Course detail
Technology of Operating with Earthwork Machines
FSI-NT0 Acad. year: 2019/2020 Winter semester
The course makes students acquainted with rock properties and classification by the exploitability, with methods of soil disintegration and proper usage of individual earthwork machines according to the earthwork type and extent. Besides, it deals with operating systems and checking elements of earthwork machines. This course is obligatory for students applying for the earthwork machines driving licence.
