The road-rail excavator proposed by Railshine Rental offers a key advantage: it doesn’t have any oscillating rail axle. The manufacturer designed the rail axle arms so that there are flexible enough to successfully pass the track twists, and strong enough to bear off-centred loads without the need of locking any rail axle. The driver has a particular interest in this feature since, finally, it exists one machine that enables to travel back and forth on the rail track with an off-centered load, without need of locking/unlocking an oscillating rail axle, knowing that this operation is very often needed during earth-moving works.
