We have experienced many problems with free fall arrestors. Cables become loose and hang up causing freying of the cable and eventual cable breaks. I have heard that there is some sort of mechanism for keeping the cables on a free fall arrestor system from becoming loose and blowing in the breeze. Does anyone have any details about this?

You can use sway breakers ……..
· Cable can become wrapped around beans in high winds not allowing drill to go up or down.
· Have new simple sway-breaker design from Jeremy Krauthammer at the Hovensa DCU. He uses a rubber guide to hold cables in place, made from used conveyor belts. These are placed at about three locations along the steel structure where the cables are located.

The same rubber sway breaker design was installed at the Petrozuata Upgrader in Venezuela and the guys there tell me it works great.

We have a 6 coker operation in part of our facility and have sway breakers on the newest two. They have worked very well, while we have experienced hang-ups and issues with the other four. We are now proceeding with install on the remaining.

Welcome to the coking.com forum.
Please keep us updated on the sway breaker operation.
One question: What grease do you use in the cable grippers ?
