3.2 Performance Test
Confirm via load testing that the LL actuates within approximately +/- 8% of its setting.
4.0 Adjustment
4.1 General:
The general sequence for adjusting is to determine the Static Set Load (SSL), then use the SSL to adjust the Load
Limiter (LL).
4.2 Determine Static Set Load
4.2.1 General
The general formula for determining the SSL is
SSL = RC X SP X f
Where
RC is Rated Capacity of either LL or hoist. (see sections 4.2.2 or 4.2.3)
SP is the percentage of the hoist’s rated capacity at which the LL is to actuate (Factory set at
1.15%)
if is the Dynamic Load Factor to account for small load increases due to acceleration while
lifting.
4.2.2 Prior to Load Limiter installation:
If the LL is to be adjusted prior to installation on the hoist, then determine SSL using f and the LL’s RC from
Table 4-1.
