Course detail

Equipment for Vertical Transport

FSI-QVDAcad. year: 2013/2014

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.

Co-requisites

Not applicable.

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.

Assesment methods and criteria linked to learning outcomes

The course-unit credit reguirements: the active attendance in seminars.
The exam: The exam verifies the knowledge of theory and structural design of lifts and escalators and consists of: 1. Written exam, 2. Oral exam

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.
