Ramsey Winch HD-200 (JERR-DAN) - Manual (Page 8)

HYDRAULIC SYSTEMS
Refer to performance charts, below, to properly match your hydraulic system to the
HD-200 winch performance. The charts consist of:
1. Line pull (lbs.) first layer vs. working pressure (P.S.I.). STATIC (solid line)
refers to hoisting a suspended load from rest; DYNAMIC (dashed line) refers
to maintaining the motion of a moving load.
2. Line speed, first layer (F.P.M.) vs. gallons per minute (G.P.M.).
Performance based on a motor displacement of 3.6 cubic inches with 15 GPM max-
imum flow rate.
