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

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

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

There are various types of mechanical gratings, generally comprising intercepting gratings for pollutants, toothed rakes for removing pollutants from the gratings, traction components for driving the rakes, and transmission devices, etc.

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