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.
NOTICE
•
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 (10W) oil (minimum
viscosity 135 Cst at 40° C).
2.
LS2000R, PS4000R, POWAIR35, LS5000R and PS10000R winches: set lubricator to provide 6 to 8 drops per minute of ISO VG 32 (10W)
oil (minimum viscosity 135 Cst at 40° C).
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.
Motor
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.
CAUTION
•
Do not exceed the maximum specified operating pressure, 6.3 bar. The winch overload valve will exhaust air if maximum pressure is
exceeded.
Initial Operating Checks
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 (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.
