 which compares the speed position signal with the travelling speed signal is at H position, an up-down counter 15 exectues up-count. If the B terminal is at H position, the up-down counter 15 executes down-count, and each acceleration or deceleration is carried-out until the traveling speed signal becomes equal to the speed position signal set by an operating lever 10. While, when the working load is larger, the up-down counter 15 executes up down-count, and the travelling speed signal deceases. When the working load becomes equal to the proper load, down- count stops.
