A DAMRAN type cable operated bar screen is used for large water flows. This machine is used particulary for removing medium and large coarse debris from a water inlet. This highly reliable machine can be used independently or in series side by side.
The raking mechanism consists of a trolley with nylon wheels which run in guides in the channel. The rake is in an open position when moving downwards.
At the bottom of the channel the rake closes and removes all debris from the coarse screen starting from the bottom up. At deck level the debris is removed from the rake by a scraper and discharged on a belt-conveyor, a concrete gutter or a container, as per clients wishes.
The Hubert mobile DAMRAN bar screen consists of a traverse carriage with a raking mechnism. The raking mechanism moves on rail tracks along (mutilple) bar screens, which it cleans section by section over the whole width of the intake channel.
The rake is able to handle small spacing’s (less than 30 mm) and deep channels. This type cleans the coarse screen in the upwards stroke (by winding the cable system) when the teeth are positioned between the bars of the screen and can be forced with the cable, resulting in optimal cleaning. Orientation of the screen can be almost 90°.
The mobile DAMRAN can also be fitted with a control platform or cabin with a control panel and a debris hopper.
