MAINTENANCE
Tulsa Model 1200W planetary winches, like any other pieces of machinery, need to be
periodically serviced and well maintained to insure their proper operation.
Good maintenance consists of three steps:
1.
A daily inspection to insure that there is no oil leaks present, that all mounting bolts and other
fasteners are tight, and that wire rope is in good condition.
2.
Periodic servicing of the winch including changing the oil in both the gearbox and the brake
section. Severity of use will determine the need for oil changes but it should be checked at a
minimum of every 500 operating hours and changed every 1000 operating hours. Factors
such as extremely dirty conditions or widely varying temperature changes may dictate even
more frequent servicing.
3.
Complete teardowns and component inspections. Again, severity and frequency of use will
determine how often this should be done. If the crane or other equipment, which this winch
is mounted on, is subject to standards for this type of inspection, then those standards must
be followed. If oil changes reveal significant metallic particles, then a teardown and
inspection must be made to determine the source of wear.
WIRE ROPE
Wire rope should be installed as shown in the drawing below. Note that the wedge will satisfy
cable diameters from 7/16" to 5/8", depending on how it is installed in the cable drum
