The Drinking Water Discharge Winch System is an electro-hydraulic Winch System composed of three
Hydraulic Power Package
Each component are separate units with the only inter-connection being hydraulic hoses.
Drive System Analysis
A theoretical system drive analysis was conducted to establish component selection and input power
requirements. The inputs into the analysis were as follows:
10,000 lbs pull @ mid layer
18,000 lbs brake @ mid layer
25 FPM hose speed @ mid layer
The basic winch configuration was dictated by available deck space. This limitation established a winch hub O.D. of
102.5 inches. Assuming five wraps of a 6-inch O.D. hose, the mid layer diameter becomes 132.5 in O.D. (66.25-inch
radius). The above values become inputs into the Drive System Analysis.
The following Tables at the ends of this section are a summary of the Drive System Analysis:
