Hybrid Reels

Posted on Monday, December 9, 2013 in UEA Blog

If you, like virtually everyone else in the world, have at some time experienced the need to fit 'two ton of fertilizer in a one ton truck' then you may appreciate a hybrid reel that UEA has built for a few customers with limited available mounting space.   In these instances a cable reel and a hose reel have been combined into a single reel package which includes both a slip ring, for the electrical signal and/or power circuits, and a single passage fluid swivel.  The fluid swivel, with capacities up to 1.0” NPT, can be built for air or water pressures up to 250 psi, hydraulic oil up to 2000 psi and grease pressures up to 4000 psi.   On the electrical side of the reel the versatile UEA slip ring can be built to provide anything from low level communication circuits up to circuits rated to 600 amps at 600 VAC with combinations of voltage and amperage circuits available in one slip ring assembly.

Combination reels are available with either spring retract or as chain driven motorized with the motors offered in 12 or 24 VDC, 120 VAC, pneumatic or hydraulic versions.  These reels are limited to an application requiring basically the same extension length for the hose and the electrical cable or cables.  The hose and cable must be strapped together to provide even winding of the hose and cable during retraction. R91L6A1BH1

The reference photo includes a bottom-wind spring retract 9000 series reel with 30' of ½” air hose and 4/0 single conductor welding cable for extension.   The single conductor slip ring is rated for up to 60 amps for the intermittent duty of an arc welding application.  Note that although the fluid swivel is limited to a single passage the slip ring can be built to have more than one cable attached and bundled with the fluid hose similar to UEA cable reels with two or more cables bundled together.   The need for more than one cable could be due to a requirement to shield circuits from paralleling cables or possibly to provide circuits of different wire gauges and current ratings where the correct hybrid single cable is not readily available.

UEA combination reels may not solve all space restricted reeling problems but can be a possible option for some applications.
