Course detail
Technology of Operating with Earthwork Machines
FSI-NT0 Acad. year: 2020/2021 Winter semester
The course introduces with the rock properties and classification by the exploitability, with the methods of the soil disintegration and proper usage of the individual earthwork machines according to the earthwork type and extent of the earthwork. The course introduces the operating systems and the control elements of the earthwork machines. This course is obligatory for the students applying for the earthwork machines driving licence.
