Wire Rope Hoist

Regarding the Load-Time Factor and the Starting Frequency
In case of the Bando wire rope hoist is set, the Load-Time factor is 40% and the Starting Frequency is 240 times /hour for the repetitive operation.
Load-Time Factor = ((Total of the time when the motor is live with electricity in a severe working condition)/60 minutes)× 100
Starting Frequency = Starting frequency per hour in an severe working condition

Light load Light load Can be used for 8 hours per day 1m 1m 1m 2m 2m 3m 4m
Standard load Standard load Can be used for 4 hours per day 1m 1m 2m 2m 3m 4m 5m
Heavy load Heavy load Can be used for 1 hour per day 1m 2m 3m 4m 4m 5m 5m
The signs such as l m and ll m in the above table show the applicable ranges of the crane structural standard. The wire rope hoist can be used up to ll m
