WINCH FRAME MOUNTING
Use (8) 1/2" diameter grade 5 or better bolts to attach mounting frame to the wrecker.
CABLE INSTALLATION
The RPH-20000 winch has two tapered pockets cast into the drum. One pocket is for installations
with the wire rope wound over the drum. The other pocket is for an underwound wire rope. When
properly used, the wedge pocket design is one of the most secure anchoring methods available.
1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of wire
rope, opposite hook, with plastic or similar tape to prevent fraying.
2. Slide the wire rope through narrow end of pocket against the drum flange and wrap the wire rope
around the anchor “puck” and pull the wire rope and anchor back into the wide end of the pocket.
Use a soft hammer to drive the back side of the wire rope, firmly seating the wire rope and anchor,
into the pocket.
3. Carefully run the winch in the “reel-in” direction. Keeping tension on end of cable, spool all the
cable onto the cable drum, taking care to form neatly wrapped layers.
The wire rope can easily be removed from the drum by driving the anchor out the wide end of the
pocket.
HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts, below, to properly match your hydraulic system to RPH-20000 winch
performance. The charts consist of:
(1) Line pull (lb.) first layer vs. working pressure (PSI) and (2) Line speed, first layer (FPM) vs. gallons per
minute (GPM). Performance based on a motor displacement of 8.0 cubic inches with 15 GPM maximum flow
rate. See page 13 for motor port size.
