HYDRAULIC RAIL THREADER H90461 / NO 10055
TYPE MPR – M
When the rails are removed, the Rail Threader can be moved via the hydraulic
transmission at a speed varying between 0 and 3.5 km/h. When the control levers are not
activated, the Rail Threader is automatically braked by the hydraulic motors.
4 – 6 Main frame
The Rail Threader main frame consists of a
double beam (1) and two movable extensions (2)
which enable the Rail Threader to be moved along a
3,330 mm track.
When fitting the extensions, make sure that the
assembly screws are greased and respect the torque
setting. (fig. 11)
(for the grease characteristics, see § 6.2.1
TABLE OF EQUIVALENCES OF OILS AND LUBRICANTS)
Fig : 11
For work under difficult conditions (in tunnels,
on slopes or with reduced centre distances, etc.) the
extensions can be replaced with closing plates (1).
The double beam then measures 3,058 mm
and no longer exceed the UIC circulation gauge if the
Rail Threader is centred on the site track. ( fig. 12)

Warning! risk of the limit being engaged using the extensions. Take the
necessary measurements.
