ABSTRACT:
The manipulation of components of a fluid transmission system, particularly portions of a conduit through which heated gas is delivered to a blast furnace is facilitated by the use of a self-propelled vehicle having mounted thereon a component support mechanism. The vehicle and component support mechanism cooperate to define a pair of displaced vertical pivotal axes whereby the component support mechanism can be readily maneuvered into engagement with the conduit portion to be manipulated. The apparatus is further characterized by a lifting arm assembly which enables the component support mechanism to be raised and lowered without changing the orientation of a supported conduit portion.
