One Equity Partners To Buy Montanhydraulik

By Amit Chowdhry • Dec 23, 2025

One Equity Partners said it has signed a definitive agreement to acquire Montanhydraulik GmbH, a Germany-based industrial engineering and manufacturing specialist focused on ultra-large-scale hydraulic cylinders, aggregates, and complete hydraulic systems, along with related global maintenance and repair services. Financial terms of the private transaction were not disclosed.

Founded in 1952 and headquartered in Holzwickede, Germany, Montanhydraulik provides customized hydraulic cylinder solutions used in demanding, heavy-duty applications across sectors, including infrastructure, electric grid, mining, hydropower, wind, and mobile cranes. The company employs more than 1,100 people across 10 locations worldwide.

OEP said the acquisition thesis centers on expanding Montanhydraulik’s geographic reach and capabilities through an M&A-driven strategy, including integrating complementary businesses, improving efficiency, and extending the company’s footprint into adjacent sectors. The firm also pointed to macro tailwinds including infrastructure modernization, rising energy demand, and the shift toward renewables, while identifying the U.S. as an attractive growth market alongside further density in core European markets.

Montanhydraulik said the partnership is expected to build on its existing strengths and support new product initiatives and expansion in priority global regions, leveraging OEP’s industrial experience and track record executing strategic acquisitions.
