INTRODUCTION AND THEORY OF OPERATION
The Rufnek series planetary winch is designed to use a high-speed gear motor, driving through a multiple
disc brake, through three planet sets to the cable drum.
The multiple disc brake is spring applied and hydraulically released through a port in the brake housing.
During inhaul, the brake is not released since the load is driven through the one-way cam clutch, bypassing
the brake. When the load comes to a stop, the cam clutch locks up and the load is prevented from moving by
the brake.
The brake and brake valve receives its signal any time the winch is in pay out. With the brake fully open at
about 340 PSI the brake valve will open and dynamically control the lowering of the load.
MAINTENANCE
Tulsa Rufnek series planetary winches, like any other piece of machinery, need to be periodically serviced
and well maintained to insure proper operation.
Good maintenance consists of four steps.
1. A daily inspection to insure that there are no oil leaks present and that all mounting bolts and other
fasteners are tight, and that the wire rope is in good condition.
2. Changing the oil in both the gearbox and the brake section. (Severity of use will determine the need for oil
changes but it should be checked at a minimum of every 500 hours. Factors such as extremely dirty
conditions or widely varying temperature changes may dictate even more frequent servicing)
.
3. Lubing drum bushings and sliding clutch with grease thru grease fittings located on drum barrel and clutch.
4. Complete teardowns and component inspections.
(Again, severity and frequency of use will determine
how often this should be done) . If the equipment that this winch is mounted to is subject to standards for
this type of inspection, then those standards must be followed. If oil changes reveal significant metallic
particles then a teardown and inspection must be made to determine the source of wear.
Tulsa Rufnek series of winches are shipped from the factory with Mobilube SHC SAE 75W-90 gear lube in
the gearbox and automatic transmission fluid in the brake section. This oil should be satisfactory for operation
in ambient temperatures from -40
°
F to +110
°
F. If your work calls for operation in temperatures outside this
range, contact Tulsa Winch for recommendations.
Gearbox oil is drained by removing the fill plug (item 39) located at the top of the gear housing (item 10).
Remove the drain plug (item 31) located at the bottom center of the gear housing. Examine the used oil for
signs of significant metal deposits and then dispose of it in a proper manner. Reinstall the drain plug and fill
the gearbox with the proper amount of new Mobilube SHC SAE 75W-90 gear lube through the fill hole.
Replace the fill plug. Make sure the breather (item 93) is operational and replace if necessary.
Drain the brake section by removing the drain plug and breather in the brake cover (item 18). Inspect the
oil for signs of metallic particles and/or burning and re-install the drain plug. Fill with one half to one pint of
automatic transmission fluid, or hydraulic oil and replace the breather.
