Rigging
Make sure all wire rope blocks, tackle and fastenings have a sufficient
safety margin to handle the required load under all conditions. Do not
allow wire rope to contact sharp edges or make sharp bends which will
cause damage to wire rope, use a sheave. Refer to wire rope manufacturers
handbook for proper sizing, use and care of wire rope.
Safe Installation Procedures
1.
Do not use wire rope as a ground (earth) for welding.
2.
Do not attach a welding electrode to winch or wire rope.
3.
Never run the wire rope over a sharp edge. Use a correctly sized
sheave.
4.
When a lead sheave is used, it must be aligned with the center of the
drum. The diameter of the lead sheave must be at least 18 times the
diameter of the wire rope.
5.
Always maintain at least three full tight wraps of wire rope on the
drum.
Air System
The air supply must be clean, lubricated and free from moisture. A
minimum of 6,3 bar/630 kPa at the winch motor is required during
operation to provide rated winch performance.
Air Lines
The inside diameter of the winch air supply lines must not be smaller than
the sizes provided in the "SPECIFICATIONS" section. Before making
final connections to winch inlet all air supply lines should be purged with
clean, moisture free air or nitrogen. Supply lines should be as short and
straight as installation conditions will permit. Long transmission lines and
excessive use of fittings, elbows, tees, globe valves etc. cause a reduction
in pressure due to restrictions and surface friction in the lines.
Air Line Lubricator
Always use an air line lubricator with these motors. Use a lubricator
having an inlet and outlet at least as large as the inlet on the winch motor.
Install the air line lubricator as close to the air inlet on the winch motor as
possible.
• Lubricator must be located no more than 3 metres from the winch
motor.
• Shut off air supply before filling air line lubricator.
The air line lubricator should be replenished daily.
1.
LS600R, PS1000R, LS1500R and PS2400R winches: set lubricator
to provide 2 to 3 drops per minute of ISO VG 32 (SAE 10W) oil
(minimum viscosity 135 Cst at 40° C).
2.
LS2000R, PS4000R, LS5000R and PS10000R winches: set
lubricator to provide 6 to 8 drops per minute of ISO VG 32 (SAE
10W) oil (minimum viscosity 135 Cst at 40° C).
The four most important aspects of winch operation are:
1.
Follow all safety instructions when operating winch.
2.
Allow only people trained in safety and operation of the winch to
operate the winch.
3.
Subject each winch to a regular inspection and maintenance
procedure.
4.
Be aware of the winch capacity and weight of load at all times.
• Winches are not designed or suitable for lifting, lowering or moving
persons. Never lift loads over people.
• Winches equipped with a disengaging clutch are designed for pulling
applications only. Do not use these winches in lifting applications.

Air Line Filter
It is recommended that an air line strainer/filter be installed as close as
practical to the motor air inlet port, but before the lubricator, to prevent
dirt from entering the valve and motor. The strainer/filter should provide
20 micron filtration and include a moisture trap. Clean the strainer/filter
periodically to maintain its operating efficiency.
Moisture in Air Lines
Moisture that reaches the air motor through supply lines is a primary
factor in determining the length of time between service overhauls.
Moisture traps can help to eliminate moisture. Other methods, such as an
air receiver which collects moisture before it reaches the motor or an
aftercooler at the compressor that cools the air prior to distribution
through the supply lines are also helpful.
Mufflers
Make sure mufflers are installed in winch exhaust ports and are
functioning correctly.
For optimum performance and maximum durability of parts, provide an
air supply of 6,3 bar at the flow recommended in the
"SPECIFICATIONS" section, as measured at the motor inlet. The winch
should be installed as near as possible to the compressor or air receiver.
• Do not exceed the maximum specified operating pressure, 6,3 bar.
The winch overload valve will exhaust air if maximum pressure is
exceeded.
Winches are tested for proper operation prior to leaving the factory.
Before the winch is placed into service the following initial operating
checks should be performed.
1.
When first running the motor some light oil should be injected into
the inlet connection to allow good lubrication.
2.
When first operating the winch it is recommended that the motor be
driven slowly in both directions for a few minutes.
For winches that have been in storage the following start-up procedures
are required.
1.
Give the winch an inspection conforming to the requirements of
"Winches Not in Regular Use" in the "INSPECTION" section.
2.
Pour a small amount of ISO VG 32 (SAE 10W) oil in the motor inlet
port.
3.
Operate the motor for 10 seconds in both directions to flush out any
impurities.
4.
The winch is now ready for normal use.
OPERATION
An overload device is required on all winches with a rated capacity of
over 1 metric ton used for lifting applications.
The overload device is integrated into the winch air motor and prevents
the winch from lifting a load greater than the overload value listed in the
specifications chart. If an overload is detected, inlet supply air is stopped
and the winch will not operate.
If the overload device is activated the load must be lowered and reduced.
Alternative methods should be used to accomplish the task. To lower the
load reset the winch by pressing the "ON" button of the emergency stop
device and action the winch control for wire rope payout.
