A retractable sediment collection device for use in settling tanks is disclosed which has means for collecting and removing sediment from the floor of the settling tank. The retractable sediment collection device is structured to move back and forth along the floor of a tank to remove the sediment therefrom. The retractable sediment collection device includes a lifting mechanism which engages a sediment collector and raises it from the floor of the tank. Although the retractable sediment collection device is suitable for use in any kind of settling tank, it is particularly suited for use in closed tanks where access to the interior of the tank is limited through a single opening. The retractable sediment collector may be raised from floor of the tank to the top of the tank where the operating mechanisms can be accessed for repair or maintenance without removing the entire sediment collector from the tank.
