ABSTRACT:
An apparatus for lowering articles from a building including a tower having a boom extending therefrom. A transfer carriage is slideably mounted on the boom and has a latching mechanism for engagement with an end plate on the boom. The carriage also has a mechanism for engaging a cage as the cage is raised by a cable to the carriage and disengaging the cage when the cage reaches the outer end of the boom. A cable mechanism in cooperation with powered drum members lowers and raises the cage while alternately raising and lowering a second cage which is on a boom with a transfer carriage identical to the first mentioned boom and transfer carriage. The rate of movement of the cable and therefore the rate of travel of the cages is controlled by a hydraulic motor connected to a closed loop conduit, the conduit having an orifice preset to regulate the flow of oil to and from the motor which in turn regulates the speed of the cable drums.
