2.1
General Theory of Operation
2.1.1
THE PULL REQUIRED to move the load must not exceed the load rating of
the winch. Consider the total force required to move the load, not the weight
of the load.
2.1.2
THIS EQUIPMENT CAN develop forces that will exceed the load rating.
It is the responsibility of the equipment user to limit the size of the load.
Inspect the equipment regularly for damage according to the instructions
contained in this manual and in the component manufacturer’s information.
2.1.3
USE A LOAD BRAKE on all winches used to lift loads. When engaged,
they lock the drive train to the winch frame, thereby stopping drum rotation
when the control is released or placed in the neutral position.
2.1.4
PERFORMANCE RATINGS of the equipment are affected by the amount
of wire rope wound on the drum, air power supply, and the way the winch is
used.
a
DRUM CAPACITY depends on how tightly and evenly the wire rope is
wound on the drum. Actual drum capacities are usually 25-30% less than
values shown in performance tables, due to loose winding and overlapping.
The outermost layer of rope in any load case must be a minimum of 2.5 rope
diameters below the edge of the drum flange.
b
LINE SPEED increases with each additional layer of wire rope wound onto
the drum. Line speed will also vary with rider weight and air power supply.
2.1.5
DUTY RATINGS refer to the type of use the equipment is subject to.
Consider the following when determining duty rating.
a
ENVIRONMENT: harsh environments include hot, cold, dirty, wet,
corrosive, or explosive surroundings. Protect the equipment from harsh
environments when possible.
b
MAINTENANCE: poor maintenance, meaning poor cleaning, lubrication,
or inspection, leads to poor operation and possible damage of the equipment.
Minimize poor maintenance by carefully following the instructions contained
in this manual.
c
LOADING: severe loading includes shock loading and moving loads that
exceed the load rating of the equipment. Avoid shock loads, and do not
exceed the load rating of the equipment.
d
FREQUENCY OF OPERATION: frequent start and stop functions increase
wear and shorten the life span of the gear train and load brake components.
Lengthy operations cause lubrication to become hot, which also decreases
the life span of the gear train and brake. Increase maintenance of the
equipment if used in frequent operations.

Important!
• Limit nonuniform winding by
keeping tension on the wire rope
and by maintaining the proper
fleet angle.
• It is your responsibility to detect
and account for different factors
affecting the condition and
performance of the equipment.
• When determining if the rider
will exceed the load rating,
consider the total force required
to lift the person (plus harness
and related devices), and not just
the static weight of the person
