Electric Winch
Thank you for purchasing a Winch. This manual covers operation and maintenance of
the winch. All information in this publication is based on the latest production information available at
the time of printing.
General Safety Precautions
The winch has been designed to give safe and dependable service if operated according to the
instructions. Please read and understand this manual before installation and operation of the winch.
Follow these general safety precautions:
Confirm that the winch complies with the using conditions.
Keep the winch secure strongly and the rope is not wound to be deviated to the drum.
Don't use unsuitable pulleys or accessories concerned.
Don't use unsuitable rope in construction, strength or having any defects.
Pay attention to the grounding, it provides a path of least resistance for electric current to reduce
the risk of shock.
Check the winch for smooth operation without load before loading operation.
Make sure the wire rope to be wound evenly in the first layer on the drum, rewind it if a mixed
windings in existence.
If a wire rope is found an uneven winding or accumulated at one side of the drum, align it adequately.
WARNING
！
1. The winch is not to be used to lift, support or otherwise transport personnel.
2. A minimum of five (5) wraps of rope around the drum is necessary to support the load rated.
3. The owner and/or the operator shall have an understanding of these operating instructions and the
warning before operating the electrical winch. Failure to follow these warnings may result in loss of
load, damage to the winch, property damage, personal, or fatal injury.
4. The owner shall retain this manual for further reference to important warnings, installation, operating
and maintenance instructions.

II. Handing Precautions
● It is forbidden to lift loads above
the rated capacity of the winch
● Ban on transporting persons ● Don’t ignore fault accessories
● Don’t stand under winching
operation
● Do connect the power lead on the
main power source directly and
fasten them
● Don’t operate hoist in rain or snow
● Do perform maintenance on
schedule
● Do anchor crane with ballasted
container and wire rope

III. Winching Principles
Percentage Duty Cycle
WARNING
！
Never hoist over the rated percentage duty cycle.
The life of the winch is depending on the conditions of the load and working frequency.
In the long time operation, make sure to use the machine within its continuous ratings.
Continuous ratings means the percentage duty cycle (%ED) is subject to the rated voltage,
rated frequency and a 63% of rated load.
Percentage duty cycle (%ED)＝ X 100 (%)
Tb: total sum of overall loadings operating hours.
Ts: total sum of stopping hours.
Tb + Ts = approximately 1 to 10 minutes.
For this reason, all electric winches are rated at a 25% percentage duty cycle (%ED).
Tb
Tb + Ts
Load Rated
Load and speed vary according to how
much wire rope is on the drum. The first layer
Top layer (Max.speed Min.load)
Half layer (Med.speed Med.load)
First layer (Min.speed Max.load)
of rope on the drum delivers the slowest speed
and the maximum load. A full drum delivers the
maximum speed and the minimum load. For this
reason, all electric winches are rated at their
top layer of wire rope on the drum.

Calculating Fleet Angle
● The winch should be mounted as close to centre
and as perpendicular as possible to the direction
of the line pull. This will keep the wire rope fleet
angle centre on the drum as small as possible.
● If the proper fleet angle is not maintained, the wire
rope could wind onto one side of the drum.
Experience has shown that the best wire rope service is obtained if the maximum fleet angle
is not more than 1.5° for smooth drum and 2° for grooved drum.
For example, the correct distance varies according to drum length.

D/d Ratio
It means ratio of pitch circle diameter of drum to the rope diameter.
In principle, a 12:1 D/d ratio is suggested for most pulling application and a 15:1 D/d ratio for
lifting and lowering applications. For example, a CP-200 comes with a 94 mm dia. drum and
a 6 mm x 30 m wire rope, therefore its D/d ratio is calculated as follow.
D/d ratio = ( 94 + 6 mm ) / 6 mm = 16.67 times
Rope Safety Factor
The working coefficient of the wire rope shall be determined from the ratio of the minimum
breaking force of the rope and the maximum possible lifting capacity.
In principle, a 3.5 times of rope safety factor is suitable for most pulling applications and a 5
times for lifting and lowering applications. For example, a CP-200 comes with a 6 mm x 30 m
wire rope with 2,010 kg minimum breaking force, therefore its rope safety factor is calculated
as follow.
Rope safety factor = 2,010 kg / 200 kg = 10 times
