Abstract

Bachelor's thesis deals on construction of crane. There are four alternatives. There are options for power from the burdensome load 350 kg or 125 kg and each of these variations is further divided according the imposition of a crane. In all cases is used a similar structure, which differ only through the imposition of a crane. The work contains a static calculation, which solves the size of active forces in the designated points, then the resulting response and overturning moment in the deposit. Another filling is the calculation, where for example assesses the tap connection to the arm pillar, then weld joints, chain and ultimately shoulder for props. To achieve completeness of the award, bachelor thesis also contains an economic point of view, assessment of welding technology etc.
