ABSTRACT:
A cross lever valve control device (1), especially for a lifting device such as a crane, with at least one manually actuated cross lever (2,3) which can be swivelled in first cross direction (K.sub.1) and in a second cross direction (K.sub.2), and with at least two control valves (5, 6, 9, 10) which each have one movable valve body (11, 12, 15, 16), cross lever (2, 3) being coupled to valve body (11, 16) of first control valve (5, 10) and valve body (12, 15) of second control valve (6, 9) such that first control valve (5, 10) can be actuated by moving cross lever (2, 3) in first cross direction (K.sub.1) and second control valve (6, 9) can be actuated by moving cross lever (2, 3) in second cross direction (K.sub.2). To make available a maximum number of functions of cross lever valve control device (1) without the need to release cross lever (2, 3), it is provided as claimed in the invention that cross lever (2, 3) is coupled to valve body (13, 14) of third control valve (7, 8) such that third control valve (7, 8) can be actuated by rotary motion of cross lever (2, 3) around its longitudinal axis (L) in one and the other direction.
