Ramsey Winch HDP35000 - Plantetary Industrial Winch - Manual (Page 5)

HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts to properly match your hydraulic system to HDP-35000 winch performance.
The charts consist of:
(1) Line pull (lb.) fi rst layer vs. working pressure (PSI) and (2) Line speed (FPM) fi rst layer vs. fl ow (GPM).
Performance is based on a motor displacement of 11.9 cubic inches with 25 GPM maximum fl ow rate. See
page 10 for motor port size.
