Pre-Use Inspection:
(At the beginning of each shift the hoist is in use)
These procedures MUST be performed prior to placing
the crane or vehicle into service, and then as necessary
during extended operation. This inspection must be per-
formed by a qualified crane operator or qualified crane
inspector.
1. Check for external oil leaks and repair as needed.
This is extremely important due to the accelerat-
ed wear that will result from insufficient lubricat-
ing oil in the hoist.
The gear lubricant level
MUST
be maintained at the proper level. The oil level
should be visible in the lower half of the sight glass.
Use only the recommended type of lubricant. Refer
to page 16 of this manual and Braden Service
Bulletin 503 (latest revision) for gear oil recommen-
dations.
2. Inspect the vent plug to ensure it is not clogged.
Clean in solvent and replace as needed.
3. Check the ratchet and pawl mechanism (if equipped)
for proper operation and for full engagement of the
pawl with the ratchet wheel. Repair or adjust as nec-
essary. Be sure to grease the pins and bushings at
this time.
4. Check the hydraulic plumbing for damage, such as
chafed or deteriorating hoses, and repair as neces-
sary.
5. Visually inspect for corroded, loose or missing bolts,
pins or other fasteners, and replace or tighten as
necessary.
6. Visually inspect rotation indicator sensors, anti-two
blocking switches and other safety equipment, and
repair as necessary.
7. Inspect the full length of wire rope, rigging and all
sheaves, according to the wire rope and vehicle or
crane manufacturer's recommendations.
8. A warm-up procedure is recommended at each start-
up, and is mandatory at ambient temperatures below
+40°F (+4°C). The vehicle engine should be run at
its lowest recommended idle RPM with the hoist
control in neutral allowing sufficient time to warm up
the hydraulic system. The hoist should then be oper-
ated at low speeds, hoisting and lowering under no
load, several times to prime all the hoist hydraulic
lines with warmed oil, and to circulate lubricant
through the planetary gear sets.
Quarterly Inspection:
Every three (3) months
, or monthly in Severe Duty
Application, or prior to placing the machine in service if
it has not been used for a period of 3 months or longer.
Documentation of the inspection records must be kept
with the hoist / crane for a minimum of two (2) years
from the date of inspection. This inspection must be car-
ried out by a qualified crane operator or qualified crane
inspector. A qualified crane inspector shall perform
inspections on cranes assigned a moderate, heavy or
severe usage category.
1. Perform
ALL
prior inspections (Pre-use inspection).
2. Hoists used in personnel handling applications
MUST
have the internal spring-applied brake tested
as defined on page 18 of this manual.
3. Hoists equipped with auxiliary brake assemblies
MUST
have the auxiliary brake tested as defined on
page 19 of this manual.
4. Inspect all fasteners for tightness and the presence
of corrosion. Replace ALL corroded fasteners and
tighten to the proper torque value for the fastener
size and type. (Refer to torque specifications on
page 11 of this manual.)
5. Inspect the hoist structural components (base, sup-
ports, drum, etc.) for corrosion and repair or replace
as required to maintain the structural integrity of the
hoist.
6. Change the hydraulic system filter(s). Hydraulic fil-
ters should be changed after the first 50 hours of
crane operation, then every 500 hours or quarterly,
or in accordance with the crane manufacturer's rec-
ommendations.
Semi-Annual Inspection:
Every six (6) months
, or quarterly in Severe Duty
Applications. Documentation of the inspection records

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.
