CABLE SCREEN WITH 1 OR 2 CABLES

The cable screens designed by Dewekon Engineering consist of: 

• The frame is a welded plate-construction, calculated to resist the highest water level ahead of the screen.
• Guiding profiles to guide the scraper mechanism.
• The screen bars have a hydrodynamic section, to prevent the screen from clogging, and to create a minimum of hydraulic loss through the screen.
• A  backplate above the bars to bring out the screened waste.
• The scraper is lifted by one or two cables, depending on the width of the screen.
• The scraper is guided by 4 wear resistant wheels. They have a grease point.
• The drive unit is on top of the screen frame. It consists of the main driving shaft and one or two cable drums, driven by a motor gearbox.
• The drive unit is a hermetical closed oil-bath gearbox with brake motor.
• The scraper goes down in "open" position at a distance of 40cm from the screen surface.
• When the scraper arrives in the lower position it closes slowly. The speed of closing the scraper is adjustable.
• The teeth penetrate between the bars, and the screenings are moved upwards.
• The teeth of the scraper are replaceable.
• The positions at the top and bottom are detected by a limit switch, next to the gearbox.
• The movement downwards of the scraper is protected by a "slack rope detection".
• During the rise of the scraper the mechanism is protected by a torque limiter (option).
• The screen is equipped with all safety devices according to the European CE directive.
