What tasks can scrapers accomplish?

A shovel loader is a type of soil transportation machinery that uses a shovel to cut soil and load the broken soil into the shovel for transportation. It can complete comprehensive operations such as digging, loading, transporting, unloading, layered filling, and local compaction, and is particularly suitable for leveling sites in railway, road, water conservancy, power and other engineering projects.

Scrapers have various advantages, including simple operation, no terrain restrictions, independent operation, fast driving speed, and high production efficiency. It is suitable for soil types one to three, but if it is necessary to excavate soil types three or more, pre loosening may be necessary.

The working principle of a scraper mainly utilizes the telescopic function of the hydraulic system. The hydraulic pump converts mechanical energy into hydraulic energy, compresses hydraulic oil, and sends it to the hydraulic cylinder. The piston of the hydraulic cylinder moves under the action of hydraulic oil, thereby pushing the bucket to perform operations such as digging, transporting, and unloading soil. The operator can change the variables of the hydraulic system and achieve various actions of the bucket by controlling the handle or foot pedal.
