1000 - 10000mm Mechanical Bar Screen Wire Rope Bar Screen Wastewater Treatment

Wire Rope Bar Screen
Product Overview

The Wire Rope Rake Screen is a large-channel automatic cleaning device driven by a winch and steel wire rope. It moves a rake bucket up and down to remove floating debris, suspended solids, and large wastes from channels.
With a robust structure and strong cleaning capacity, it is ideal for large-flow, deep-channel, and coarse screening conditions in pumping stations and water intake facilities.

Working Principle

The system consists of a winch, motor, wire rope, rake bucket, bar screen, and control cabinet.
During operation, the motor drives the winch to move the rake bucket along guide rails.
The rake descends to capture debris underwater, then rises to discharge collected waste into a conveyor or bin at the top.
The operation can be fully automatic, triggered by water level difference or time settings.

Main Components

• Main Frame: Stainless steel or carbon steel structure with high tensile strength and corrosion resistance.

• Bar Screen: Customizable spacing for high interception efficiency.

• Rake Bucket: Captures and lifts debris effectively.

• Wire Rope & Winch System: Drives the rake’s vertical movement with high reliability.

• Drive Unit: Motor with reducer, equipped with limit switch and overload protection.

• Control System: PLC-based automation, manual/auto modes, and remote monitoring.

Features
