Building Quality Winches Since 1934
RKI has been manufacturing quality winches to serve the needs of industrial, commercial
and private users for over seventy years.
Our winches are used all over the world in the manufacture of cranes, aerial devices,
processing plants, agriculture equipment, refuse collection and oilfield rigs.
Cranes
Aerial Devices
Processing Plants
To ensure the highest quality, every one of our products is designed, tested, and built in
our Houston, Texas facility. If one of our standard winches or options does not meet your
specific requirements, we can provide custom drums, shafts, mountings and accessories to
match your exact specifications.
High Quality Features:
> Aluminum bronze worm gears
> Line pull up to 20,000 pounds
> Hardened steel worms
> Standard options include capstans,
roller assemblies, drum guards,
drum-shaft extensions, worm brakes,
drums keyed to shaft
> Tapered roller bearings on wormshaft
Agriculture
Refuse Collection
> Fabricated steel drums will not break
> Hundreds of standard configurations
> Available for any power source:
mechanical, hydraulic, electric
> Oil-cooled plate type worm brakes
Oilfield Rigs
Superior Pulling Power
Cement Plants
Many industries use our winches
for everyday jobs or incorporate
our winches into products to serve
their special applications.
Utility Companies
2
Utility companies use our
winches to tension cable for
power line installations; mines and
cement plants use our winches to
run conveyers; and loggers use
our winches to load trees for
transport. In Texas, many of the
light towers that line our major
highways have an RKI winch
installed in the base that is used
to lower and raise the light rings
for easy maintenance.
> Custom drums, shafts, and mountings
available to meet your individual needs
Note: Not all features apply to all winches.
Light ring on top of pole is
lowered by an RKI winch for
maintenance.
Shown here is the area the
RKI winch is installed in the
light pole.

CHOOSING A WINCH
CHOOSING A WINCH: THINGS TO CONSIDER
1. Maximum Line Pull
5. Drum Clutch
The maximum line pull of a winch depends upon
which cable layer is being used, as shown in the
chart on the previous page, and must not be
exceeded. For example, if you need to pull 8,000
pounds with 75 feet of cable on the drum, a Series
12 winch would be required since a Series 8 winch
is only capable of pulling 6,020 pounds with that
much cable on the drum.
If you wish to pull rope off the drum by hand, a
drum clutch is needed. If such freespooling is not
needed, a keyed drum will be more reliable.
6. Duty Cycle
Winches are rated for intermittent duty only.
Excessive use will cause high oil temperature
resulting in rapid oil deterioration, lower efficiency
and increased wear.
2. Line Speed
Do not exceed the line speed shown for mechanical
winches without first consulting the factory.
3. Power Source
Be sure your power source can meet the winch’s
requirements as shown in the table on the previous
page.
Applications that involve holding a suspended load
should have a worm brake. Some applications, such
as using a winch to free a vehicle that is stuck in
mud, do not need a worm brake. Winches with
brakes must have the cable wound according to the
brake setting. Winches with brakes can be ordered
either “overwind” cable spooled over the drum in
the direction of the brake housing or “underwind”
cable spooled under the drum in the direction of
the brake housing. See example at right.
6
Winch should be mounted with the worm shaft
horizontal and below the drum. Other arrangements
may not provide adequate lubrication. Worm brakes
must be mounted below the oil level or they will fail.
8. Special Requirements
4. Worm Brake
CAUTION: Remote control should be connected only
when vehicle is stationary and winch is being operated.
7. Mounting
Extra cable capacity, higher line speed, grooved
drum barrel, divided drum, galvanizing and stainless
steel shafts for improved corrosion resistance,
custom mounting, special shafts and power sources
are some of the modifications we have made.
