| Summary |
|---|
In the course, students are deepened knowledge of theory, practical applications and design solutions of transport equipment. The course is devoted to the areas of theoretical foundations of transport, transport equipment for continuous transport, transport equipment for intermittent transport.
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.
1) Choice of type of transport equipment according to criteria, typical applications, economic aspect of choice, initial literature.
2) Conveyors with traction and support element, coefficient of friction, basics of force transmission, multi-drum drives, partial drives, belt construction, drive and tensioning stations, transient modes.
3) Special belt conveyors, conveyors with cover belt, closed, copying the terrain, new types and designs, eg Flexowel, Sicon.
4) Chain conveyors, construction, applications, deployment options, drive design and tensioning, calculation.
5) Articulated conveyors, construction, applications, application possibilities, construction of drive and tensioning, calculation.
6) Redlers, calculation, construction, applications, construction of carriers, drive and tensioning.
7) Overhead conveyors, construction of typical hinges, applications, construction of drive and tensioning station.
8) Bucket elevators, drive stations, tensioning stations, attachment of the bucket to the carrier, technological applications.

| Learning Outcomes of the Course Unit |
|---|
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.
