PREVENTIVE MAINTENANCE
A regular program of preventive maintenance for your plan-
etary hoist is required to minimize the need for emergency
servicing and promote safe, reliable hoist operation.
The user of Braden hoist products is responsible for hoist
inspection, testing, operator training and maintenance
noted below with frequency dependent upon the severity
of the hoist duty cycle and the thoroughness of the pre-
ventive maintenance program.
Field experience, supported by engineering tests, indicate
the three service procedures listed below are the most
critical to safe, reliable hoist operation and MUST be ob-
served.
• Regular Gear Oil Changes (see notes 1 and 2 below
and page 15 of this manual)
• Use of Proper Gear Oil – recommended type for pre-
vailing ambient temperatures and additives (see page
15 and 16)
• Periodic Disassembly and Inspection of All Wear Com-
ponents – in compliance with ANSI specifi cation B30.5,
and API 2C and RP 2D.
1. The air motor case oil should be drained and refi lled
with recommended oil after 25 hours initial running and
every 200 hours thereafter or sooner if necessary; for
example, if the oil is contaminated by water in the air
line.
2. The winch gear oil should be changed after the fi rst
100 hours of operation or 30 days. The regular gear
oil change intervals may be adopted after the fi rst oil
change.
3. The proper oil level in the motor casing (at level plug
on page 16), must be maintained. The frequency of
replenishment will depend on the application and us-
age.
4. The air line fi lter should be drained at least once each
work shift and examined for clogging of the element.
Moisture in the air line that enters the motor will cause
accelerated motor wear. Moisture traps and air receiv-
ers in the air system will help minimize moisture in the
air reaching the motor.
5. The air line lubricator should be replenished as required
and set to give 6 to 8 drops per minute. If operation is
intermittent, double the rate to 12 to 16 drops per min-
ute.
Pre-use Inspection (each shift the hoist is used): This
inspection must be performed prior to placing the crane
into service and then as necessary during the day for ex-
tended operation.
1. Check for external oil leaks and repair as necessary.
This is extremely important due to the accelerated
wear that can be caused by insuffi cient lubricating oil in
the hoist. The winch drum gear oil level must be main-
tained between the maximum and minimum levels. The
oil level should be visible in the lower half of the sight
glass or level with the oil level plug on units without
a sight glass. Use only recommended lubricants. See
Recommended Lubricants chart in this manual. The air
motor oil level should be at the level plug.
2. Check air plumbing for damage, such as chafed or de-
teriorating hoses and repair as necessary.
3. Visually inspect for loose or missing bolts, pins, keep-
ers or cotter pins and replace or tighten as necessary.
4. Inspect the full length of wire rope, rigging and all
sheaves according to the wire rope rigging, and crane
manufacturer’s recommendations.
5. A warm-up procedure is recommended at each start-
up and is mandatory at ambient temperatures below
+40°F (4°C). The hoist should be operated at low
speeds, hoisting and lowering with no load, several
times to circulate lubricant through the planetary gear
sets.
Failure to use the proper type and viscosity of plane-
tary gear oil may contribute to intermittent brake clutch
slippage which could result in severe personal injury,
death, or property damage.
