ABSTRACT:
Apparatus for supporting an extendable, elongated tool-handling boom within a gantry. The back end of the boom is rotatably supported in a carriage that is movably mounted in a gantry while the main body of the boom forward of the carriage is seated upon a rest carried within a cradle which is also movably mounted within the gantry whereby the relative position of the two boom support points can be altered as the boom is extended and retracted within the gantry. The boom is able to be lifted from the cradle seat in the event it becomes hung-up upon an obstacle while in use thereby preventing the boom from being damaged. A shock absorber is operably connected between the cradle and the boom which serves to return the boom to the cradle seat at a controlled rate.
