3-4.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.
Fleet angle of 1.5∘is the equivalents of approximately 19 cm of lead for each
centimeter of overall drum width.

3-5. Lubricant Specifications
All moving parts in the winch are permanently lubricated at the time of
assembly. Under normal conditions factory lubrication will suffice. If
re-lubrication is necessary after repair or disassembly use Castrol Alpha
Spheerol L-EP 2 grease, 150 Viscosity (cSt) at 40∘

The length of power lead are subject to the distance less than 30 meters.
The length of switch lead are subject to the distance less than 3 meters.
For any other cases, the lead should use a bigger section or adopt a magnetic switch.
