HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts, below, to properly match your hydraulic system to H-800 Dow-Lok® winch per-
formance. The charts consist of :
(1) Line pull (lb.) first layer vs. working pressure (PSI). STATIC (solid line) refers to hoisting a suspended load from
rest; DYNAMIC (dotted line) refers to maintaining the motion of a moving load.
(2) Line speed, first layer (FPM) vs. Flow, gallons per minute (GPM).
Performance based on a motor displacement of 14.9 cubic inches with 30 GPM maximum flow rate. See page 17
for motor port size.
