摘要
Collection unit, in particular a crust shovel designed to clean the anode holes, including a mobile vertical mast actuated by a first actuator, a frame fixed onto said mobile vertical mast and at least one articulated bucket, characterized in that said first actuator is at least one hydraulic jack fed by an hydraulic system arranged so that, at least when a second actuator actuates said bucket, the oil pressure in the chamber on the rod side is maintained at a substantially constant value making it possible to support a load corresponding to the weight of said collection unit, less a load of predetermined value, preferably lower than 1000 daN, and typically ranging between 200 and 600 daN. Advantageously, the portion of circuit feeding said chamber on the rod side is provided with a pressure regulator. With such a device, the debris may be collected by scraping the bottom of the cell without damaging it.
