Paccar Braden PD12C - Preventive Maintenance; Oil Level; Oil Change Procedure

12
A regular program of preventive maintenance for your
planetary hoist is strongly recommended to minimize the
need for emergency servicing and promote safe, reliable
hoist operation.
Field experience, supported by engineering tests, indicate
the three (3) service procedures listed below are the
MOST critical to safe, reliable hoist operation and must
be observed.
• Regular Gear Oil Changes
• Use of Proper Gear Oil – recommended type for
prevailing ambient temperature
• Periodic disassembly and inspection of all wear items.
The following minimum service intervals are specied
for operating hours of the prime mover.
1. OIL LEVEL
Check for external oil leaks and repair as necessary. This
is extremely important due to accelerated wear that will
result from insu󰀩cient lubrication. For hoists with a sight
glass, ensure that the sight glass is clear and functional,
then visually check oil level daily. For hoists without a sight
glass, check oil level monthly if no external oil leaks are
detected. Lubricant level must be maintained between the
minimum and maximum levels, midway up the sight glass
or at the bottom of the level plug port as equipped. Use
only the recommended type of lubricant.
PREVENTIVE MAINTENANCE
2. OIL CHANGE PROCEDURE
Gear oil should be changed after 100 hours of use for
new installation of the hoist to remove initial wear par-
ticles from normal break-in of the hoist. A minimum oil
change interval of one year is required. Refer to BRADEN
Technical Document LIT2739 (PB308) Inspection, Main-
tenance, Testing and Special Operating Instructions for
BRADEN Planetary Hoists for best practice for onshore
hoisting and additional requirements for personnel han-
dling or o󰀨shore lifting operations. The gear oil must be
changed to remove wear particles which impede the reli-
able and safe operation of the brake clutch and erode
bearings, gears and seals. Failure to change gear oil at
these suggested minimum intervals may contribute to in-
termittent brake slippage which could result in property
damage, severe personal injury or death.
The gear oil should also be changed whenever the
ambient temperature changes signicantly and an oil from
a di󰀨erent temperature range would be more appropriate.
Oil viscosity with regard to ambient temperature is critical
to reliable brake clutch operation. Our tests indicate
excessively heavy or thick gear oil may contribute to
intermittent brake clutch slippage. Make certain the gear
oil viscosity used in your hoist is correct for your prevailing
ambient temperature. Failure to use the proper type and
viscosity of planetary gear oil may contribute to brake
clutch slippage which could result in property damage,
severe personal injury or death. Refer to “Recommended
Planetary Gear Oil” for additional information.
3. VENT PLUG
The vent plug is located in the drum support as shown.
It is important to keep this vent clean and unobstructed.
Whenever gear oil is changed, remove vent plug, clean in
solvent and reinstall.
Do not paint over the vent or replace with a solid plug
or grease tting.
4. HYDRAULIC SYSTEM
The original lter element should be replaced after the
rst fty (50) hours of operation, then every 500 operating
hours or three (3) months, or in accordance with the
equipment manufacturer’s recommendations.
5. WIRE ROPE
Inspect entire length of wire rope according to wire rope
manufacturers recommendations.
6. MOUNTING BOLTS
Tighten all hoist base mounting bolts to recommended
torque after the rst one hundred (100) hours of operation,
then every 1000 operating hours or six (6) months,
whichever occurs rst.
