Assembly of heavy stone façade elements

Heavydrive’s systems deployed in London to install special corner frames under overhangs

This construction project in London’s Wood Wharf district in July and August 2017 involved installing various-sized stone corner façade elements and façade insulation weighing up to a tonne. On top of that, the elements had to be lifted under an overhang of 1.5m. The assembly system needed to be controlled remotely so that there was no scaffolding in front of the façade.

To firmly place the various elements, the Polish façade manufacturer developed a special steel auxiliary structure. Following extensive deliberation with the Heavydrive experts, the decision was made to use Heavydrive’s VSG 2000 counterweight traverse in conjunction with the SWS quick-change head for assembly of the façade elements. Locating bore holes were welded to the auxiliary structure so the SWS could be attached. Before assembly could begin, the system was tested in the customer’s Polish assembly facility, and the counterweight traverse passed all testing with flying colours.

Safe, quick and competent assembly

Due to time constraints, the VSG 2000 counterweight was transported from the test location in Poland directly to the construction site in the British capital, while at the same time all of the auxiliary constructions were prepared for adaptation to the Heavydrive quick-change head. Using the SWS and with very few hand movements, the operator could replace the elements by pinning just three bolts.

In order to meet all of the requirements and guarantee the best operation of the Heavydrive equipment, the experienced Heavydrive assembly manager travelled to the construction site in London himself to train the on-site team and hand out the necessary certificates. At that point, the system could be handed over to the customer.

Heavydrive counterweight traverses for every construction site

Several months previously, Heavydrive GmbH was involved in a similar assembly situation for another building in London’s Wood Wharf district. On that occasion, conditions were even trickier due to the 3.5m roof overhang and the corner angles and steel auxiliary structure projecting out by 2.9m. Together, the auxiliary frames and corner elements reached a lifting load of 1,850kg, so the Heavydrive VSG 4000 counterweight traverse – with a capacity of up to 4 tonnes – was used in this assembly project.

There is a large range of counterweight traverses from 500kg to 12,000kg available to rent and to buy from the Heavydrive headquarters in Tapfheim. The systems can be configured and customised to the customer’s specifications. The professional Heavydrive team is on hand to help you choose the right device.
