The actual load factor to be chosen depends on the nature of the work and the kind of crane.
A dock-side crane unloading cargo with high lifts following one another in rapid succession will require a higher load factor than a workshop traveller with a very short lift and only a very occasional maximum load; and a traveller with a very long longitudinal travel will require a higher load factor for the travelling motor than for the lifting motor.
In practice, the load factor for electric crane motors varies from 3 to s.
The total power developed is 600 H.P., and though the load factor varies very greatly in this case, the differential type of governor used secures perfect control of the running of the wheels.
Interestingly, using chaining means that a hashtable can have a load factor that exceeds 100% .
