WMH Herion supplies you with the complete range: from rack technology for tracking systems and bevel gear units through to corrosion-resistant custom solutions for outdoor use. Standard parts from stock, custom production made to measure. ## Challenges in renewable energies Renewable energy plants have to operate reliably for many years under extreme outdoor conditions without intensive maintenance. Solar trackers, wind turbines and hydropower turbines use drive components that withstand weather, UV radiation, salt air and temperature fluctuations. The availability of the plant is directly linked to its yield, which is why failures must be minimised. At the same time, cost efficiency is a focus: components must offer an optimal ratio of performance, service life and price. Standardisation and modularity of the drive elements considerably reduce operating and maintenance costs. WMH Herion supplies racks and rack and pinion drives for solar tracker systems that work precisely and reliably even with large temperature fluctuations and under corrosive loads. Galvanised and coated versions as well as variants in stainless steel are part of the range. Bevel gear units from WMH Herion transmit the movement in solar and wind power plants efficiently and with low maintenance. The broad stock programme ensures that spare parts and replacement components are quickly available in order to minimise downtimes when servicing is required. ## Precise drive technology for renewable energies⁠: catalogue products For renewable energies, WMH Herion supplies racks in straight and helical toothed versions with corrosion protection, bevel gear units for angular transmissions and robust drive elements for weather-resistant outdoor applications. Galvanised and coated variants are available from stock.

Our technical sales team advises you on selection and design, directly and without detours. Contact us ## WMH Herion for renewable energies What distinguishes WMH Herion as a partner? Renewable energy plants depend on drive components that function reliably over long operating periods without frequent maintenance work, whether in wind turbine auxiliary systems, tracking systems for solar modules or pumps in bioenergy plants. WMH Herion supplies spur gears, gear units and couplings that meet these requirements for service life and robustness, from the stock programme and from custom production. The close coordination between engineering and sales at WMH Herion means for you: fast technical clarification of design questions, transparent material selection and reliable delivery. ISO 9001 certified, with experience in renewable energies and more than 40 further industries worldwide. Which racks are suitable for solar tracker systems in outdoor use? For solar trackers, hot-dip galvanised or coated racks from the WMH Herion range are recommended, as they are permanently protected against weather and corrosion. In combination with matching pinions and planetary gear units, they form compact, low-maintenance drive systems for tracking. Are corrosion-resistant drive components available for offshore wind applications? Yes. WMH Herion supplies drive components in stainless steel versions and with special coatings for corrosive environments such as offshore applications. On request, material certificates and test certificates are supplied for documentation. Does WMH Herion also supply complete assemblies? Yes. In addition to individual components, we offer assembled handling axes and complex multi-axis systems, fully assembled, tested and ready for use. How quickly are standard items available? Most items from the stock programme are available immediately and are delivered within a few working days. For custom-made solutions, we discuss the delivery time individually. ## Products for renewable energies [![](https://wmh-herion.de/wp-content/uploads/2026/06/1-2-313x214.avif) ### Rack technology](https://wmh-herion.de/en/drive-technology) [![](https://wmh-herion.de/wp-content/uploads/2026/06/2-2-320x203.avif) ### Drive elements](https://wmh-herion.de/en/drive-technology) [![](https://wmh-herion.de/wp-content/uploads/2026/06/3-2-258x214.avif) ### Gears](https://wmh-herion.de/en/drive-technology) [![](https://wmh-herion.de/wp-content/uploads/2026/06/4-2-320x208.avif) ### Assemblies and handling tasks](https://wmh-herion.de/en/drive-technology) ## Your contact with us ### Hotline Enquiries [+49 8442 9699-245](tel:+4984429699245) Mon – Thu 7:00 – 17:00 Fri 7:00 – 13:00 [anfrage@wmh-herion.de (opens your e-mail application)](mailto:anfrage@wmh-herion.de) ### Hotline Orders [+49 8442 9699-250](tel:+4984429699250) Mon – Thu 7:00 – 17:00 Fri 7:00 – 13:00 [bestellung@wmh-herion.de (opens your e-mail application)](mailto:bestellung@wmh-herion.de)
