Some embodiments may include a coil tubing injector, which may include: a cylinder-rod assembly including at least one cylinder rod operably coupled to a first load beam and a second load beam, the at least one cylinder rod to change a separation distance between the first load beam and the second load beam; opposing grippers; and at least one additional beam, at least one link, a set of gears, or control valves to maintain a parallel orientation of the load beams relative to each other during operation of the at least one cylinder rod, the at least one additional beam, the at least one link, or the set of gears operably coupled to at least one of the load beams or the control valves coupled to hydraulic piping to hydraulically operate the cylinder-rod assemblies independently. Other embodiments may be disclosed and/or claimed.

Coil tubing injector

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.

Nonlinear walking apparatus

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.

Skid system for load transport apparatus

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.

Yaw alignment system

Embodiments relate to a system or method for moving a load, the apparatus may include a control panel comprising an assemblage of one or more directional switches that are configured to activate a lift mechanism structure to lift a load-bearing frame supporting the load. The one or more directional switches configured to adjust a travel mechanism that is coupled to a roller track and connected to an electrically positionable roller assembly and adjust a pin connector that is configured to connect a support foot to the roller track to allow the roller track to rotate relative to the support foot.

Control system for load transportation device

A low-profile roller assembly reduces an overall mounting height of walking machines enabling use in a wider variety of structures and locations while also reducing complexity and over cost. The low-profile roller assembly may include a roller device with a substantially flat roller cage with one or more slots configured to hold a single layer of rollers. The roller device may move longitudinally relative to a support foot and a load plate may move longitudinally relative to both the support foot and the roller device. The load plate may laterally displace relative to a longitudinal axis of the support foot or may laterally displace relative to longitudinal axes of both the support foot and the roller device.

Low profile roller assembly

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.

Detachable multi-axle assembly

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.

Mounting structure with storable transport system

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.

An axle assembly for transporting a load bearing frame includes a first axle operably coupled to an axle mount of the load bearing frame by a first articulation structure, and a second axle spaced a distance from the first axle and operably coupled to the axle mount by a second articulation structure. The first articulation structure is rotationally coupled to the axle mount by a first articulation connection, and the second articulation structure is rotationally coupled to the axle mount by a second articulation connection. A suspension system is operably coupled to both the first articulation structure and the second articulation structure. In a first mode of operation, the suspension system forms a substantially rigid connection between the first articulation structure and the second articulation structure. In response to an upward articulation of the first articulation structure towards the load bearing frame, the substantially rigid connection causes the second articulation structure to articulate down and away from the load bearing frame. In a second mode of operation, the suspension system articulates both the first articulation structure and the second articulation structure towards the load bearing frame.

Articulating multi-axle assembly

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.

Axle assembly

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.
