Description

Lifting tool for laying subway rail Technical Field The utility model relates to the technical field of lifting tools, in particular to a lifting tool for paving a subway rail. Background As a more convenient railway transportation form, subways have been popularized in more and more cities. The subway track comprises a plurality of end-to-end track panels, wherein the track panels are an integral body mainly composed of two parallel steel rails and sleeper uniformly arranged below the steel rails. In the process of paving a subway rail, a hanger is required to be used for stably lifting the rail panel to a preset position; But current track handling instrument needs the manual work to link to each other handling instrument and subway track when carrying out hoist and mount, and is comparatively loaded down with trivial details when hoist and mount, at the in-process of hoist and mount simultaneously, makes the rail produce radial rocking easily, and then has the potential safety hazard that the track panel breaks away from the lifting hook, and for this reason, we propose a handling instrument for laying subway track.
