Postcard from the Summit – Azimuth Wrap

The massive set of cables going into the telescope must twist as the telescope rotates. Besides cables there are also hoses to carry high pressure oil, glycol coolant and compressed air. To accommodate the rotation, these cables and hoses go through a large assembly called the Azimuth Wrap. Looking a bit like an oversize bicycle chain with cable laced through the links, the wrap insures the cable does not kink, tangle or stretch as the telescope sweeps back and forth.

Lacing new cable through the wrap is an intricate task of threading through the metal comb that supports the cables in each link. See the little pink one in the middle, just did that…
