Urbanization has been changing face of our cities for quite some time. This process is set to continue for the foreseeable future. Escalators and moving walks (MWs) are important integrants of today's infrastructure. They play an essential role in the mass transportation of passengers in airports, metro stations and other public places. This role is continuously increasing with the growth in public-transit systems around the world. In recent years, many new technologies have promised an advanced standard for escalator efficiency, energy savings, safety and comfort.
This new book provides the reader with an abundance of practical information related to escalator design and engineering. It includes information on the latest technology, specification and equipment available in the market, and is segmented into chapters consisting of:
This book is organized into four chapters. In Chapter 1, types of vertical transportation are introduced. A brief history of elevators, escalators and skyscrapers is given, and a general description of escalators follows. In Chapter 2, engineering of escalator components and certain principals of mechanics related to escalator design are presented in depth. Chapter 3 is devoted to special escalators like spiral, heavy duty, outdoor and helical. In Chapter 4, design of moving walks, similar to escalators, is discussed. At the end of the book, in the Appendix, some useful tables regarding definitions, formulae in metric, types of steel, truss bridges and methods of determining center of gravity/centroid are presented.
Throughout the book, the reader will notice many optional sections. These are indicated by an icon and may thus be easily distinguished from those that form the core of the book. They are mostly principals of mechanics and may be omitted if the reader is familiar with the subject without prejudicing the understanding of the rest of the text. Among the topics covered in these optional sections are truss structure, mechanics, vectors, statics of particles and rigid bodies.
