Heavydrive technology in use at the world's second tallest skyscraper in Mecca
The centerpiece of the architectural masterpiece sparkles in the sun like a huge, polished diamond. Heavydrive® was also involved in the gigantic hotel project, at the heart of which is the second tallest skyscraper in the world - the "Mecca Royal Clock Tower", which is based on the clock tower of London's Big Ben and is around 602 meters high.
Where others usually reach their limits, the transportation and lifting specialist rose to the challenge.
The challenge:
Glazing the dome from outside of the building with panes weighing 1,800 kg at a height of about 560 m.
The solution:
Development of seven different MRK cranes Heavydrive’s own construction: a 3-axle manipulator walk-in basket attached to a truck-mounted crane

Around 400 triangular and trapezoidal glass panes of different sizes in the shape of a polished diamond had to be mounted on the façade of the Royal Clock Tower at a dizzying height. A tricky task in which the Heavydrive ® inventors were able to demonstrate their planning skills in the design.
Mini cranes with vacuum suction systems for overhead installation enable them to be used at a wide variety of angles on the building.
The cranes with special overhead manipulators are designed to lift extremely heavy glass panes even at lofty heights. For example, a 3-axis manipulator in the form of a basket, which is adapted to a mobile crane, enables the heavy panes weighing 1,800 kilograms to be inserted precisely on the outside, even at a height of 560 meters. Workers place their heavy and fragile load optimally in an accessible cabin.
This is unique to date. A world first, for which Heavydrive received TÜV approval without any problems. This means that for the first time, people at a height of 602 m can precisely insert the façade panes directly on site by remote control. The Heavydrive lifting platform will remain permanently installed on the tower in the future. This means that the glass façade can be cleaned very easily. And if a pane needs to be replaced, this can also be done with little effort.
