ABSTRACT:
An arrangement for limiting the extent to which telescopically mounted sections (1,2,3) can be extended is enclosed in a chamber (7) between each pair of sections, so as to be out of the way of personnel handling the sections. The arrangement comprises two mutually co-acting devices which have the form of hollow bodies (5) and which are intended to engage one another when the sections of a pair of sections are extended to a maximum. The mutually facing surfaces of the hollow bodies are preferably provided with a damping ramp section (8).
