[0002] In railway engineering, track maintenance is an important part of ensuring safe railway operation. Tracks need to be lifted and repaired regularly to clean the ballast, monitor track wear and replace them. A track lifter is a small machine used in the maintenance of railway subgrades. Through manual operation, the track lifter can lift the rails a certain distance from the ground to facilitate workers to maintain the subgrade. The existing track lifter lacks an effective limiting mechanism after lifting the track, which causes the track to easily deviate, affecting maintenance efficiency and safety. Therefore, a track lifter for railway maintenance is proposed to overcome the above problems. Summary of the invention
