Competence & standard
of work in oil hydraulics

As the experienced expert for oil-hydraulic systems and components, we can develop and produce various hydraulic systems for any presented problem! Our project planning and development team, with particular competence in the areas of lifting and conveying engineering as well as clamping hydraulics, is specialised in tailoring projects entirely according to customer request.

systems & components

Project planning of hydraulic systems means for us the development of efficient hydraulic systems. Our customers appreciate economical hydraulic system technology as well as the individual exchangeability of the hydraulic components. We also offer reasonably priced, high quality services in all areas of hydraulics and hydraulic components.

Hydraulic units
in use

Our offer includes consultation and project planning coordinated exactly to the actual use of the hydraulic system. Our homepage, e.g. in the reference area, shows you the many versatile ways our hydraulic units are deployed. You can gain a better understanding of our range of possibilities based on the examples of our customers.

The company

Otto-Hydraulics GmbH (established 1989 as Kröll Hydrotechnik KG) develops, produces and delivers high quality hydraulic systems and components. The company provides its many years of experience as well as highly motivated and qualified employees for solving drive and conveying related tasks to its worldwide customers in mechanical and plant engineering.


We develop and design components, partial systems and complex hydraulic systems according to our customer's ideas. The latest resources, 3D design software, and comprehensive knowledge of the standard components available on the market enable us to achieve optimal results in terms of performance and costs.

Mechanical production

In our production facilities we have state-of-the-art machining centres to produce our designed control blocks - the basic elements of our systems. Block production within our own company leads to independence, economic efficiency and control over the complete manufacturing process.

Parts and system assembly

Assembly in our company is optimally geared towards individual units as well as small and medium-sized series. When hydraulic installations are installed at the customer's premises, we provide competent support.

Quality assurance

We guarantee the quality of our products by choosing high-quality components, constant monitoring and a one-hundred-percent outgoing goods inspection.

Logistics and on time delivery

Reliable suppliers, a streamlined handling organisation and friendly communication with our customers result in very high delivery reliability and on time delivery. Competent logistics partners and the provision of suitable packaging guarantee safe dispatch throughout the world; whether as air freight or ocean cargo or by land.
