if someone could help i would appreciate it. I have 2 cranes on the same runway, runway is roughly 700 ft. There is one disconnect at the beginning and there is an isolation point about 2/3 of the way down with another disconnect that shuts off the hotrail on one side of the isolation point off. My question is, Does this runway hotrail need 3 disconnects on the hotrail system???? And can someone tell me where can i find this information at? thanks
