Excavator technology

Components, systems and services for hydraulic excavators

HYDAC offers a wide range of industry-specific components and systems from hydraulics, cooling, electronics, and control technology to standard products for use in various excavator applications.

Intelligent integration of products creates innovative and technologically advanced subsystems and complete systems for the increased requirements of specialist machinery.


System intelligence for hydraulic excavators

Modern machines require a variety of assistance and control systems wherever simpler operating concepts and a better overview and controllability of machine functions become necessary.

HYDAC’s electro-hydraulic system solutions act as an interface between actuators and sensors.


Hydraulic excavator challenges

The development of modern machinery is characterised by shared requirements across various excavator sizes. 

Changes to the regulatory framework have also resulted in increased investment in functional machine safety and further development of excavator drive and control systems. 


HYDAC’s offering to overcome excavator challenges

In this context, HYDAC supports machine operators and optimises the work process through use of modern electronic assistance and visualisation systems. 

In addition to supplying standard components, HYDAC offers a comprehensive modular system designed for excavator applications and their ever-increasing requirements. 

HYDAC also works in partnership with customers to develop customised solutions for devices and the company’s development team and application engineers work continuously to further develop products, with focus on the following key topics.

HYDAC excavator technology

​​HYDAC excavator technology leads to increases in:

  • excavation and digging performance or digging forces and breakout forces (the use of energy-efficient pumps and valve technology, optimal positioning in working position with sensitive controls, and accurate repeatability for automatic and control functions); and
  • corrosion resistance owing to surface coating and special materials.

Concomitantly a reduction is found 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 optimising air separation in hydraulic oil, proven through simulation and testing;
  • installation space, component weight and electrical power through reduced solenoid valve sizes; and
  • driver’s learning curve through intelligent control and visualisation systems;
  • software development time by using tested and certified software libraries;
  • development times by means of HYDAC’s modular systems and industry know-how; and *assembly times through control technology tailored to customer specifications.
