This 4th semester master project concerns the design of a support system for hydraulic rescue tools used by firemen to free persons trapped in cars in automotive accidents. The research and analysis phase contributes to the foundation of the project through the use of situated interviews, observing drills, analyzing theoretical training manuals and DVDs etc. On the basis of the research and analysis, a problem is stated: How are the tools supported and procedures improved resulting in higher performance, more precision and less physical strain? In the concept generation phase, a concept based on integration of known proven technologies is formulated on the basis of a sketching workshop and further investigations. The concept evolves in the concept development phase by the use of sketching in combination with 1:1 working models that validate and explore design proposals through and empirical approach. The concept is detailed and documented by means of 3D modeling. As a result, Hydra - Hydraulic Tool Support System is presented. A support system that through a harness in combination with a load-bearing arm relieves the operator of physical stress. With Hydra, the operator is able to work faster, more precise and with more endurance.
