DYWIDAG-Systems International (DSI) agreed to acquire “OneStep” mining bolt assets from Hilti

July 23rd 2015. DSI signed an agreement to acquire Intellectual Property and manufacturing assets for the “OneStep” mining bolt from Hilti AG, Schaan/Liechtenstein.

OneStep is a self-drilling mining bolt which combines the drill head, drill steel, bolt and adhesive resin in a single unit. It offers a unique value proposition since drilling the hole, retracting the drill steel, resin capsule insertion, bolt insertion and setting of the bolt can be done in one single step. Main advantages are faster installation time, better installation quality and improved safety.

The OneStep Bolt was introduced to the German Mining industry in 2004 by Hilti AG to achieve quicker and consistent bolt cycle times for roadway development in deep level coal mining. After successfully implementing the OneStep in Germany, Hilti successfully introduced this technology in other markets including Australia, Czech Republic, Poland and the United States. Today, the OneStep is predominately used in Australian coal mines.

Patrik Nolåker, DSI Group CEO, comments: “OneStep represents an important addition to our product portfolio targeting the premium bolt segment. The product offers a unique value proposition and has proven itself by significantly increasing productivity with several customers. Our plan is to optimize the supply chain of the product and promote OneStep through our well established distribution network. This acquisition confirms DSI’s continuous interest in technically advanced solutions to make Underground Mining safer and more efficient.”
