The equipment can be supplied for any rail gauge type.
This portal has been developed for handling and laying railroad switches (turnouts), track panels, or sleepers.
The portal structure is made of sturdy electro welded steel.
The cabin, with its command panel, the engine and the hydraulic power unit are placed on the main body. The equipment is supplied with a button board for remote controlling all operating functions.
The vehicle can drive on crawlers or on rail wheels, and is totally independent during both the removal phase and the material laying phase, as well as when driving to the work site. When it has to be transported for long travels, the T28 portal can load/unload itself autonomously on wagon or semitrailer. Two vertical hydraulic columnss – instrumental to the portal lifting – allow the right and left crawlers positioning even on surfa- ces at differential levels, thus constantly maintaining an horizontal loading set up, and allowing a stable movement of the equipment.
The portal is also equipped with four vertical hydraulic cylinders,
for standing on rail wheels, and with four hydraulic cylinders for lifting sleepers/rails/track panels/switches.
The lifting system is adjustable on the horizontal plane on a range of
+/- 5° and on the vertical plane on +/- 2° 30’, in order to smoothly drive on rough and uneven terrain. The equipment avails an artificial horizon in order to automatically maintain the load in horizontal position, even when the portal is on a uphill or downhill path. Horizontal hydraulic cylinders for crawler open/close operations, and for managing the frame, which handles the load, are provided as well.
