Wheel loader technology

Expert wheel loader system solutions


HYDAC offers a wide range of sector-specific components and systems for use in wheel loader applications from hydraulics, cooling and electronic to software, and control technology.

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



Wheel loader challenges

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

Ever more complex open-loop and closed-loop control processes go hand-in-hand with improved machine productivity and efficiency.

Machine operators are supported, and the work process is optimised in this context with the aid of modern electronic assistance and visualisation systems.

Regulatory framework challenges

Changes to the regulatory framework result in increased investment in the functional safety of machines and further development of wheel loader drive and control systems.

In addition, emerging markets worldwide are taking up EU and US exhaust emissions regulations while simultaneously introducing new standards.


HYDAC’s contribution to wheel loaders

HYDAC offers a variety of components and systems that meet wheel loader requirements and fulfil customer demands.

The company’s contribution encompassed standard components to a comprehensive modular system designed for wheel loader applications, a HYDAC spokesperson highlights.

“And HYDAC’s contribution includes working with the customer to develop a customised solution,” the spokesperson says.


Wheel loader technology

HYDAC’s development team and application engineers work continuously to further develop products. The results are as follows.

HYDAC wheel loader technology results in improved:

  • Excavation and digging performance (high tearing and breakaway forces). This is the result of using energy-efficient pumps and valve technology; optimal positioning in working position with sensitive controls; and accurate repeatability for automatic and control functions.
  • Corrosion resistance owing to surface coating and special materials.

HYDAC wheel loader technology results in reduced:

  • 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 requirement through reduced solenoid valve sizes.
  • *Driver learning curve 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.

HYDAC wheel loader technology results in extended:

  • Maintenance intervals by monitoring hydraulic oil quality.
