Electro-Hydraulic Pump System reduces fuel costs on high-power lifting applications

The new integrated solution provides the opportunity to realise fuel cost savings of up to 50% and gives the potential for customers to downsize or remove the diesel engine, therefore creating an optimised, highly-efficient, completely electric vehicle.

There is a huge shift towards electrification across many areas of industry and society delivering environmental and sustainability as well as performance benefits. As a result, large numbers of OEMs are looking to tap into the technology which also supports improved maintainability, greater safety, and compliance with increasingly stringent emissions regulations.

Conventional solutions in this area work with coupled power distribution, where the engine is sized for peak demand with no energy storage or recovery capability. In addition, the efficiency (torque/speed operation) of the internal combustion engine (ICE) tends to be low.

With its EHPS, Parker has addressed a market need for decoupled loads and power distribution. This design concept facilitates far better engine management whereby energy storage and recovery functions can be introduced. With its separate drive train, the EHPS also offers high ICE efficiency via power point operation.

Parker’s system solution comprises motor and pump technology to recover energy while materials are being lowered – all controlled by a power inverter. Embedded Parker-derived software provides the system function and operational interface, while peripheral manifolds and system components deliver functionality to key services throughout the wider hydraulic system.
