Subject aims expressed by acquired skills and competences
During the course, students will deepen their theoretical knowledge of the construction of transport machines and the requirements for their safety. The overall completion of previous theoretical knowledge, about the whole and partial mechanisms of transport, handling and lifting equipment, will be extended by in-depth theoretical knowledge, as well as structural and practical knowledge. Students will acquire basic skills: technical thinking, creativity, communication and organizational skills.
The course deepens knowledge of transport, handling, lifting and process equipment. The system of purposefully selected information enables students to make independent creative inputs into field applications that are at a high level of innovation and lead many students to the registration of their first inventions. The aim of the course is to support students' creative abilities with deepening their ability to see the connections between the machine, material, operation, ergonomics and a complex of other connections.

Way of continuous check of knowledge in the course of semester
1. During the semester, the student takes 2 tests at seminars (each with a maximum of 10 points, a minimum of 5 points).
2. The student writes a year seminar work from the literature of an individually assigned topic in the field of transport machinery.
3. The student submits to the instructor in the credit week the seminar work prepared from the professional literature of an individually assigned topic in the field of transport machines and passes its elaboration to the instructor in electronic form in Word.
4. The seminar work, its content, scope and level will be defended by the student during the exam.
