Ramsey Winch H-930R DOW-LOK w/Air Shifter for Szummar - Manual (Page 4)

HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts, below, to properly match your hydraulic system to the H-930 Model winch performance. The
charts consist of :
(1) Line pull (lb.) first layer vs. working pressure (PSI)
(2) Line speed, first layer (FPM) vs. gallons per minute (GPM).
Performance based on a motor displacement of 24 cubic inches with 30 GPM maximum flow rate. See page 17 for motor port
size.
