One particular application of the invention relates to use in association with ductwork or piping where it become necessary to service an element in such ductwork or piping. Such servicing generally requires the removal of the element from the ductwork or piping and then subsequent reinstallation of the serviced item or installation of a replacement item. In most cases the most common means for removal or placement of such items comprises the use of a crane and whilst this can be convenient during the construction phase of a plant it is not so convenient once the plant is operating and in fact may not be possible due to the location of the element to be removed and the site.
A particular application of the invention relates to use with flanged pipes which are interconnected through their flanged connections and/or which accommodate flow control or sensing elements through their flanged connections.
