A cable tray assembly including a pulling mechanism is described herein. The cable tray assembly includes a tray member defining a predetermined path and mounted in the ceiling of a building to support a plurality of cables extending from a dedicated room to a plurality of workstations. The pulling mechanism includes a pulling rope defining a closed circuit and mounted to the tray member through pulleys for longitudinal movements along the predetermined path. The pulling rope is provided with a cable securing element to which cables to be installed from the dedicated room to the workstations may be attached. Longitudinal movements of the pulling rope along the predetermined path will therefore displace the cable securing element and the cables attached to it from the dedicated room towards the workstation.
