Abstract
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.
