About us

Deilmann-Haniel Mining Systems GmbH (dhms) is a globally active manufacturer of machinery for mining, shaft sinking, tunnel construction and for the iron and steel industry.

With a company history that can be traced back more than 125 years dhms has developed from a repairs and steel construction business into a fully independent manufacturer of high quality industrial equipment and complete machine systems. Thereby individual engineering services are a particular strength of dhms. A team of more than thirty engineers and technicians is constantly working on the design of new machines and the development of our established product range.

Success on the domestic and international markets has meant that dhms products are now being used to good effect in all five continents. The efficiency and build quality of our machines have been tried and tested at mines and construction sites under the most severe operating conditions.

The dhms range of products is based on technical experience gained of many years, combined with a strategy of ongoing innovation and development. As a machinery and equipment manufacturer, dhms sees its primary objective in providing an efficient and reliable service to its customer base. The developed machines, technical systems and processes are all geared to meet the needs of the customers and to enhance the productivity and safety of their operations.

dhms is supplying state-of-the-art products, tailor-made solutions and services. Quality is the key to the dhms success – everything produced is designed for high operational availability, durability and efficiency. dhms is committed to flexibility and punctuality in delivery schedules. All machines and equipment undergo a strict quality control process prior to leaving the factory. dhms is accredited to DIN EN ISO 9001:2015.

dhms has access to the most modern production facilities. These are used not only for manufacturing the company’s own products but also for carrying out contract work and repairs for external clients. The experience and high skill level of the 300 dhms workforce, many of whom have passed through the company’s own trainee workshops, ensures that all products and services are delivered on time and to the highest quality standards. Experienced technicians are available worldwide for the assembly of machines and equipment on site and can also undertake maintenance and repair work as well as technical training. Well-stocked spares departments ensure short turn-round times for replacement parts worldwide.

In recent years the company’s core product range of drill rigs, loaders, excavators and shaft sinking equipment has been continuously extended as a result of technical innovation. This includes the introduction of a new roadheader family in 2010 that has made dhms a recognised solution provider for both types of roadway development – drilling-blasting and mechanised cutting. The dhms engineering team is also available for individual plant engineering, e. g. design, manufacturing and assembly of hydraulic taphole machinery for blast furnaces.
