ABSTRACT:
A device for controlling the operation of power excavators includes a control lever which is handled simply by one hand, which is different from the prior art systems having multiple control levers necessarily handled by both hands. The control lever consists of a plurality of links which are jointed together in such a way that the intuitive handling directions of the links are identified with the actual moving directions of the actuators. The control lever thus adds significant convenience for the operator when operating the actuators of the excavator. An excavator with the above control device can be easily and effectively operated by an unskilled operator even for delicate work such as a land finishing work or loading work, both of which tasks are generally known in the art to require a highly-skilled operator.
