INTRODUCTION AND THEORY OF OPERATION
The Tulsa worm gear winch is operated by turning the input of the worm using a
hydraulic motor or PTO driven sprocket and chain. The winch utilizes the adjustable,
spring applied, multiple disc oil brake that activates only during pay-out to provide
maximum efficiency during pay-in. The torque is transferred from the gearbox through
the drum shaft which is keyed to a mechanically actuated sliding clutch that when
engaged transfers the torque to the drum.

This manual is for design series 001. In the case of a major design change
implementation, a new design series designation number will be issued for the winch. A
new manual will also be created for that specific design series.

Winches, like any other kind of machinery, require a “break-in” to perform well and to
maximize their life. The following guidelines should be used in the break-in of Tulsa
Winches.
Use extreme care when first spooling cable onto the winch. DO NOT run the winch
at high speeds when performing this operation. Make sure that the cable is payed-out in
a straight line (to prevent kinks) and SLOWLY pay-in the winch to install the cable.
DO NOT exceed one half rated load or one half rated line speed for the first thirty
minutes of operation. This will insure that the worm and gear have an opportunity to
wear in properly. Periodically, check the gearbox for temperature rises and allow the
winch to cool down between pulls. Worm gear winches are designed and intended for
intermittent duty application only; using them in extremely long pulls may generate
excessive heat and shorten the life of the winch.
