Abstract:
1. An extendable cable tray assembly for retractable attachment to a section of a mast of a drilling rig comprising: an upper tray connected to the mast in stationary relationship; a center tray having a pivot end pivotally connected to the mast, and having an articulating end rotatable between a stowed position above the pivot end, and a deployed position below the pivot end; the center tray positioned in offset relationship to the upper tray; a lower tray having an upper end and a lower end; the upper end of the lower tray being pivotally connected to the articulating end of the center tray; the lower tray positioned in offset relationship to the center tray; an actuator, pivotally connected between the mast and the center tray; wherein retraction of the actuator results in retraction of the cable tray assembly to position the center tray substantially adjacent to the upper tray and adjacent the mast, and the lower tray substantially adjacent to the center tray and adjacent the mast; and, wherein extension of the actuator results in deployment of the cable tray assembly to position the center tray substantially below and offset to the upper tray and the lower tray substantially below and offset to the center tray.
