4.2.3 Raising or Lowering a Worker
A worker attached to the winch line is lowered by cranking the winch handle counterclockwise, and raised
by cranking the winch handle clockwise. DO NOT use the winch if the rotation of the winch handle is
reversed, or if the winch does not make a regular clicking sound when cranking the winch handle in a
clockwise direction.
Crank the handle at a smooth and steady pace that you find comfortable to maintain. Wear gloves if your
hands will come in contact with the winch line.
Maintain sufficient tension on the winch line, either from the weight of the worker or manually, to ensure
that the line winds evenly onto the spool. Do not allow any slack line to accumulate between the winch
and the worker if there is any risk of a fall occurring. Serious injury or death may result if a worker falls
while connected to a slack winch line.
5. 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 Jackpod Series of 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.
Figure 5, Winch Input Drive Hub
Depending on the nature of the application, the regulations governing the use of powered winches to raise
and lower workers 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).
