In certain aspects, a roller assembly includes a base structure defining multiple recesses that extend inwardly from a top surface of the base structure, a first wheel, and a second wheel. The multiple recesses are configured such that at least one of the multiple recesses is engageable with an auxiliary component of the load, and the multiple recesses include a central recess positioned at a center of the top surface of the base structure. The first wheel is disposed along a first side of the base structure, and the second wheel is disposed along a second side of the base structure, the second side of the base structure being spaced apart from and parallel to the first side of the base structure.
