Railway crane for cross-railway operation on a high-speed line

摘要

The invention relates to a railroad crane for cross-track operation on a high-speed line belonging to the field of cranes, and more particularly to a crane used on high-speed lines transported on the rails. Transverse mechanisms are arranged on outriggers and are connected to the crane via auxiliary supports; Lifting cylinders of the auxiliary supports lift the crane from its original track, after which the cross travel mechanism moves to a central area between the two tracks. The auxiliary supports retract to cause two sets of cross travel mechanisms to move to the center of the crane along with the support trucks until the auxiliary supports fully retract. The crane extends four crane supports and arranges balls from lifting cylinders of the crane supports in ball joint pans, which are arranged on the longitudinal beams of the support carriages; this distributes the force exerted on the original single track to the two tracks, achieves cross-track suspension on a high-speed line, and meets the safety requirements for large tonnages hanging on track bodies and bridge floors of an elevated high-speed line bridge section.
