In addition to having to work with resistance, the hand tool is often bounced by the force to rewind the wound orbit, resulting in injury to the operator.

On the other hand, according to the hydraulic track maintenance equipment of the present invention, after the closed track is connected to the clutch connecting shaft of the track winding, the one-way rotary clutch is wound in a state where the one-way rotary clutch is provided so that the phenomenon of the winding track to return to the one-way rotary clutch Not only can the work be done safely, but it also has the effect of completing all windings in as little as 15 minutes as a pair of workers.

In the bogie wheel extraction operation according to the related art, at least two working persons and a driver must consume a long time of 30 minutes or more, and after fixing it inclined using a separate steel strut, the steel strut is moved forward. When the track surface is positioned vertically by rotating the track surface, the extraction wheel is lifted by lifting the bogie as much as the difference in height, and in the process, the steel prop is broken by the weight of the vehicle. Safety accidents are often injured, but according to the hydraulic track maintenance equipment of the present invention, there is an effect that one operator can safely complete the work within 10 minutes.

 In addition, according to the hydraulic track maintenance equipment of the present invention, by using a radio controller, it is possible to operate the hydraulic track maintenance equipment at a distance of 70 ~ 80m, there is an effect that can safely protect the operator from safety accidents.
