Mechanical grates are a grate equipment capable of automatically removing debris attached to the grate.

Mechanical gratings are one of the early purification equipment developed in water and wastewater treatment technology.

It significantly reduces the labor intensity for workers, protects their physical health, minimizes water head loss, and enhances the efficiency of the pumping station.

A variety of mechanical gratings are available, typically including grates for intercepting pollutants, toothed rakes for removing intercepted pollutants from the grates, traction components to drive the rakes, and transmission devices.

Mechanical gratings can be divided into three main categories based on the position of the cleaning rake: front cleaning, rear cleaning, and self-cleaning.
