Ramsey Winch HD-234 - Manual (Page 8)

HYDRAULIC SYSTEMS
Refer to performance charts, below, to properly match your hydraulic system to
the HD-234 winch performance. The charts consist of:
1. Line pull (lbs.) first layer vs. working pressure (PSI). 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 (FPM) vs. gallons per minute (GPM).
Performance based on a motor displacement of 3.6 cubic inches with 15
GPM maximum flow rate.
