Patent number: 11407460Abstract: 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.Type: GrantFiled: May 16, 2019Date of Patent: August 9, 2022Assignee: ENTRO INDUSTRIES, INC.Inventors: Harlan B.

Patent number: 11180319Abstract: 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.Type: GrantFiled: October 22, 2018Date of Patent: November 23, 2021Assignee: ENTRO INDUSTRIES, INC.Inventors: Harlan B.

Patent number: 10889961Abstract: 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.Type: GrantFiled: February 14, 2018Date of Patent: January 12, 2021Assignee: ENTRO INDUSTRIES, INC.Inventor: Brian Unger

Patent number: 10793409Abstract: A control system detects a loaded state for a lifting device. The control system receives a current load value from a load sensor corresponding to a load on the lifting device and compares the current load value from a previously received load value to determine a change in load. The control system receives a current displacement value from a displacement sensor corresponding to a displacement of the lifting device and compares the current displacement value with a previously received displacement value to determine a change in displacement. The control system compares the change in load with the change in displacement to determine a current load slope. The lifting device in identified in a loaded state based on a comparison of the current load slope with a load slope threshold.Type: GrantFiled: November 8, 2017Date of Patent: October 6, 2020Assignee: ENTRO INDUSTRIES, INC.Inventor: Brian Unger
