摘要： A material handling device for releasably gripping objects of various sizes is disclosed. The device comprises a pair of opposed gripping pads operable between a closed position in which the gripping pads engage opposite sides of the object and an open position in which at least one of the gripping pads is spaced from the object. Springs urge the gripping pads apart, and fluid motors apply a force opposed to the springs to move the gripping pads toward one another when fluid pressure is applied to the fluid motors. A fluid controller applies an adjustable minimum fluid pressure to the fluid motors to thereby adjustably limit the maximum distance between the grippers.
