In some embodiments, a method and apparatus are described for moving heavy objects while providing for precise movements and alignments along any desired path, making the apparatus ideally suited for moving heavy equipment including tunnel boring equipment or structures, such as land drilling rigs. In certain embodiments, an apparatus may include at least two load bearing subassemblies. Each load bearing subassembly can include a support structure configured to support a load, a bearing mat; and a plurality of linear actuators coupled between the support structure and the bearing mat. The plurality of linear actuators may be configured to raise, shift, and lower the load relative to the bearing mat or reference base to move the load.
