The wire rope hoists lift between 3 t and 6 t and are radio remote controlled. The wall-mounted travelling cranes work along the crane runways, the jib cranes serve the fringe and move loads around the corners of the building. The wall mounted travelling cranes and jib cranes cover the whole area around the tower. “Without the swift, magnificent support of our partner Prime Source the project would not have been possible.” Hildebrandt was able to demonstrate above average project experience right at quotation stage: less than 24 hours passed from initial contact to order – including technical clarification and the quotation for the first eight cranes – the final crane was erected four months later.Īs both the dial components and the innumerable sections of building cladding had to be transported right against the walls of the building, tower cranes were ruled out for this work. “Owing to the very tight project schedule the customer was looking for a crane supplier with above-average project experience,” says Frank Hildebrandt, Managing Director of STAHL CraneSystems in Dubai.

The clock is intended to be seen from a distance of nearly 20 kilometres, and as it stands right next to the holy mosque, replace Greenwich as temporal reference point – for the Islamic world at least.įor the installation of the gigantic clock STAHL CraneSystems supplied 23 wire rope hoists installed on wall mounted jib cranes at varying heights on the tower facade. Over 2 million LEDs provide illumination five times a day, at prayer time, the dials flash green. Each of the four dials is studded with 98 million glass mosaic tessera.

The largest tower clock in the world has been ticking away above the Masjid al Haram Mosque since August 2010: 80 m high, 65 m wide, the dials are 39 m in diameter. Only the Burj Chalifa in Dubai is even higher at 830 metres. When it is completed this year, the Royal Clock Tower Hotel will for some time be the second highest building in the world. The tower resembles London’s Big Ben, but is six times as high as the original. Floor area: 1.5 km², 96 floors and a 601 metre high clock tower as the crowning touch. The hotel and luxury residential complex Abraj al-Bait, also known as “Royal Clock Tower Hotel”, is being constructed right in the centre of the city.
