    摘要: A load control device for a working tool of a construction vehicle in which a signal detected by a speed detector or a traction force detector is fed back to produce a deviation signal between said signal and a desired signal. A memory unit has stored a desired value of speed or traction force for each acceleration and outputs the desired signal corresponding to an acceleration signal from an acceleration detector. The working tool is moved up or down according to the deviation signal and, through the feedback mechanism, the load applied to the working tool is automatically controlled so as to enable the construction vehicle to work at maximum work efficiency without operator's efforts.
