Problem

infraTest Prüftechnik GmbH has developed a road core drilling machine that can take samples from roads and runways that have a concrete or asphalt surface. The samples are drilled out using diamond core bits and subsequently analysed.

The problem with hard soils is that particularly high forces act on all parts of the road core drilling machine. These must therefore be particularly stable in order to withstand the forces. At the same time, however, there are other challenges: As the drilling rig is designed like a compact trailer and is portable, it was also important that the installed components had a compact design and therefore a low weight. The customer also attached particular importance to all components being as maintenance-free as possible.

Solution

With the help of igus® components, infraTest Prüftechnik GmbH developed a road core drilling machine that was able to withstand all of the customer's challenges. Spindle axes from the SLW series and small micro energy chains were used.

Furthermore, an SHTC spindle module was used for the installed axis to ensure particularly high stability and the high forces acting on the component. This belongs to the Heavy Duty series and has been specially designed to withstand particularly high loads. It goes without saying that all igus® components used are maintenance-free and free from external lubrication.

The cooperation with igus® also impressed the customer. A sales representative was always personally available for the customer and was able to provide prompt advice on site.
