ULTRA-LIGHT TELESCOPIC CRANE/PLATFORM MECHANISMS FEATURE ANALYSIS

Based on the research of mechanical properties of fine-granular high-strength steels and the obtained results, the design of prototype ultra-light telescopic crane was performed. The article presents the analysis results of the crane drive mechanism. The geometric synthesis of shapes and sizes of four joint was performed based on the maximum and minimum slope of each arm and on the minimum weight. Feedback of optimal shape of each mechanism's stick was implemented by the variant solutions evaluation methods. The detailed calculation of stress and strain in each mechanism's stick was performed by finite elementmethod.
