Vändning av trafikelement : Konstruktion åt företaget Forshaga Svets & Smide

Sammanfattning: Stenteknik i Karlstad AB is a company that manufactures traffic elements. These traffic elements are currently turned 180 degrees by an overhead crane and are considered to be time consuming and unsafe. In order to make the process more efficiently and safer, Stenteknik i Karlstad AB has requested a construction that offer this. Forshaga Svets & Smide has been assigned this task and this master thesis will generate a solution for them. The objective of the project is to find a solution that safe and efficiently turns the elements and thereby improves the working environment, reduces the production costs and lead times. The solution will also be produced in CAD format which will then be handed over to Forshaga Svets & Smide. The project began with a pilot study to create an overview of the current situation and obtain information about the subject. A requirement specification, containing requirements for the construction, was created by the information produced from the pilot study together with the wishes made by Stenteknik i Karlstad AB. The requirement specification has been the basis for this project. Different concepts have been created through concept generation methods. The concepts developed have been modeled so that they can then be presented to the project supervisor who either elaborated, corrected or rejected them. The “Hinge” became the final concept that is not in need of either engine or hydraulics. The Hinge is a concept based on an overhead crane to turn the traffic elements. With this concept the turning takes place in a safer and more efficient way than before. The project has followed the various stage of the product development process that have been studied during the program for Mechanical Engineering. Approximately 600 working hours have been spent on this project.
