Ramsey Winch RPH-15000 (CURRENT) - Manual (Page 6)

HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts below to properly match your hydraulic system to the winch performance. The
charts consist of: (1) line pull (LB) first layer vs. working pressure (PSI); (2) line speed, first layer (FPM) vs. flow
(GPM). A motor spool directional control valve is recommended.
* Caution: Do not exceed 20 G.P.M. If exceeded, motor and winch may be damaged.
