  • Publication number: 20170349419
    Abstract: The present invention relates to a gantry tower crane for inspecting a cargo hold, comprising: two running rails which are installed to be spaced apart from each other in the longitudinal direction of the cargo hold; two prefabricated towers, each of which are installed to be able to move along respective running rails; and a basket which is installed to be able to move up and down along the prefabricated towers. Thus, as the basket installed in the prefabricated towers is installed to have a variable length and to be rotatable, it is possible to inspect both wall surfaces and a ceiling of the cargo hold, and to inspect the wall surfaces while moving along an overpass. Also, it is possible to obtain an effect of being able to perform inspection more precisely in a state where an operator comes closer to the wall surfaces by extending an auxiliary foothold of the overpass.
