摘要： An alignment assembly is coupled between a steering assembly and a support foot to maintain an alignment of the support foot with the load transport assembly while the steering mechanism rotates in different steering directions. A biasing device activates in response to non-linear displacements of the load transport assembly relative to the support foot and moves the steering assembly and the support foot back into original alignments with the load transport assembly. The alignment assembly may include a lower main gear assembly that rotates the support foot relative to the steering assembly and an upper main gear assembly that rotates the steering assembly relative to the load transport assembly.

摘要： 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.Other 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.

摘要： A multi-axle assembly includes an axle frame configured to move in a first travel configuration, a first axle assembly attached to the axle frame and including a first axle, and a second axle assembly attached to the axle frame and including a second axle. A common axis of rotation passes through both the first axle and the second axle in the first travel configuration. A first axle mount that operably couples the first axle assembly to the axle frame, and a second axle mount that operably couples the second axle assembly to the axle frame. Both the first axle assembly and the second axle assembly may be repositioned to a second travel configuration in which the first axle and the second axle are rotationally offset from the common axis of rotation.

摘要： A mounting structure for a rig may include a base configured to support the mounting structure on an operating surface and a plurality of transport systems operatively connected to the base and configured to lift the mounting structure off of the operating surface. An elevated rig platform may be connected to the base by a plurality of support struts, wherein at least some of the support struts comprise a mounting connection that is configured to pivot to lower the elevated rig platform toward the base and place the mounting structure in a partially collapsed state. Additionally, a connecting member may be attached to one or more of the plurality of transport systems, wherein in response to the elevated rig platform being lowered to the partially collapsed state, the connecting member may be configured to displace at least a portion of the one or more transport systems.

摘要： An axle assembly includes an axle, an axle mount configured to be attached to the axle, a positional locater that projects from an outer surface of the axle and is configured to locate an initial position of the axle relative to the axle mount, and an axle adjustment device comprising an inclined surface that contacts the positional locater. A compressive force is exerted between the axle mount and the axle adjustment device when the axle adjustment device is placed in contact with the positional locater to maintain the initial position of the axle.

摘要： A removable axle assembly for transporting a load bearing frame includes an axle mounting structure configured to be removably attached to an axle mount. The axle mounting structure includes an inner surface that is aligned with a tapered surface of the axle mount. One or more fastening devices are attached to a clamping structure. In response to securing the one or more fastening devices, the clamping structure is configured to exert a compression force that maintains contact between the tapered surface of the frame support structure and the inner surface of the axle mounting structure.

摘要： A load transporting apparatus includes a base structure that supports a load and a plurality of transport devices that move the base structure over a base surface. A first group of transport devices concurrently contact the base surface during a first movement step. Following the first movement step the first group of transport devices are disengaged from the base structure during a second movement step of the base structure. A second group of transport devices are disengaged from the base surface during the first movement step. Following the first movement step the second group of transport devices contact the base surface during the second movement step, and the weight of the load supported by the first group of transport devices is transferred from the first group of transport devices to the second group of transport devices.
