Line Speed Monitor and Overspeed Alarm Installation
Not illustrated in Product Parts Information Manual.
1. The assembly bracket attaches to the motor mounting flange and is secured with
two capscrews (97).
2. Mount the line speed monitor to the bracket and secure using capscrews and
nuts.
3. Install the sensor to the bracket assembly and secure with lock nuts.
Testing
Operational Test
Prior to initial use, winches shall be tested to ensure proper operation. Prior to
initial use, all new, altered or repaired winches shall be tested to ensure proper
operation.
a.
Check oil level in motor, reduction gear assembly and disc brake are correct.
b.
To initially ‘break in’ new or overhauled motors operate without load, in
both directions, for 15 minutes at 100 - 200 RPM.
c.
New Drum Brake Band Lining Run-in Procedure: All new drum brake band
linings require a ‘run-in’ period.
d.
Operate the winch without load in the payout direction while gradually
applying the brake. Allow the brake to slip for approximately one
minute.Winch motor may stall as drum brake band lining fully engages. Do
not allow brake to overheat.
e.
Check operation of brakes. Adjust if necessary as described in the
“MAINTENANCE’ section.
f.
Check operation of limit switches, locking devices and all safety devices
when equipped.
g.
Check foundation mounting fasteners are secure.
h.
Install drum guard.
Load Test
Prior to initial use, all extensively repaired winches shall be load tested by or under
the direction of an
Ingersoll Rand
trained technician and a written report furnished
confirming the rating of winch. Test loads shall not be less than 100% of rated line
pull and should not exceed 125% of rated line pull. To test winch at 125% of rated
load apply following load with wire rope on the first layer of the drum:
1. To test the winch at 125% of the rated utility load of 3,500 lbs (1,558 kg) apply
the following load with the wire rope on the first layer of the drum:
FA2i-MRA Winch 4,375 lbs (1,985 kg)
NOTICE
• Testing to more than 125% of rated line pull may be required to comply with
standards and regulations set forth in areas outside of the USA.
Linespeed Indicator and Overspeed Alarm
During operational and load tests, observe winch line speed. Maximum allowed line
speed, when used as a
Man Rider®
, should not exceed 100 ft/min (30.5 m/min). The
visual overspeed alarm must activate when line speed reaches 100 ft/min (+/- 10 ft)
[30.5 m/min (+/- 3 m)].
Brakes
Test the drum automatic and manual band brakes independently. Each brake shall
hold 150% of rated load without slipping. Automatic drum band brake must stop and
hold test load when the winch throttle lever is placed in the neutral position. Manual
drum band brake must be able to stop and hold test load when the winch throttle
lever is placed in the neutral position and brake is applied.
Limit Switches
Operate winch in both directions to activate limit switches. Limit switches should
engage at established settings [+/- 2 feet (2/3 m)], and prevent winch operation
must reset after reversing winch operating direction and allowing drum to turn
approximately three full revolutions.
