The invention relates to the technical field of railway beam changing, in particular to a crane and a beam changing machine. The crane comprises a rack used for being arranged below a main beam of the beam changing machine, a hoisting device, a longitudinal movement driving mechanism and a transverse movement driving mechanism, wherein the hoisting device, the longitudinal movement driving mechanism and the transverse movement driving mechanism are all arranged on the rack, the hoisting device walks in the transverse direction relative to the rack, the hoisting device, the longitudinal movement driving mechanism and the transverse movement driving mechanism are all arranged on the rack, and the longitudinal movement driving mechanism comprises a walking part used for being matched with the side edge and/or the bottom edge of the main beam of the beam changing machine and a driving assembly used for driving the walking part to move. According to the crane provided by the invention, by means of the arrangement of the longitudinal movement driving mechanism matched with the side surface of the main beam of the beam changing machine, the crane is effectively prevented from occupying the height space above the main beam of the beam changing machine, the height requirement of a railway limit is met without sacrificing the height of a supporting leg, and operations of simply-supported box beam changing and transporting frames are conveniently completed.

    本公开涉及铁路换梁技术领域,特别涉及一种起重机及换梁机。该起重机包括用于设置在换梁机主梁下方的机架、起吊装置、纵移驱动机构及横移驱动机构,起吊装置、纵移驱动机构及横移驱动机构均设置于机架上;起吊装置相对机架在横向上行走,起吊装置、纵移驱动机构及横移驱动机构均设置于机架上;纵移驱动机构包括用于与换梁机主梁的侧边和/或底边配合的行走部、用于驱动行走部运动的驱动组件。本公开提供的起重机中,通过设置与换梁机主梁的侧面配合的纵移驱动机构,有效避免起重机占用换梁机主梁上方的高度空间,不用牺牲支腿的高度来满足铁路限界的高度要求,便于完成简支箱梁换运架操作。
