6. POWER DRIVE APPLICATIONS
In applications involving repeated positioning activities or long vertical entries, it is
sometimes desirable to have a powered winch rather than relying on manual
cranking.
The winches are designed with a unique input drive hub (see Figure 5) that allows
for convenient switching between manual crank and powered operation while
maintaining a manual backup in the event of power failure or mechanical
problems.
Depending on the nature of the application, the regulations governing the use of
powered winches to raise and lower equipment in various jurisdictions, and the
type and specifications of power drills available, there are several configurations
of Power Drive accessories that may be appropriate (see Figure 6).

While Tuff Built Products recommends the above Milwaukee products, any drill meeting the same specifications of the above drills can

The use of HIGH SPEED (RPM) drills will result in damage and premature failure of winch components.
