RAMSEY HYDRAULIC PLANETARY WINCH MODEL RPH-8000-Y PLEASE READ THIS MANUAL CAREFULLY This manual contains useful ideas in obtaining the most efficient operation from your Ramsey Winch, and safety procedures one needs to know before operating a Ramsey Winch. Do not operate this winch until you have carefully read and understand the "WARNING" and "OPERATION" sections of this manual. WARRANTY INFORMATION Ramsey Winches are designed and built to exacting specifications.
CABLE INSTALLATION A decal on the top of the end bearing indicates the spooling direction of the cable. Another decal (located on brake housing) indicates the balls in the brake are in #1 slots. If the decals are damaged or unreadable, contact Customer Service for additional instructions to determine proper direction. 1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of cable, opposite hook, with plastic or similar tape to prevent fraying. 2.
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) and (2) line speed, first layer (FPM) vs. flow (GPM). STATIC (solid line) refers to hoisting a suspended load from rest; DYNAMIC (dotted line) refers to maintaining the motion of a moving load. A cylinder spool directional control valve is recommended.
OPERATION The best way to get acquainted with how your winch operates is to make test runs before you actually use it. Plan your test in advance. Remember, you hear your winch, as well as see it operate. Get to recognize the sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or shifting. Avoid conditions where load shifts or jerks occur, as they may indicate a dangerous situation.
TROUBLE SHOOTING GUIDE CONDITIONS POSSIBLE CAUSE CORRECTION DRUM WILL NOT ROTATE AT NO LOAD Brake damaged. Inspect and replace brake. Gears damaged. Inspect and replace damaged gears. Load greater than rated capacity of winch. Refer to Specifications pg.1 for line pull rating. Low hydraulic system Check pressure. Refer to HYDRAULIC pressure. SYSTEMS performance charts pg. 3. Low hydraulic system flow rate. Check flow rate. Refer to HYDRAULIC SYSTEMS flow chart page 3. Motor worn out.
ADJUSTING THE BRAKE All parts of the oil-cooled automatic safety brake are bathed in oil. When the brake wears to the point that the load begins to drift, the brake can be adjusted as follows: 1. Loosen the lock nut on the adjusting screw (see drawing on page 9). 2. Increase the brake torque by turning the adjusting screw clockwise. CAUTION: Only 1/4 turn is usually required to adjust the brake. Over-tightening can cause overheating, and damage to the brake parts.
INSTRUCTIONS FOR OVERHAUL OF RAMSEY WINCH MODEL RPH-8000-Y DISASSEMBLY Remove frame assembly (item #2) by unscrewing (8) capscrews (item #19). Remove breather plug and reducer (item #35 & #40) from winch. Drain oil from winch by removing plug (item #41). Remove motor (item #36), coupling (item #32) from winch by unscrewing capscrews (item #25). If coupling is being replaced, be sure pin (item 42) is installed. Tap motor lightly to disengage.
Remove tie plates (item #14) from end bearings (items #8 & #9) by unscrewing capscrews (item #19), as shown. Slide motor end bearing (item #8) from drum (item #1) and drum from gear housing end bearing (item #9). Remove input shaft (item #13) from end bearing. Inspect teeth of gear (item #6) for signs of wear. If necessary replace gear by removing snap ring (item #48) and thrust washer (item #51). Slide new gear over splines of shaft and against snap ring on shaft.
Remove brake housing (item #10) from end bearing (item #9) by unscrewing (4) capscrews (item #24). Remove gasket (item #34), coil spring (item #49), flat spring (item #4), retainer plate (item #12), composition brake discs (item #33), and cam plate (item #5). Remove hub (item #11) with plug (item #43)--which is press-fitted in the hub I.D. Inspect the seal (item #38) inside of gear housing bore, and replace if necessary. Inspect brake discs. Discs are 1/4” thick when new, replace if thinner than .200 in.
Remove o-ring (item #37) and bushing (item #16) from motor end bearing (item #8). Press new bushing onto end bearing and dip o-ring in oil and seat into groove of end bearing. Remove seal (item #46) from gear housing end bearing (item #9). Loosen nut (item #28) and remove nylon setscrew (item #23) and remove ring gear (item #7) from gear housing end bearing, if necessary. Remove bushing (item #18) from gear housing end bearing (item #9). Press new bushing (item #18) into place in end bearing.
Generously apply grease (MOBILITH SHC 007) to teeth of ring gear (item #7), teeth of planet gears in drum (item #1) and to bushing in end bearings (item #8 & #9). Apply grease to teeth of gear (item #6) and to splines of shaft (item #13). Place splined end of shaft into splines of hub in brake housing end bearing (item #9). Place drum over shaft and rotate drum to engage planet gears with output gear on shaft and ring gear in end bearing.
Before installing motor, check brake adjustment (refer to page 6, ADJUSTING THE BRAKE). Place splined end of coupling (item #32), with spirol pin (item #42) installed, inside of motor end bearing housing (item #8) and slide over splines on end of input shaft. Place o-ring (item #39) around motor pilot. Mount motor (item #36) to end bearing by aligning key on motor shaft with keyway in coupling.
