Titan Clydebank



Titan Clydebank is a 150 ft cantilever crane at Clydebank, Scotland. It was designed to be used in the lifting of heavy equipment, such as engines and boilers, during the fitting-out of battleships and ocean liners at the John Brown & Company shipyard. This was also the world's first electrically powered cantilever crane, and the largest crane of its type ever built at the time of its completion.

The crane was used to construct some of the largest ships of the 20th century, including the Queen Mary, Queen Elizabeth and Queen Elizabeth 2. The Category A Listed historical structure was refurbished in 2007 as a tourist attraction and shipbuilding museum.

History
The yard at Clydebank was created in 1871 after operations were moved by brothers J & G Thomson from the Graving Docks in Govan. John Brown & Company took over in 1899, and in 1905, a £24,600 order for the crane was placed with Dalmarnock based engineering company Sir William Arrol & Co. Titan was completed two years later in 1907. It was constructed by the Scottish engineer Adam Hunter, who was working as Chief Engineer for Arrol & Co., having served his apprenticeship on the construction of the Forth Bridge. Stothert & Pitt of Bath, England, fabricated and installed the machinery for the Titan including electric motors built by Lancashire Dynamo and Motor Co.

When tested on 24 April 1907, Titan was the largest cantilever crane ever built with a 160 t capacity at a radius of 85 ft. The original 160 t lift capacity was upgraded to 200 t in 1938, when it became apparent that the original specification would be insufficient to lift new long range gun barrels onto ships such as the Duke of York.

On the nights of the 13 and 14 of March 1941, the Clydebank Blitz virtually destroyed the town. 528 civilians were killed, over 617 people were seriously injured, and 48,000 civilians lost their homes. Only seven properties in Clydebank were undamaged, and the destruction was among the worst in Britain. The raids, involving 260 Luftwaffe bombers on the first night and 200 on the second, targeted the industry of Clydeside, but the Titan crane was undamaged.

In the late 1960s, the yard was incorporated into Upper Clyde Shipbuilders (UCS), which collapsed in 1971. It was bought from the receivers by the Marathon Manufacturing Company for oil rig construction. In 1980 Marathon sold the yard to the French company Union Industrielle et d’Entreprise (UiE). UIE's owners, Bouygues Offshore closed the yard in 2001 and the site was earmarked for redevelopment.

Ships constructed by the crane include HMS Hood, the Queen Mary, Queen Elizabeth, Queen Elizabeth 2, and the Royal Yacht Britannia.

Refurbishment
The crane fell into disuse in 1980s, and in intervening period of neglect vandalism to the wheelhouse and corrosion had taken place. In 1988 the crane was recognised as a Category A Listed historical structure.

The urban regeneration company Clydebank Re-Built started a £3.75m restoration project in 2005, and the crane opened to the public in August 2007. The structure was shot-blasted to remove old paint and rust, allowing repairs to be undertaken before repainting. A lift for visitors to ascend to the jib and an emergency evacuation stair were installed, along with a wire mesh around the viewing area and floodlights to illuminate the crane at night.

Design
The Titan used a fixed counterweight and electrically operated hoists all mounted on a rotated beam, making it faster and more responsive than its steam powered predecessors. Titan is 49 m high, weighs about 800 t and sits on four concrete piles sunk to a depth of 23 m deep. The arms of the cantilever are 45.7 m and 27.4 m long. The tower is 12 m square, and its centre sits just 10.7 m from the edge of the quay.

Following the removal of the Titan crane at Govan Shipyard in 2007, there are now four giant cantilever cranes on the River Clyde. The others are at Stobcross (Finnieston Crane), Scotstoun (former Barclay Curle engine works) and Greenock (James Watt Dock). Fewer than sixty giant cantilever cranes were built worldwide, six of them on the Clyde, and as of May 2011, it is believed only eleven remained, four of those on the Clyde.

Awards
It was awarded the 2012 Engineering Heritage Award, by the Institution of Mechanical Engineers. Titan was designated as an International Historic Civil and Mechanical Engineering Landmark by the American Society of Civil Engineers in 2013, the fifth such award given to a Scottish structure.

For the restoration of the structure, recognition was accorded by Chicago Athenaeum Award for Architecture in 2008 and by the Civic Trust in 2009.
