The role of hydraulic presses in modernization construction.
Based on the mechanical drive excavator, a hydraulic excavator has been developed. Its working process involves cutting the soil into blocks using the cutting edge of the bucket, loading the soil into the bucket, lifting it, rotating to the dumping position, and then returning the emptied bucket to the excavation position to start the next cycle. Therefore, a hydraulic excavator is a cyclic earthmoving machine. Hydraulic excavators are widely used in industrial and civil construction, transportation with hydraulic motor drive systems, water conservancy projects, open-pit mining, and modern military engineering, serving as an indispensable important piece of machinery in various types of earthwork construction.
During construction, they can be used for excavating wet foundation pits, digging drainage ditches, demolishing old buildings, and leveling sites. By changing the working attachments, they can also be used for loading and unloading, installation, piling, and uprooting trees. In hydraulic engineering, plunger hydraulic traveling motors can be used for excavating reservoirs, canals, dam foundations for hydropower stations, drainage or irrigation ditches, and dredging and excavating original river courses.
In railway and highway construction, they are used for excavating and filling, constructing roadbeds, leveling the ground, and digging drainage ditches along road embankments.
