HYDRAULIC SYSTEMS

Refer to the performance charts, below, to properly match your hydraulic system to the H-300 Series winch perform-
ance. The charts consist of:
1. Line speed, first line (F.P .M.) vs. gallons per minute (G.P .M.) and
2. Line pull (lbs.) first layer vs. working pressure (P .S.I.). STATIC (solid line) refers to hoisting a suspended load
from rest; DYNAMIC (dotted line) refers to maintaining the motion of a moving load.
Performance based on a motor displacement of 4.5 cubic inches with 15 GPM maximum flowrate. See page 13 for
motor port size.
