Both ends of the main beam are respectively rigidly connected with the upper ends of brackets of the front road wheel group and the back road wheel group, and a cab, a power unit and a control cabinet are arranged above the lateral wheel group frames; the transporting and lifting system is arranged on the main beam. The lifter uses a set of devices to accomplish the works of stripping a hanging beam, lifting, carrying and laying a beam and loading the hanging beam, which are accomplished by three devices in the past, so the availability ratio of the devices is improved, and the total investment of construction equipment for a project is decreased. The utility model can not only simultaneously replace a plurality of large portal jib cranes, but also smartly change directions, move laterally and longitudinally and lift box beams.
