Elastomeric Tightly Meshed Trough Cover

[jdkuhndog]

Does anybody have any information/experience with covers for troughs?

I have an application with an overhead crane being powered by a 2" diameter cable coming off of a horizontally fed cable reel. The cable will be pulled by the crane and will lay in a trough mounted just to the side of the runway beam. The trough needs to be sealed after the cable is laid into the trough and after it is lifted up out of the trough (the cable is being lifted up and layed into the trough by simply reacting to where the crane is located).

I was thinking of using an elastomeric type cover which has a 'finger type' mesh to it - in that it would only open or close in the immediate vicinity where the cable was passing through. Should be a relatively solid seal/cover when closed.

Does this make sense? If not I can go into more detail.

Anyhow, is anybody familiar with a product out there that would suit this application. The trough will be approx. 8" wide & the material to cover the trough will need to be pretty resistant to gamma radiation.

Any help would be appreciated.

Thanks !
