Abstract
A control lever structure for a mechanical finger clamp having a grip and first and second members projecting therefrom in opposite directions from each other. The mechanical finger clamp comprises a mounting member, and a plurality of articulate fingers pivotally connected to the mounting member, each articulate finger having a base portion and a leading end portion pivotally connected to the base portion. Pivotal movements of the articulate fingers are caused by hydraulic cylinders. A plurality of switches are mounted on the grip and the first and second members for selectively operating the hydraulic cylinders via solenoid-operated control valves. The arrangement of the plurality of switches is such that the movements of operator's fingers for operating the switches are similar to the movements of the articulate fingers.
