What is the purpose of attaching a rope to the barrel-type strainer?

Attaching a rope to the barrel-type strainer serves primarily to aid in positioning the strainer in the water. This allows for greater control when placing it, ensuring that it is submerged adequately to draw water without drawing in debris or sediment that can hinder pump performance.

Using the rope in this manner is crucial during operations where water sources may be unpredictable, such as in firefighting scenarios involving rivers or lakes. The ability to maneuver the strainer easily can help maintain a stable water supply and improve the efficiency of water intake, which is vital during emergencies.

Utilizing a rope in this context also enables the fire personnel to quickly adjust the position of the strainer based on environmental conditions, ensuring optimal functionality and safety during operations.
