ABSTRACT:
An extractor carriage is furnished on each side with an elbow bracket projecting towards its lower portion. To each of these brackets is attached the end of a cable which moves the carriage in its forward direction towards the centrifuging machine. Each cable is protected at its upper portion from sand debris by lateral wings extending from the upper portions of a trough which receives the debris. These cables, as well as a third cable for returning the carriage, are wound around a single motor drum driven by hydraulic motors which are capable of operating at several speeds. The invention may be applied to centrifuging equipment for cast iron pipe.
