Earlier this summer we introduced you to the new Yanmar Sigma excavator, the B7 Sigma-6
Yanmar dealers in Germany have supplied a Sigma machine which has made light work of a tough job, reconstructing a driveway, located on a steep slope.
With it's multiple attachment options, the excavator can be used for all manner of operations. Equipped with a hydraulic breaker it first broke the old driveway's concrete layer with a thickness of 40 cm. Thanks to the VICTAs system and centrally mounted boom the Sigma managed to keep a stable position despite the steepness of the job and tightness of some of the areas.
The driveway was surrounded by a garage, road and a wall so it was imperative that the machine could work and rotate fully within it's tracks - like a mini excavator. At the same time, it is able to precisely place heavy loads – just like a large excavator. Furthermore, it acts with high flexibility and accuracy thanks to its three piece boom.
After the concrete and the soil had been loaded onto the truck, the Yanmar excavator filled the driveway with gravel and lifted the concrete supporting angles putting them into their right position. Finally, the machine filled the mineral mixture into the ground and distributed it.
Owner and operator of this Sigma excavator said of the machine "We really like utilising the B7 Sigma for the garden and landscaping sector because of its flexibility. It is deployed in public green spaces as well as in private gardens”
