This first 19th Century illustration relating to "The Mystery of the Victorian Fairbairn Tubular Crane on Esplanade Quay, Dover Marina" (see below) is taken from the 1877 book, "The Life of Sir William Fairbairn, Bart" (1), an autobiography and biography by Sir William Fairbairn and William Pole.

Accompanying text (abridged):

In November 1850, Mr. Fairbairn took out a patent for an invention which was very successful, namely an improvement in the instrument called a crane, for hoisting and lifting purposes. Ordinary cranes are usually constructed on one of the plans shown in the two first figures of the drawing.

In these the inclined strut, called the 'jib,' is placed at an angle of about 40 or 45 degrees with the vertical, so as to obtain the greatest strength. But if the article to be raised be at all bulky, this position of the jib will interfere with the height to which it may be raised.

Mr. Fairbairn's improvement consisted in making the projecting arm of the crane of iron plates riveted together so as to form a hollow tubular girder of curved form, as shown in the third figure. It allowed the article to be raised to a greater height, and at the same time offered greater strength and security.

There's an 1868 Fairbairn swan-neck tubular crane (2) similar to the one in the drawing located on Esplanade Quay, once called Ordnance Quay, on the southern side of the non-tidal Wellington Dock in Dover Marina.

Wellington Dock is a Grade II Listed Building (3). The following extract is © Crown Copyright and reproduced under the terms of the Click-Use Licence (PSI licence number C2010002016):

CRANE: The crane is a small hand-driven rotatory crane with swan-necked jib of riveted box frame construction. It was built by the Fairburn Engineering Co. of Manchester in 1868. It was once used by the Ordnance Department and was originally capable of lifting 50 tons. It was later de-rated to 20 tons and used for lifting yachts out of Wellington Dock. (Source: English Heritage)

A minor mystery concerns whether or not this Victorian crane is a "small hand-driven rotatory crane", as described above, or a decommissioned steam-powered crane whose performance specification was downgraded ("de-rated to 20 tons") at some unknown point in the past, perhaps as a result of the power unit being removed.

The questioning of the crane's original power source arose as a result of resolving a discrepancy in the spelling of the manufacturer's name: English Heritage state, "It was built by the Fairburn Engineering Co. of Manchester in 1868", while the nameplate is inscribed with, "The Fairbairn Engineering Company, Limited. Manchester" (ex-William Fairbairn and Sons).

The "Accompanying Text" in the caption to There`s more to the Dover Victorian Fairbairn Crane than meets the Eye has provided a clue as to how the Dover Fairbairn Crane was first powered.

A link to the full explanation will be added here once it has been uploaded.
