Lumede/Oliver Becker DesignSHEEPSFOOT TYRES

The CompactAll is a padded drum and tyre roller designed for the medium- and large-scale compaction of semi-cohesive and cohesive materials. Traction on this sheepsfoot concept would be provided by three hydrostatic motors, for the drum and the independent rear tyres. The lack of a rear axle allows for a very low location of the drivetrain, which also provides enough space for a six-cylinder engine and its aftertreatment, fulfilling Tier 4 Final without compromising the height and shape of the hood.


Outstanding stability would not just be provided by the very low centre of gravity, as the independent wheel position system would turn the roller into a full hillside machine when working on slopes. The suspended wheels would offer a more cushioned movement on uneven ground. The design of the bi-material tyres is intended to replicate the drum effect and to improve side grip while compacting on slopes.


Integration of the steering wheel and seat would enable the 360º rotation of the cockpit so the operator could choose the best view for working. For instance, in order to achieve the best compaction outputs, a second pass can be easily carried out by rotating the operator station by 180º. The rotating cockpit would be especially useful on narrow paths or areas, as there would be no need for steering the roller.


The cab is based on a three-double-post structure; this design splits every post into two pillars and creates profiles so slim as to be almost invisible. Visibility is also boosted by 7.5m2 of glass and a complete set of working lights for night operation. Permanent LEDs are included as a day safety feature. The shape of the bonnet is also designed to improve visibility from the 180º positions of the operator station.


The cab is accessible from both sides by means of two sets of steps that can be rotated in order to fill the fuel tank or reach other components. The AdBlue tank, located at the rear of the cab, can be easily reached from the cab access platform. Engine parts and batteries are easily and safely accessible from the counterweight by means of electrohydraulic engine bonnet tilt.

The design language for this concept is based on a rectangle with two round sides, which can be seen right from the structural components through to the styled ones.
