2) steel wire rope spooling length be more than 30m, be less than 50m when, duplex type hoist engine holding slowly at the uniform velocity accelerate, make wire rope roll around
When length is equal to 50m, v=V ensures that governor tripping speed acquisition is accurate；
3) when steel wire rope spooling length is more than 50m, duplex type hoist engine remains a constant speed decelerations, makes steel wire rope spooling length equal to 70m
When, v=0 ensures the lifting power for having time enough acquisition limiter of speed.
