Patent ID: 6955048

Claim:
A control system for controlling motor functions of a drive, comprising at least two hand switch boxes spatially separate from the drive to be controlled and which for the control of a first and second motor function of the drive have a first and second double action cylinder with two oppositely actuated cylinder chambers for a hydraulic flow medium that are connected by means of control lines carrying the hydraulic flow medium with the cylinder chambers of a first and second working cylinder allocated to said first and second motor function, whereby the outputs of the first and second double action cylinder and first and second working cylinder are parallel connected and at least one shut-off valve device is provided for in the control lines for the controlled switching on and off of the hand switch boxes wherein that parallel to the first and second working cylinder or the oppositely actuated cylinder chambers of the first and second working cylinder is a further valve, which when opened enables a hydraulic connection between the oppositely actuated cylinder chambers of the first and second working cylinder, wherein said first motor function is actuated by said first double action cylinder in a first swivel movement of a hand lever from a neutral position and said second motor function is actuated by said second double action cylinder in another swiveling of the hand lever.
