1917 by Sir William Arrol and Co Ltd for the Greenock
Harbour Trust. 150 ton grant, steel cantilever crane on the S
side of James Watt Dock. Lattice girder tower supporting
roller track on which rotates the asymmetrical cantilever
truss gib with motor room and counter weight at short end.
Statement of Special Interest
Constructed during the 1st World War then there was
great competition for materials. This crane was a
considerable achievement and is (1988) still in complete
working order. About 42 giant cantilevered cranes were
constructed world wide and the Glasgow firm of Arrols were
responsible for 40. 27 were located in Britain, 15 survive
but 7 (1988) are at serious risk. In Scotland 7 remain at
the 2 Arrol cranes at Rosyth are under Threat (1988).

Listing is the way that a building or structure of special architectural or historic interest is recognised by law through the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.
We list buildings of special architectural or historic interest using the criteria published in the Historic Environment Scotland Policy Statement.
The statutory listing address is the legal part of the listing. The information in the listed building record gives an indication of the special architectural or historic interest of the listed building(s). It is not a definitive historical account or a complete description of the building(s). The format of the listed building record has changed over time. Earlier records may be brief and some information will not have been recorded.
Listing covers both the exterior and the interior. Listing can cover structures not mentioned which are part of the curtilage of the building, such as boundary walls, gates, gatepiers, ancillary buildings etc. The planning authority is responsible for advising on what is covered by the listing including the curtilage of a listed building. For information about curtilage see www.historicenvironment.scot. Since 1 October 2015 we have been able to exclude items from a listing. If part of a building is not listed, it will say that it is excluded in the statutory address and in the statement of special interest in the listed building record. The statement will use the word 'excluding' and quote the relevant section of the Historic Environment Scotland Act 2014. Some earlier listed building records may use the word 'excluding', but if the Act is not quoted, the record has not been revised to reflect current legislation.
If you want to alter, extend or demolish a listed building you need to contact your planning authority to see if you need listed building consent. The planning authority is the main point of contact for all applications for listed building consent.
