Problem

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

The problem with hard ground: particularly high forces act on all parts of the road core drilling machine. These must have a certain strength to be able to withstand the forces. At the same time, however, there are also other challenges: since 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 were lightweight. The customer also attached particular importance to ensuring that all components were as maintenance-free as possible.

Solution

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

Furthermore, to ensure the high strength and withstand the high forces acting on the component, a SHTC lead screw module was used for the installed axis. This belongs to the Heavy Duty series and was specially designed to withstand extremely high loads. Of course, all igus® components used are maintenance-free and free of external lubrication.

The collaboration with igus® also convinced the customer. A salesman was always there personally for the customer and was able to provide prompt advice on site.
