Mounting structure with storable transport system

#This disclosure relates generally to apparatuses for transporting a load, and more particularly to apparatuses for moving heavy loads over small distances with the ability to fine tune the resultant position of the heavy load.

#Moving extremely heavy loads has generally been a complicated task because the large forces involved in lifting and transporting the heavy loads. When possible, large loads are often transported by disassembling or breaking up the load into multiple smaller loads. However, this break-down and subsequent reassembly process can be very time consuming, especially when a heavy load is only to be moved a small distance, or needs to be repositioned.

#For heavy loads that need periodic movement or adjustment, devices commonly referred to as “walking machines” or “walkers” were developed. These machines typically move the heavy loads over small distances in incremental stages. Walking machines are particularly useful for moving large structures, such as oil rigs, which often times need to be moved in order to properly position them over pre-drilled pipes in oil fields, or moved to a new location that is undergoing oil exploration.

#FIGS. 1A and 1B are diagrams of walking apparatuses attached to various loads according to embodiments of the invention.

#FIGS. 2A, 2B, 2C, 2D, 2E, and 2F are detail diagrams showing an example operational progression of walking apparatuses to move a load according to embodiments of the invention.

#FIGS. 3A and 3B are diagrams illustrating example connection arrangements used to connect a walking apparatus to a load according to embodiments of the invention.

#As described above, walkers, or walking machines, are vehicles that are used for transporting very heavy loads, such as entire oil well drilling rigs. Such loads may be as great as several thousand tons and may be required to be sequentially positioned very precisely over spaced-apart well bores, for example. Embodiments of the present concept are directed to load transporting apparatuses, such as walking machines, for moving heavy loads over small distances with the ability to fine tune the resultant position of the heavy load. For ease of understanding, the terms, “walkers,” “walking machines,” “walking devices,” and “walking apparatuses” are used interchangeably below. Load transporting apparatuses or systems may include one or more walking machines. Additionally, a walking machine's subassembly of components that facilitate movement of the walking machine are referred herein as a “walking mechanism.” Walking machines may incorporate one or more walking mechanisms, depending on the specific configuration of a walking machine.

#For example, with reference FIGS. 1A and 1B, a load transporting system includes multiple walking machines that support a load being carried by the load transporting system. FIGS. 1A and 1B show examples of walking apparatuses attached to various loads according to embodiments of the invention. Referring to FIG. 1A, multiple walking apparatuses 115 are positioned under or adjacent to an oil rig 100. Typically, walking machines 115 are positioned at least near edge portions of a load 100 to balance the weight of the load over the various walking machines. However, specific situations may dictate that walking machines 115 are positioned in various other locations relative to the load 100.

#Referring to FIG. 1B, multiple walking apparatuses 116 are positioned under or adjacent to a silo 101. Although an oil rig load 100 and a silo 101 are respectively illustrated in FIGS. 1A and 1B, walking machines may be used to move any type of relatively large load, such as bridge sections, ship sections, structures, etc. Additionally, although two walking machines are shown in FIGS. 1A and 1B, more or fewer walking machines may be used to move loads 100, 101.
