Titanic

The company was contracted by Harland and Wolff Shipyard, Belfast, to construct a large gantry (known as the Arrol Gantry) for the construction of three new super-liners, one of which was called the RMS Titanic. Like the ships themselves, the gantry crane was one of the largest built at the time, comparing with transporter bridges in length, height and capability.
