Components, systems, and services for hydraulic excavators
HYDAC: an expert partner in excavator application system solutions.
Excavator challenges
The development of modern machinery is characterised by shared requirements across various excavator sizes.
In this context, machine operators are supported, and the work process is optimised with the aid of modern electronic assistance and visualisation systems.
Excavator regulatory framework changes
Changes to the regulatory framework have resulted in increased investment in the functional safety of machines and further development of the drive and control systems of the excavators.
Emerging markets are taking up EU and US exhaust emissions regulations as well as new standards introduced in these countries.

HYDAC's contribution to overcoming excavator challenges
HYDAC offers a variety of components and systems that meet these requirements and fulfil customer demands.
In addition to standard components, HYDAC offers a comprehensive modular system designed for excavator applications.
Furthermore, it is well within its capability to develop a customised solution for a device.
HYDAC excavator technology
HYDAC development team and application engineers are working continuously to further develop products. The focus of these developments is on the following key topics:
Increases in:
- Excavation and digging performance (digging forces and breakout forces)
- The use of energy-efficient pumps and valve technology, optimal positioning in working position with sensitive controls, accurate repeatability for automatic and control functions
- Corrosion resistance owing to surface coating and special materials
Reduction in:
- Piping and installation expenditure due to combined hydraulic function units
- Noise emissions and power consumption through regulated fan speeds
- Driver exposure to dust due to cabin ventilation systems
- Hydraulic oil tank sizes by optimizing air separation in hydraulic oil, proven through simulation and testing
- Installation space, component weight and electrical power requirement by reducing solenoid valve sizes
- Learning curve of the drivers through intelligent control and visualisation systems
- Software development time by using tested and certified software libraries
- Development times by means of HYDAC modular systems and industry know-how
- Assembly times through control technology tailored to customer specifications
Extension of:
- Maintenance intervals by monitoring the hydraulic oil quality
