Heavydrive installs 400kg stone slabs under a pitched roof


Heavydrive’s lifting devices don’t just assemble glass panes, they can also be used to transport and install stone slabs, wooden panels and metal plates. The southern German company proved this in a project in Eichberg in the Swiss canton of St. Gallen where they clad the living room of a villa with 400kg stone slabs. The uneven structure of the natural stone and positioning of the slabs right under the pitched roof made this a challenging project.


To make sure the project went off without a hitch, the manager at the Swiss Heavydrive branch visited the construction site first to get a clear idea. The MRK 86.0 mini crawler crane with a 3-axle overhead manipulator was chosen as the optimal solution for the tricky assembly of the stone slabs. The crane has a lifting capacity of up to 2,800kg, and its non-marking tracks and hybrid operation make the MRK perfect for indoor assembly.


Heavydrive also designed a special fixture for the crane’s overhead manipulator so that the heavy stone slabs could be picked up safely. The heavy-load assembly jig with a lifting height of up to 11m accurately guided the slabs under the pitched roof into the designated position. A professional Heavydrive employee operated the crane. Within two weeks, all of the stone slabs were in place.


As well as a large range of standard suction devices and cranes, Heavydrive also develops custom assembly solutions for customers. Devices can be adapted to specific situations in no time at the company’s workshop.

In addition to its broad range of standard suction systems and cranes, Heavydrive also develops customised assembly solutions. In the company's own workshop, the devices can be adapted to a construction site's conditions within a very short time.


Swiss customers can get advice directly from the experts at the Heavydrive branch in Urtenen-Schönbühl. Additionally, the on-site vehicle and rental fleet guarantees reliable and fast equipment delivery within Switzerland. Even during the coronavirus crisis, the Heavydrive team was able to ensure smooth deployment by transporting equipment from its Swiss warehouse to construction sites without delays, despite border closures and restrictions on the international movement of goods.
