The cranes are situated in the shipyard of Harland & Wolff and were constructed by the German engineering firm Krupp, with Goliath being completed in 1969 and Samson, in 1974. Goliath stands tall, while Samson is taller at. Goliath, the smaller of the two sits slightly further inland closer to Belfast City.
Construction
Each crane has a span of and can lift loads of up to 840 tonnes to a height of, making a combined lifting capacity of over 1,600 tonnes, one of the largest in the world. Prior to commissioning, the cranes were tested up to 1,000 tonnes, which bent the gantry downwards by over. The dry dock at the base of the cranes is the 6th largest in the world measuring 556 m × 93 m. The H&W logo was bolted onto the crane by Edward Salmon a shipyard worker who, before being apprenticed by H&W, sold newspapers at the entrance.
At its height Harland & Wolff boasted 35,000 employees and a healthy order book, but in the years following the cranes' construction the workforce and business declined. The last ship to be launched at the yard to date was a roll-on/roll-offferry in March 2003. Since then the yard has restructured itself to focus less on shipbuilding and more on design and structural engineering, as well as ship repair, offshore construction projects and competing for other projects to do with metal engineering and construction. Initially there was concern that the now largely redundant cranes would be demolished. However, later in the year they were scheduled as historic monuments under Article 3 of the Historic Monuments and Archaeological Objects Order 1995. Northern Ireland Office Minister of the time Angela Smith stated: "These cranes are an essential part of our city, our roots and our culture." The cranes are not, technically, ‘listed buildings’, but are recognised by the Northern Ireland Environment Agency as buildings of ‘architectural or historic interest’. Shipbuilding has ceased in Belfast, but the cranes are to be retained as part of the existing dry dock facility within the restructured shipyard, situated adjacent to the Titanic Quarter, a business, light industrial, leisure and residential development on land now surplus to the heavy industrial requirements of the shipyard on Queen's Island. They were still kept in working order and used for heavy lifting by Harland & Wolff in its other activities, however the company ceased trading in 2019.
Recent history
On 4 April 2007, Samson crashed into the long jib of smaller rail-mounted "Henson" tower crane, sending the smaller crane tumbling to the ground. The smaller crane weighed 95 tonnes and stood at a height of 25 m, compared to Samson's 106 m. Three industrial painters working on another rail-mounted crane were close to the jib as it fell, eventually crashing onto the ground. Information about the incident was not released until mobile-phone footage of the event was published on YouTube. In October 2007, Goliath re-entered service after five years, an occurrence described by a company spokesman as underlining the yard's growing workload.
