    摘要: A control unit for controlling the hydraulic system of a con­struction machine, such as a hydraulic shovel, having a structure capable of being simply and quickly changed from one setup for another setup suitable for a desired mode of control operation. The control unit comprises a control lever (1) pivotally supported for movement in longitudinal and transverse directions, and first and second link rods (5,6) for transmitting the operating force of the control lever to first and second hydraulic control valves (5, 7) when the control lever is shifted in the longitudinal and transverse directions, respectively. An operating force transmitting member is put on the control lever so as to be rotatable about the axis of the control lever, and a locking member is mounted on the control lever so as to be slidable along the axis of the control lever and so as to be unable to rotate relative to the control lever. In changing the setup of the control unit, the locking member is disengaged from the operating power transmitting member, the operating power transmitting member is turned through an angle of 90°, and then the locking member is brought into engagement with the operating force transmitting member to lock the operating force transmitting lever in place relative to the control lever.
