Comeup CWL-80 User manual

Compact 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

A Winch is designed to give safe and dependable service if operated

according to the instructions. 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.

1.The winch is not to be used to life, 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.Come-Up takes no responsibility for the subsequent performance of mechanical

components if oil possessing properties other than what Come-Up recommends is

used

II. Methods of Operation

Plug Insertion

Insert the plug of switch cable

into the receptacle of the winch.

Tighten it by turning the locking

ring clockwisely.

Be sure to fix the switch cable

by snap hook. Do not allow the

cable to be caughted by wire rope and drum.

Up And Down Control

To lift a load, press the up button, the drum will rotate in the lifting direction.

To lower a load, press the down button, the drum will rotate in the lowering

direction.

Wire Rope Replacement

Insert the wire rope into the hole of drum and fix it with a P. T. screw, then press

the "UP" button of switch for rotate the drum in the lifting direction.

Wind the wire rope accurately around the drum, and a irregular winding will cause

the load to be swing, thus damaging the wire and reducing the lift of winch.

When replacing, according to the following procedures.

*Pull out a R-dowel "D" from the round head pin "C".

*Pull out a round head pin "Cc from hook body "A".

*Put a wire rope "B" into the hole of hook body "A", and insert a round head pin

"C" through wire rope and fixture hole of hook body "A".

*Insert a R-dower "D" into the hole of round head pin "C".

Carbon Brush Replacement

The carbon brush can be used for about 100 working hours.

It shall be replaced immediately if its length left to 7.5mm.

Any negligence of replacement of it may do cause damage to motor.

Remove the brush cap and replace it accordingly.

Oil Replacement

Gear lubrication is an important component in insuring the long life of your winch.

The type of lubricant will have a great influence. The gear oil your winch was

shipped with is Castrol Alpha Series, SP-220, a viscosity ( cSt ) is 226.14/19.5 at

40℃/100℃. Consult your local lubricant distributor on the selection that best fits your

climate and application.

The initial lubricant should be changed after the first 10 hours of operation. Subsequent

changes of 100 cc for CWL-80 and 300 cc for others should be scheduled every 250

hours of operation or annually.

magnetic control box should be suggested.

III. HandlingPrecautionsAndCalculations

HandlingPrecautions

The operator of winch in some cases is required for qualifications according to

applicable laws and ordinances.

Prior to starting of use, carry out the daily checking without fail, and use after

confirming the safety of function.

Don't use exceeding the lead rated.

The operator of winch must not be apart from the operating position under the

loading condition.

Carry out the operation of lifting and lowering after stopping the winch once, and

avoid the rapid speed operation as far as possible.

Even in the condition where the rope is feed out at most, the rope must remain by

five more windings on the drum.

Record the daily operating time and take into consideration so as to obtain the

suitable time for intermediate inspection and arrangement.

Calculating Head Loads

P: Rope tension

η: Sheave coefficient

θ: Angle

W: Load

μ: Friction factor

Calculating Fleet Angle

The winch should be mounted as close to center and as perpendicular as possible to

the direction of the line pull. This will keep the wire rope fleet angle centered 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. This could cause failure of the winch or wire rope, resulting in damage,

injury or death.

Experience has shown that the best wire rope service is obtained when the

maximum fleet angle is not more than 1.5°∘for smooth drums.

The distance from centre of the rope drum till the first rope sheave or roller fairlead

shall in the ideal case be 19 times the drum width
