ABSTRACT:
A control system for use in controlling the positioning of a continuous hydraulic pipeline system of extensible type. The system includes automatic control apparatus responsive to pipeline or hydraulic transport position sensing apparatus which functions to maintain the pipeline apparatus in proper position automatically during operation. The control system is particulaly adapted for use in controlling position and tension in hose hauler vehicles for coal slurry transport in automatic mining operations, and serves to continually sense tension in the slack loop of the hose hauler vehicle to maintain the tension within predetermined limits thereby assuring proper positioning of the entire hose hauler vehicle and machinery train.
