Course detail
Equipment for Vertical Transport
FSI-QVD Acad. year: 2016/2017 Summer semester
The course of Means of vertical transport makes students acquainted with the fundamental principles of lifts and escalators designing and safety regulations for their operation. The course is concerned with the following topics: The development of the vertical transport. The division of lifts according to the drive type. The theory of traction drive: specific pressure and friction ratios in the groove of hoisting sheave. Structural elements: cage, cage guides, safety gears, etc. Escalators and moving footpaths. Principal parts of machines and their dimensioning. Driving and tension units. Safety elements. Examples of lifts, escalators and moving footpaths applications at unique construction works in the world.

Learning outcomes of the course unit
The acquired knowledge enables students to solve structural problems of personal and cargo transport in horizontal direction and mainly vertical direction. Students will learn regulations for both ways of transport. After the completion of the course students will be able to solve practical problems in a way of a diploma thesis or later in their professions.
Prerequisites
Students are reguired to have basic knowledge of technical mechanics, physics, higher mathematics, machine parts and their mechanism, physics of materials and principles of electrotechnical engineering.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Part of the course can be excursions to the companies, which manufacture or operate the equipments from the thematic area of education.
Assesment methods and criteria linked to learning outcomes
The course-unit credit reguirements the active attendance in seminars and passing the course test. Test is rated 100 points, for successful completion must get at least 50 points.
Aims
The aim of this course is make students familiar with the development of vertical transport, the transport of people and cargos especially in the vertical direction. Students will master the theory of fibre friction between the rope and the hoisting sheave. They learn of particular structural elements of hoisting lifts, hydraulic lifts, escalators and moving footpaths.
Specification of controlled education, way of implementation and compensation for absences
The attendance at seminars is obligatory, recorded by teacher. The form of compensation of missed lessons (in justified cases) is solved individually with the course superviser.
