Abstract
A cart includes rolling members and a frame connected to the rolling members. The frame provides a ladder-storage space. The frame also is configured to hold a ladder in a substantially vertical position with at least a portion of the ladder in the ladder-storage space. The rolling members form a rolling-member perimeter. The ladder-storage space can be disposed within the rolling-member perimeter in the vertical direction. The frame can include a base having a ladder-support surface for contacting and supporting a ladder. The ladder-support surface can be disposed below tops of at least some of the rolling members.
