Abstract

The invention relates to a maintenance gantry crane, in particular to a large gantry crane. A hoisting mechanism and a working trolley operating mechanism are respectively arranged on a left side lower cross beam and a right side lower cross beam, so that the stress situation of a main beam can be improved, the structure is simplified, and the self weight of the main beam can be lightened. Meanwhile, due to the arrangement form of the large gantry crane, the maintenance and the overhauling of the hoisting mechanism and the working trolley operating mechanism can be more convenient, the situation that the maintenance and the overhauling personnel need to stand on the main beam to maintain and overhaul when the traditional maintenance gantry crane is in use can be avoided, and a ladder and a platform which are used for maintenance and overhauling can be omitted.
