Hydraulic excavators work using Pascal's law where pressure applied in a confined fluid is transmitted equally in all directions, allowing the boom, bucket, and arm to lift and move material during digging
We DOPRO use only high quality low materials to produce superior product and all the manufacturing process such as heat treatment, forging, machining, grinding and ets, are strictly controlled by qualitied and experienced engineers in our factory with computerized and latest facilities.
All parts are thoroughly inspected at every time that each process such as cutting, heat treatment, machining, grinding, cleaning, assembly, etc. is carried out, and all inspection data per each production lot are maintained and controlled so as to be utilized as data for better qualities and performance improvement.
