Chapter 3: Power Supply Concepts for Driverless Industrial Trucks

Although relatively unknown some years ago, driverless industrial trucks have come to occupy an important position within the framework of highly organized systems of driverless transport (DTS). The essential factors contributing to this fact are without doubt on the one hand the increased need for automation in industry, and on the other hand the high degree of flexibility afforded by these appliances. | 3 Power Supply Concepts for Driverless Industrial Trucks P. PREUSS 3.1 THE IMPORTANCE OF DRIVERLESS INDUSTRIAL TRUCKS Although relatively unknown some years ago driverless industrial trucks have come to occupy an important position within the framework of highly organized systems of driverless transport DTS . The essential factors contributing to this fact are without doubt on the one hand the increased need for automation in industry and on the other hand the high degree of flexibility afforded by these appliances. The overall view of these appliances Figure 3.1 clearly shows that driverless industrial trucks DIT may as a whole be divided into three categories. The majority of these installations will be found in the automotive industry which requires a wide variety of applications specific to driverless trucks. In this context considerable importance will be attached to the third generation of driverless transport systems used for example to create the link between individual pieces of manufacturing equipment or assembly workplaces. This task may be designated product engineering transport and represents the second transport assignment after works transport to be mastered successfully by driverless industrial trucks. A third transport assignment transport between factories has so far been little investigated but is becoming more and more the subject of discussion. 119 Copyright 2003 by Expert Verlag.
