Konstruktion av lastväxlardumper enligt DIN 30722

Sammanfattning: Thise thesis for 15 credits/student were executed at Zetterbergs Industry AB in Östervåla by two students. Zetterbergs develops, manufactures and mount bodywork and components for transporting trucks. Their main focus is earthmovers in the nordic countries. Recently Zetterbergs released a new dumper for hooklifts called ZD4-LV. The company promote it as a lightweight dumper for hooklifts with an appealing design. The dumper for hooklifts is built after the swedish standard and Zetterbergs now wants to produce a dumper for hooklifts that follows the german standard, DIN 30722. In the beginning of the thesis a thorough examination of the two standards SS 3021 and DIN 30722. The company wanted the new dumper for hooklifts to use the same basket as ZD4 so the student examined how the ZD4-LV was designedconstructed and manufactured. To generate concepts the five-step method were used. To figure out the best concept Pugh’s matrix were used. The result is a complete CAD-model with associated manufacturing drawings of a complete dumper for hooklifts that follows DIN 30722. New models and drawings have been made for all the new parts and assemblies, but for the existing parts, it uses the existing drawingsexisting drawings will be used. The thesis is considered a success hence all set goals were met.
