Hydrostatic drive system for mobile working machine, particularly industrial truck, has stop valve device controlled by safety device, where stop valve device is impinged in locking position of load channel in safety position

摘要

The hydrostatic drive system has a hydraulic load, which is operated by a control valve (1), particularly a control valve operated by the mechanical operating force of an operator. The control valve is connected with the load by a load channel (5). A stop valve device (7) is controlled by a safety device (10), where the stop valve device is impinged in the locking position of the load channel in a safety position (11a) of the safety device.
