Drum rotation, lateral loads and point of pull
Ok this helps. Thanks. What I learned: - winch location does not affect turning force in the drum but does affect bearing loads. - lateral loads on the pedestal increase exponentially with pedestal height so guiding the cable straight down the pedestal part of the distance to the drum will...- Powderbullet

Drum rotation, lateral loads and point of pull
Thanks. Maybe the attachments will help. My concern is lateral / side loading of the pedestal more than bearing loads on the drum itself. I have assumed that there would be an optimal height above the center line of a 24" drum to either mount the winch or a cable guide, but that is just...- Powderbullet

Drum rotation, lateral loads and point of pull
I farm and have built water control devices for my rice operation that use a cable and drum setup. The moving part is a 24"water tight rotary union that we rotate with a cable that originates in a dual spool winch above the center line of rotation for the drum. The winch cables secure to the...- Powderbullet
