This mechanical Bar Screen utilizes large screenings rake / bucket, pulled by high-strength steel cables or Kevlar straps, for efficient removal of larger problem-causing debris, protecting valves, pumps and other downstream equipment from damage.
The PRO-Guard Cable Rake is typically installed directly in a concrete trough in a straight, upright vertical position making it suitable for confined spaces and / or wide deep channel lift stations. All moving equipment is kept above water, including drive equipment. This makes the equipment readily assessable for both inspection and maintenance. The GT-CS is operator friendly and allows the operator the freedom of controlling operating cycles manually, by a timer or based on hydraulic head loss utilizing water level detectors. The GT-CS Cable Bucket Rake Bar Screen is solidly designed and manufactured for easy maintenance and long service life delivery.
Untreated waste or storm water is received from the upstream side of the Bar Screen. A pivoting rake / trash bucket is lowered to the channel bottom by gravity, on tracks, by special high-strength steel cables or Kevlar straps and drum drive. The gravity lowered rake / trash bucket, the only mechanical part actually entering wastewater, pivots to scoop debris and engage the rake. It is then raised upward by a cable driven drive. When the rake / trash bucket reaches the operating floor; a wiper assembly is activated which ejects the retrieved material through a discharge chute for further handling.
