Technology of Operating with Earthwork Machines
FSI-NT0Acad. year: 2018/2019
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.
Learning outcomes of the course unit
Students will be able to consider earth properties and use suitable machines and technologies for their disintegration and manipulation. They will be also able to operate and service earthwork machines according to safety precautions.
Students are required to have basic knowledge of physics, machine parts and their mechanism and physics of materials.
