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.
