Used machines

Reliable alternatives if the project conditions fit

Used machines from Herrenknecht are a reliable alternative to purchasing a new one if the project conditions fit.

________________ Used tunnel boring machines from Herrenknecht are a reliable and cost-efficient alternative to purchasing a new TBM – if the project circumstances fit. If ground conditions and the machine technology match and if the profile diameter is more or less the same, a used and completely refurbished TBM can render the same good performances as a new tunnel boring machine.

This also applies to any additional equipment such as separation plants, control containers, jacking frames, emergency power systems, transformers, compressors, ventilation equipment or slurry pumps.

Fit for the next mission in only two steps

In principle, both the smallest microtunnelling machines and TBMs with largest diameters can be refurbished and made fit for the next project. Herrenknecht can provide used tunnel boring machines and additional equipment in almost all diameter ranges. After buyback, the original functional state of the machine is restored in a first step and adapted to new requirements, if necessary. In a second step, professional and experienced engineers and technicians carry out a complete quality test in line with Herrenknecht standards. High-quality refurbished machines that are tested with extensive know-how are then ready for a new mission.

Quality of new products pays off

Highest technical and quality standards of the new product and the modular design of the machines are basic requirements for their reusability. All Herrenknecht TBMs meet these conditions in full. Refurbished and reused machines reduce costs and energy consumption and thus contribute to sustainable resources management.

Used machines with quality seal

The “Herrenknecht Approved” certificate provides additional security when buying used Microtunnelling Machines, HDD Rigs and related containers and power packs. The seal is given to used machines after they have been thoroughly checked in line with proven Herrenknecht quality and the original functional state has been restored. The 9-month warranty period documents the full functionality of all used machines from Herrenknecht carrying the “Approved” seal.
