Custom Dock Crane Slip Ring

Posted on Friday, October 4, 2013 in UEA Blog

A new 70-circuit electrical slip ring giant has made its way through United Equipment Accessories.  The 85” tall slip ring was designed to be hanging upside down in a room inside a large dock crane.

Due to the amount of large circuits required, the slip ring was separated into three DockCraneSRsections.  The lower section was comprised of a combination of larger sized power circuits and some control circuits.   The center section was comprised of a combination of some medium sized power circuits and some smaller sized power circuits.  The upper section comprised of some signal circuits which had their own wrap around aluminum enclosure.

The three slip ring sections were attached to the custom steel mounting tube and retained inside the large painted steel enclosure using twelve laser cut brackets.  The custom painted steel enclosure housed slewing ring bearings on each end and lifting eye bolts.  The large slots machined into the steel mounting tube allow for easy wire access into the center and down through the tube.  The open frame design of the enclosure allow for easy wiring and visual inspection.

United Equipment Accessories continues to strive to make sure that each customer gets the features that they want for their slip ring assembly!
