How the eOC works

The eOC pump – the central component

The eOC pump – the central component

The electrohydraulic eOC pump with swivel angle sensor and pressure sensors is the central component in the eOC architecture. It ensures the proper control of the necessary setpoint values for torque, pressure or flow. The pump provides highly dynamic control with millisecond accuracy to modulate the pressure. In combination with the eOC software, characteristics such as dynamics and power control can be set, changed and combined.

eOC software for machine optimization

eOC software for machine optimization

Controlled via a CAN interface, the eOC software makes it possible to set various control parameters flexibly during operation. Control modes can be individually changed and combined during operation and the pump dynamics can be set variably. Pressure, torque, flow and the swivel angle are controlled independently of each other in an electronically closed control circuit.

The eOC software can be installed on a Rexroth BODAS controller. The software constantly adapts the hydraulic power to the available engine torque and allows dynamic, precise work functions, increasing the overall productivity of the working machine, and optimizing energy consumption.

The eOC architecture allows a new approach when it comes to the travel drive systems of compact machines.

Travel drive in focus

The eOC architecture allows a new approach when it comes to the travel drive systems of compact machines. The eOC functions in accordance with the secondary control concept, combining the functionality of a closed-circuit travel drive with the physical layout of an open-circuit drive, which only requires one pump for travel and working functions.

The eOC travel concept requires fewer components in the machine and simplifies the hydraulic architecture. Complexity in the hydraulic system is moved into the software. Travel direction valves and brake valves are no longer needed.
