In an oil derrick separate service loops which are power cables and/or hydraulic hoses are affixed at one end to a top drive and affixed at an opposite end to an oil derrick end, adding a series of polyurethane supports or rungs along the length of the separate service loops to provide a little lateral motion but to limit the overall amount of lateral motion. The rungs will also help insure that the cables and hoses do not wrap themselves around everything when the wind blows. In order to carry the weight of the cables, two parallel steel cables are affixed on either side of the copper cables, and two steel cables are affixed on either side of the hydraulic hoses. These steel cables will be terminated at the derrick and the top drive by being affixed to steel brackets received in steel mounting plates all designed to withstand the loads.
