A cart includes a chassis including one or more frame members, one or more casters, a first channel and a second channel coupled to the chassis, the first channel defining a longitudinal axis and the second channel defining a lateral axis. The first channel and the second channel each include a pair of guides each including a first portion and a second portion and a flat member coupling the guide to the frame members. The first portions extend substantially parallel to one another. The second portions are angled to increase a distance between the second portions as the second portions extend away from the first portions.

A vehicle system includes a first vehicle and a second vehicle. The first vehicle includes a first drive motor configured to drive one or more of a first plurality of tractive elements to propel the first vehicle, and a first cradle configured to support a product at a first end thereof for movement. The second vehicle includes a second drive motor configured to drive one or more of a second plurality of tractive elements to propel the second vehicle, and a second cradle configured to support the product at a second end thereof for movement. The first vehicle and the second vehicle move the product via at least one of the first drive motor or the second drive motor.
