Abstract
Abstract A pneumatic tire transporter is provided for dismounting and transporting a pneumatic tire, tire carcass or the like from a collapsible tire building drum. The transporter includes a transport cage frame capable of being positioned circumferentially about a portion of a pneumatic tire assembled on a collapsible tire building drum. A plurality of support pads are spaced about and slidably supported on said cage frame preferably in two spaced circumferential sets. The support pads are capable of moving radially inwardly to engage the pneumatic tire assembled on the building drum at least adjacent opposite axial end portions of the building drum. The cage frame is supported and moved by a transport base member that is capable of moving the cage frame horizontally to dismount said pneumatic tire from the collapsible building drum and preferably thereafter rotating said pneumatic tire to a vertical position for detaching the detachable means and the pneumatic tire from the remainder of the transporter.
