Compact integrated electro-hydraulic solutions provide plug-and-play installation and control

  • Innovative solution combines hydraulics with drive control in one compact linear actuator
  • Integrated oil reservoir reduces on-site space as no separate power unit and oil tank are required
  • Closed-loop system ensures high efficiency

Bosch Rexroth, the leading company in drive and control solutions, has introduced a new system concept of electro-hydraulic drives targeted at large civil engineering and infrastructure projects, such as ship locks and movable bridges. The innovative system features a compact hydraulic cylinder with integrated servo-hydraulics.

The new actuators use a closed loop system, which means that there is no need for large oil storage reservoirs at the site, often a significant factor in civil engineering or industrial projects. This has the additional benefit that the systems can fully tested before delivery, significantly reducing testing and commissioning onsite. The hydraulic cylinders are also very resilient to sudden shocks or external loads, such as those caused by a ship moving into and through a ship lock.

“This solution draws on closed-loop hydraulic systems that we developed for the offshore market. By combining those with our proven drive technologies, we have developed an innovative solution that addresses the needs of the civil and infrastructure markets,“ said Ron Van den Oetelaar, Vice President Business Unit Large Projects at Bosch Rexroth.

The new systems bring together proven technologies from six different Bosch Rexroth divisions including the closed loop hydraulic cylinders, the electric drivers, power units and the control systems. The latter can be installed separately in their own cabinets or integrated with the overall operating or control system for the project.

Additionally, the system can include sensors that monitor oil quality, temperature, etc. This allows for remote monitoring of the systems and enables predictive maintenance, as the operator can see if there is an issue developing and schedule maintenance outside of normal operating hours.

“These smart electro-hydraulic cylinders are the missing link in smart infrastructure systems.“ said Mr. Van den Oetelaar. “They bring the reliability of Bosch Rexroth’s hydraulic cylinders to the market in a simple plug-and-play solution.”
