On a monthly basis, pump a quality bearing grease (8 to 10
pumps) through each grease zerks.Routinely pumping grease
into the bushings acts to replenish the lubricant as well as flush
out any contaminants.Depending on the amount of usage and
the environment, this process
may need to be repeated during
theoperationcycle.

5.9. AutoDrumBrake
The automatic drum is actuated by a pneumatic cylinder.This
cylinder contains a compression spring that applies (retracts the
rod) the brake band and air pressure delivered to the cylinder
releasesbrake(extendstherod).Theairlinetothebrakecylinder
is plumbed with in via a quick exhaust valve.
This valve quickly
exhausts the air cylinder and allows the brake to set quickly.
Routinely inspect the quick exhaust valve to ensure that it is
working properly and that the exhaust port does not become
restrictedtherebycausingthebrakestosetslowly.
As the brake contacts directly on the
brake surface of the winch
drum it is susceptible to contaminants such as rust, dirt and oils
thatmaygetonthebrakingsurfaceandbecomeimbeddedinthe
friction lining of the brake bands.The brake linings and brake
surfaceshouldbeinspectedandcleanedroutinely.
As this is a
friction based brake, the friction lining needs to
inspected regularly for excessive wear.If any portion of the
frictionliningmeasures1/16”thickorless,thebrakebandsneed
tobere‐lined orreplaced.As the friction liningwears,thebrake
linkage will need to be tightened so as
to maintain its ability to
