Abstract
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.
