Drill rig technology

Foundation engineering and drill rig system solutions


HYDAC offers a variety of components, systems, and services to meet contemporary requirements of drill rigs.

In addition, it offers a comprehensive modular system designed for drilling machine applications.

The company’s modus operandi is to work with the customer to develop a customised solution.



Drill rig challenges

The development of modern machinery is characterised by shared requirements across the various drilling machine classes.

Increasingly complex control and regulation processes go hand-in-hand with greater machine productivity and efficiency.

Machine operators are aided by modern electronic assistance and visualisation systems and the work process is optimised.

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

As is also the case with the EU and US exhaust emissions regulations, the emerging markets in the rest of the world are taking up these standards and introducing new standards at the same time.

HYDAC understands the complexity surrounding drill rigs and is well equipped to fulfil customer demands at every turn, highlights a HYDAC spokesperson.


Advantages of HYDAC drill rig technology

HYDAC’s development team and application engineers are working continuously to further develop products.

HYDAC technology leads to improved:

Drilling performance

This is due to the use of energy-efficient pumps and valve technology, optimal positioning of the drill mast in working position with sensitive controls, and accurate repeatability for automatic and control functions

Corrosion resistance owing to surface coating and special materials

HYDAC technology leads to 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 by reducing 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 technology leads to extended:

Maintenance intervals by monitoring hydraulic oil quality
