Industrial Design Excavator

The walking excavator is not a new idea, but I think future adaptations in a mid-size product line such as a new Liebherr 417, with updated cab styling of the interior for advanced in-cab computer power could be promising..

This machine slews like a standard excavator for dumping the spoil, as the main pivot between the upper and lower sections remains relatively the same. But the lighter construction of the arms, and cabin made from a reinforced polymer – enables the machine to adjust its balance to move heavier materials in the bucket without pulling itself off its feet. Combined with the larger footprint to reduce ground pressure, multiple function levelling gives operators increased performance for sensitive areas, such as city maintenance of underground cables and piping, or where landscaping might need to be left relatively untouched in sensitive environmental areas.

This concept might appear like a cumbersome mechanical elephant but, just as in nature where large animals create efficiencies to live and move about successfully, the improvements in robotics and energy efficiency come into play with this design. The idea of a fuel cell hydrogen-electric hybrid came to mind and the concept reflects this in the hydro-blue colour accents and LED light piping. The fuel cell-look is encapsulated between the chassis and upper housing promoting the advanced technology inside.
