An excavator cannot function normally after being submerged in water. Below is relevant information about excavators: Excavator: An excavator, also known as excavating machinery or a digger, is an earthmoving machine that uses a bucket to dig materials above or below the machine's surface level and load them into transport vehicles or unload them at stockyards. The materials excavated by an excavator are mainly soil, coal, sand, and pre-loosened soil and rocks. From the perspective of recent developments in construction machinery, excavators have progressed relatively quickly and have become one of the most essential pieces of construction machinery in engineering projects. The three most important parameters of an excavator are operating weight (mass), engine power, and bucket capacity. Comparative differences: Loaders are typically seen at ports and logistics centers, mainly for loading and unloading containers. Graders are used for leveling roads, snow removal, bulldozing, loosening soil, and other functions. Excavators are a common type of construction machinery, primarily used for digging soil, loading trucks, demolition, ground breaking, and crushing rocks. Forklifts are mainly for shoveling soil, snow, and loading trucks, with a scope of application similar to excavators, but with limited working conditions and higher efficiency than excavators. Forklifts cannot operate in soft soil or steep ditches and are generally wheeled. Bulldozers are mainly used for pushing soil, leveling, and loosening, so it's common to see excavators and bulldozers working together in many development areas, with very high efficiency. Scrapers, as the name suggests, are for shoveling and transporting soil. Scrapers usually shovel soil in areas with abundant soil and carry it in their 'belly,' traveling up to 500 to 2000 meters to unload the soil where it is needed. Loaders are self-propelled loading machines that load bulk materials onto vehicles or other equipment. Loaders can also perform light digging tasks and, by changing the corresponding work attachments, can be used for bulldozing, lifting, and loading materials such as wood and steel pipes. Scrapers can be used as loaders, but loaders cannot be used as scrapers. Bulldozers are machines driven by tractors, equipped with a wide, blunt horizontal blade for clearing land, road construction, or similar tasks.
