A track working machine comprises a machine frame extending in a longitudinal direction and having opposite ends, the machine frame having an upwardly recessed portion between the ends, and undercarriages supporting the machine frame ends on the track for mobility thereon in an operating direction. An operator's cab has an access below the upwardly recessed machine frame portion for permitting an operator to enter and leave the cab, and two structural parts are attached to the machine frame and extend in the longitudinal direction below the upwardly recessed machine frame portion, the structural parts being spaced from each other transversely to the longitudinal direction and defining therebetween a delimited working area. A hoisting apparatus is mounted on the machine frame, the hoisting apparatus comprising a load carrying device and drives for adjusting the load carrying device in vertical, longitudinal and transverse directions. |
