The invention discloses a lifting trolley suitable for a large bridge crane, and belongs to the technical field of lifting machinery. The lifting trolley is characterized in that modularized processing is carried out on a hoisting mechanism, and a double-track form is adopted, thereby improving the stress of the main beam; the lifting trolley is reasonable in stress, quick to position, convenientto mount and convenient to realize modularized manufacture, and also greatly reduces the height and lightens the dead weight; modularization processing is carried out on a travelling mechanism trolley; the increase and decrease of hoisting mechanism modules are utilized, and a hoisting beam is quickly assembled, so that bridge cranes with different models and hoisting ranges can be flexibly assembled, the application range of the bridge cranes is expanded, and the production cost is decreased; meanwhile, no integral frame is arranged, and a mounting framework is formed by a connecting beam ofan overlapping running mechanism trolley module and a lifting beam of a hanging lifting mechanism module; and the lifting trolley is compact in structure, light in weight and large in mounting space.
