A load transporting apparatus is configured to move a load bearing frame carrying a load over a base surface. A support foot provides a first load bearing surface. A lift mechanism during a step operation raises the support foot off of the base surface, lowers the support foot onto the base surface, and raise the load off of the base surface. A first travel mechanism moves the lift mechanism and attached load along a non-linear horizontal path and a second travel mechanism moves the lift mechanism along a different horizontal path. A control system operates the first travel mechanism and the second travel mechanism to move the lift mechanism along a selected horizontal path.
B62D 57/02 - Vehicles characterised by having other propulsion or other ground-engaging means than wheels or endless track, alone or in addition to wheels or endless track with ground-engaging propulsion means, e.g. walking members
A walking apparatus uses a unique single substantially planar interface between the top of support foot and the bottom of load plate to move a load both laterally, longitudinally, and in any curved, angular, diagonal, or non-linear direction. The single substantially planar interface used for moving the load plate in different directions provides the walking apparatus with a low vertical profile that can be installed in load bearing frames with lower ground clearances. In one example, a load bearing device provides a single steering plane movable over a support foot in different directions. A travel mechanism is coupled between the support foot and the load bearing device and is configured to change a horizontal path of the load while the weight of the load is transferred onto the support foot and the travel mechanism is moving the load relative to the support foot.

Automatic walking for a load transporting apparatus
A control system retracts lifting devices to a stored reset height during a reset operation to raise support feet off of a base surface. The control device raises a load to a stored moving height above the base surface during a moving operation. The control system automatically repeats the reset and moving operations using the stored reset and stored moving heights. The control device may receive an adjustment signal identifying anew height of the support feet or load bearing frame above the base surface and uses the new height during subsequent reset or moving operations. The control device may default to a minimum reset height or a minimum moving height when the new height would cause the support feet or load bearing frame to drag on the base surface.

Alignment restoration device for load transporting apparatus
Embodiments of the present invention are directed to a load transporting apparatus that automatically aligns a support foot of the apparatus with a load-bearing frame connected to the load transporting apparatus during a recovery phase of an incremental walking movement. In particular, the load transporting apparatus includes a linking device attached to a support foot of the apparatus and a biasing device connected to the linking device that is deflected during non-linear load transporting movements, where the biasing device acts to automatically return the support foot to an aligned position relative to the load-bearing frame after a non-linear movement has been completed and the support foot is raised above a ground surface.

Embodiments of the present invention are directed to a load transporting apparatus that automatically centers a support foot of the apparatus about a roller assembly during a recovery phase of an incremental walking movement. In particular, the load transporting apparatus includes guide devices positioned adjacent to a roller assembly that deflect a biasing device during non-linear load transporting movements, where the biasing device acts to automatically return the support foot to a centered position relative to the roller assembly after a non-linear movement has been completed and the support foot is raised above a ground surface.
