Operation
PERSONAL PROTECTIVE EQUIPMENT
Wear gloves to protect against rope abrasion or chafe when operating winch.
LIFTING LOAD
1. Feed the rope through the pigtail and, starting at the base of the winch, wind rope onto drum in a clockwise
direction. Use at least four complete turns, but no more than six, depending on rope diameter. Excess turns
may cause rope to override or may cause excessive friction. (
See images
).
WARNING!
Always put a minimum of 4 turns on winch drum. Fewer turns can severely decrease holding
power which may result in rope slippage or failure to hold load, causing lifted load to fall, possibly resulting
in severe injury or death.
IMPORTANT!
Keep fingers, loose clothing, hair etc away from winch. Area around winch handle should
be kept clear of people and objects at all times. Be sure to keep loose rope near winch to prevent
tripping.
Excessive turns at base of winch
Rope override
WARNING!
Never allow rope to override on winch drum. This can cause rope to jam and can prevent load
from being lifted/lowered. Tension on loaded rope must be relieved to clear override. This procedure car-
ries a risk of serious injury or death if load drops or becomes uncontrollable.
2. Pull rope through to take up any slack, then load into spring-loaded, self-tailing jaws by winding rope clockwise and
pulling tight to engage. Self-tailing jaws act as locking mechanism so operator does not have to pull rope in or let it
out while rotating the handle.
WARNING!
Rope must be securely pulled into self-tailing jaws. Do not rely solely on rope turns to hold
load. Stripper arm must be positioned correctly so that the weight of rope or any other force does not
cause the rope to be pulled out of the jaws (
see images overleaf
). Check that rope remains secured in self-
tailing jaws while cranking.
Failure to secure rope in jaws may cause rope slippage which can cause lifted load to fall, possibly resulting
in severe injury or death.
