ATLAS presented its road-rail excavator 1604 RR prototype at the IAF fair in Münster. It looks more dynamic and has become more digital. Entering the 250 mm higher superstructure in now possible through the rear of the cabin. Inside the cabin, toggle switches and both displays have been replaced by a 12“ touch screen. Operating the 16 different working tools can now be done digitally via touch screen. The all-round view is impressively well. Especially due to the reclined superstructure on the right, the driver receives a clear view and therefore security. This is unique.
Road-rail short-tail excavator – better hydraulics
The new hydraulic control block, which replaces the previous two control blocks, is more sensitive and technically more compact. ATLAS has completely re-developed the track control. It is more stable on an even track and offers substantial advantages on a superelevated track. A new motor and brake-valve as well as the levelled hydraulic chassis enable differentiated movements back and forth and offer even more steadiness. The ATLAS 1604 RR exists in two different rear radius variants: 1,950 mm and 1,750 mm. The counterweight is built-in and therefore this new ATLAS is a proper short-trail excavator. Additionally, the mechanics for additional weight has been altered and can be mounted more easily. The rigid axle consists of a 100% switchable limited slip differential.
Emissions standard Euro V
The new Deutz engines with 115 KW / 157 PS meet the emission standards of EU Stage V / US EPA. They are quiet with 97 dB (A) outside and 71 dB (A) inside and are equipped with an exhaust aftertreatment system with a closed diesel particle filter and combined SCR catalytic converter. The 1604 RR road-rail excavator is outfitted with the proven Linde Load-Sensing-Hydraulics. The intelligent ATLAS hydraulic management AWE 4 enables a load-independent superimposition of the work movements.
Even better, to the last detail
The 1604 RR has a weight of 22 t and a maximum range of 8,700 mm (depending on the attachment). It has been refined in its details. The hydraulic tank is bigger now. To achieve a more favorable route of the hydraulic hoses, the lifting cylinders have been turned around. If required, a manual hydraulic pump is easily accessible in the toolbox beside the additional compressor. Working in the dark is now much easier. Dreier lights to the front and the rear illuminate the working area brightly. The ATLAS 1604 RR road-rail excavator does not only look more contemporary, it also is technically a huge progress. The market launch is anticipated to take place after the new inspection.
