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.
