Abstract: A tool caddy has a wheeled horizontal platform from which a post projects rigidly upward near one margin of the platform. A support assembly is mounted on the post for movement in a vertical direction, and the assembly includes an upwardly-facing ledge. The combination includes a means for latching the support assembly at selectively different heights above the platform. A horizontal tray is positionable above the platform. A hanger rigidly affixed at one side of the tray is engageable over the ledge so as to support the tray removably above the platform. A handle is secured to the tray and is positioned thereabove in an orientation enabling disengagement of the hanger from the ledge upon an upward pull to the handle.
