Wheeled excavators are more versatile than their crawler counterparts, due to their greater maneuverability, which allows them to get to places crawlers cannot reach. However, tracked excavators, due to the bigger undercarriage surface, offer a greater working stability and less pressure on the ground, so can handle heavier loads on more uneven surfaces.

The Guria 520 LGP concept proposes a way to enjoy the best of both worlds. It has greatly reduced the ground pressure thanks to six independent outriggers: four universal and two extra-large stabilizers. Crucially, all of them are designed to fold within the overall machine dimensions, meaning transporting this compact vehicle is no more difficult than it would be for a traditional wheeled version.

This wheeled excavator is designed to offer a support surface two and a half times greater than a conventional wheeled excavator, making it similar to a HD crawler surface. These remarkably well-balanced characteristics would involve a higher lifting capacity for a wheeled vehicle. The machine also benefits from independent pivoting pads offering a greater working stability and higher performance.

In rural environments, ground care is especially important as arable sites, tracks and paths are prone to damage. Instead of creating four deep typical ‘footprints’, impact is minimized by the LGP system due to the higher contact surface and low ground pressure. Well matched to the job and terrain, it would suit rural contractors or farmers.
