ABSTRACT:
A tube stabbing apparatus uses a detachably mounted strongback to support a movable platform upon which a hoist assembly is carried. The platform and hoist assembly is positioned within a boiler chamber adjacent the steam drum of the boiler chamber in order to lift and position generating tubes for cooperative insertion into the steam drum. The platform and hoist assembly is movable in a horizontal plane and has a detachable boom which may be replaced with a longer boom as necessary to install each of the tubes. The entire apparatus is disassembleable to facilitate removal of the apparatus through a very small access opening in the boiler chamber.
