Big jobs for the Atlas 140 W ‘bigfoot’ all terrain excavator

The ATLAS 140 W is equipped with huge 710/45-26.5 20 PR tyres and an undercarriage developed for working on marshy wet ground. The 140 W also has a speed of 30kph on roads and pathways so it can be used for all types of jobs on both difficult wet terrain and on the road,” said Frank König, employee of the local authority maintenance association Untere Oste, based in Hemmoor, a small town in northern Germany. The association maintains nearly 600km of waterways, pumping stations, polder and barrage pumping

“Bigfoot” with the big feet is the Atlas 140 W all-terrain excavator

The ATLAS 140 W is equipped with huge 710/45-26.5 20 PR tyres and an undercarriage developed for working on marshy wet ground.

The 140 W also has a speed of 30kph on roads and pathways so it can be used for all types of jobs on both difficult wet terrain and on the road,” said Frank König, employee of the local authority maintenance association Untere Oste, based in Hemmoor, a small town in northern Germany.

The association maintains nearly 600km of waterways, pumping stations, polder and barrage pumping stations, sluices, culverts and various earthslides and bed pitches.

In order to generate extremely low ground pressure, 7985 Atlas chose ultra-wide tyres with dimensions of 710/45-26.5 20 PR and designed the undercarriage to not restrict any operating movements. Bigfoot features enormous ground clearance and a low ground contact pressure without, however, exceeding an overall height of 4m.

To travel over the ground as lightly as possible, the axles have a limited slip differential of 35%, which prevents wheel spin and the excavator from getting bogged down in muddy or marshy ground.

With an optional second jib, the reach is 11m at which it still lifts loads of 1.2tonnes without the need for stabilisers.

Power is supplied by a 4-cylinder 201 Deutz engine with 80kW of power and diesel particle filter. The machine is equipped with a load sensing high-performance piston pump which controls various work movements simultaneously and independent of each other.

There is an attachment kit for up to 10 hydraulic tools, including hydraulic hammer and vibration pile driver, all of which can be controlled from cab. The hydraulic system was adapted to ensure consistent pressure and oil supply for powered units like mowers or mulchers and to keep the wear of the tools at a minimum.

During mowing operations with an oil flow of 26litres/min and a constant pressure of 180bar, none of the tools’ movements will cause a loss of performance. Average engine speed is 1,480rpm, which means that it consumes less than 6.3liters of fuel per hour.

    When the job is high up, then Schäffer’s new 5650 Z wheel loader with a bucket capacity of 0.8m3 and a working weight of 4.5tonne is up for the challenge. The 5650 Z has a powerful 37kW Kubota engine with four-valve technology and is the first such machine to feature electric drive control which permits significant increases in efficiency. Electronic support helps to optimise engine output and transform it into thrust, which results in reduced fuel consumption. The electronic control furthermore enabl

    German firm Atlas has developed two new high performance truck loading cranes, the 186.3VB and the 129.3V. The cranes have a lower deadweight than previous models in this class and the 186.3VB model benefits from a centrally placed crane column that provides a large range of movement as well as high stability to both sides. The 186.3VB crane has extension cylinders fixed at the tip of the jib, a standard recycling valve and heavy duty supports. The short set-up time achieved due to the fast extension speed
