Crab of container gantry crane

This bachelor's thesis deals with design of crane trolleys, with a load capacity of 80 t and a lift height of 22 m. This crane trolley is constructed for a gantry crane used in a container transshipment yard. The gantry crane ensures the relocation and transfer of containers to means of transport. In this work, one specific type of a crane cat with two lifting drums and four travel wheels is calculated. The work is divided into three main parts. The first is a brief search of lifting devices. The second part is computational. The last part is focused on assembly drawings and welding of the main frame
