7.2 ANNUAL INSPECTION
At least annually, and more frequently if subjected to harsh conditions or excessive use, the winch MUST BE given a
detailed inspection by a competent person as described below, and the results recorded in an Inspection Log. A sample
Inspection Log is provided on Pages 24 & 23 of this manual, please make photocopies of this sample to record all inspection
results.
Determining Service Life Intervals of the Pro Series Safety Winch. The following calculations are based on the MANUAL
crank operation of the winch.
Three (3) revolutions of the crank hub drive =±1 ft (0.3m) cable
payout. Ten (10) revolutions of the crank hub drive = ±3 ft (1m)
cable payout. The cable payout is averaged and depends on
remaining cable left on spool/drum. If possible, a travel distance
should be estimated and recorded along with the Number of
travels (1 up/ 1 down, etc.) in the log book (located at the back of
the Pro series safety winch manual Rev07 (Pg. 25).
E.g.: A worker entering a ±32.8 ft (10m) pit 2 times daily will
travel (on average);
32.8 ft (10m) down + 32.8 ft (10m) up+32.8 ft (10m) down+ 32.8
ft (10m) up = 131.2 ft (40m) of travel daily.
131.0 ft (40m) x 3 (revolutions pre-cranks hub drive per 1 ft) = ±393.7 revolutions of the crank hub drive for a 131.0 ft use,
or 40m x 10 (revolutions pre-cranks hub drive per 1m) = ±400 revolutions of the crank hub drive for a 40m use
The Service interval of the Pro Series Safety Winch is based on 120,000
revolutions of the crank hub drive
or 5 years,
although maintenance and inspections should be carried out at regular interval as specified by customer policy and/or local
requirements to ensure the winch remains in proper working condition.
NOTE: Any time a winch is returned to a factory authorized service center for repair, please provide photocopies of all
previous Inspection Log sheets for that winch to assist with diagnosis and processing of any warranty claims.
Please obtain a Returned Goods Authorization number from the service center before sending your winch for service.

solvents or other chemicals to clean the winch.
