US Patent 9353593 Handler for blowout preventer assembly

A handler holds a blowout preventer (BOP) assembly (partially or fully assembled) for transport and then erects it from a transport position to a vertical position for deployment. In the transport position the BOP assembly generally rests in a horizontal position. During deployment of the BOP assembly by the handler, the handler is capable of moving the BOP assembly to a vertical position, elevating it, and moving it outward, away from the base of the handler and toward a wellhead, so that the BOP assembly may be connected to a coiled tubing injector, work may be performed underneath the BOP assembly before connection to a well head, and the BOP assembly may be placed on top of a well head for connection to the well head.
