! WARNING !
Failure to properly warm up the hoist, particularly under low
ambient temperature conditions, may result in temporary brake
slippage due to high back pressures attempting to release the
brake, which could result in property damage, severe personal
injury or death.
PREVENTIVE MAINTENANCE
7. WARM-UP PROCEDURES
A warm-up procedure is recommended at each start-up
and is essential at ambient temperatures below +40°F
(4°C).
The prime mover should be run at its lowest recommended
RPM with the hydraulic hoist control valve in neutral
allowing su󰀩cient time to warm up the system. The hoist
should then be operated at low speeds, raise and lower,
several times to prime all lines with warm hydraulic oil, and
to circulate gear lubricant through the planetary gear sets.
8. INSPECTION
A. Bearings and Gears – Refer to HOIST
DISASSEMBLY, pages 19 and 20; and PLANET
CARRIER SERVICE, pages 30 and 31.
B. Brake Cylinder – Refer to MOTOR SUPPORT –
BRAKE CYLINDER SERVICE, pages 42 to 45.
C. Brake Clutch – Refer to BRAKE CLUTCH
SERVICE, pages 46 and 47.
9. RECOMMENDED PLANETARY GEAR OIL
The use of proper gear oil, in conjunction with employing
a preventative maintenance program, may extend the
life of your BRADEN planetary winch, hoist or drive while
ensuring safe and reliable operation.
The gear oils detailed on page 14 have been factory tested
to meet BRADEN specications within di󰀨erent ambient
temperature ranges. If these products are not available
in your area, an equivalent lubricant may perform equally
well, although it has not been factory tested to ensure
compatibility with BRADEN products.
