    This is us - Our new corporate video

    Two days of shooting, the active participation of our EURODRILL team (including ambitious staff members who appeared in the film), and rapid and effective coordination with relevant specialist departments – the production of our new promotional film was a true team effort that also led to a fantastic result! Indeed, in just three minutes, the film offers interested parties an extensive insight into the work carried out by EURODRILL GmbH, as well as a look at the people behind the scenes at the company.

    The film project began with a conceptualization and planning phase in the early part of the summer of 2022, whereby we asked ourselves the following questions: What do we want to show in the film?
    What is the best way to present who we are and what we can do? Who would be the right partner to implement this important project with? The result is a film in which EURODRILL truly presents itself for the first time. It’s a film that not only enables customers, retailers, and potential future employees to get a good look at our business premises; it also highlights our expertise, our impact on the global market, and our collaborative way of working together. Everything we captured on those two days of shooting was ready to be shown as part of our presentation at the BAUMA trade fair. As mentioned, our employees also contributed to the success of the film by helping out in so many different ways.
     

    Diagram 1
    Geroler motors versus EA 61 V - Theoretical comparison with the RH 32 X

    In diagram 1 it can be seen, simply when comparing the theoretical values, that the EA 61 V offers significantly superior performance to the Geroler motors. As well as slightly more torque and 50 % more speed, the system is particularly notable for the variable adjustment of its gears. What's more, the new drive system can be operated at 35 % higher output power, thereby making use of the installed capacity of the increasingly more powerful drilling rigs. The additional, utilizable speed/torque performance is shown in red in the diagram.

    Geroler motors versus EA 61 V – (Real-life) comparison with the RH 32 X, actual values

    So much for the theory - in real-life conditions, the advantages of this new drive system compared to Geroler motors are even more pronounced, as can be seen in diagram 2:

    1. Speed stability at the highest level of torque
    Thanks to the significantly better volumetric efficiency of the axial piston motor, there is markedly less speed loss at the highest level of torque.

    2. Higher practical torque at high speed
    Due to the higher efficiency rate of the EA 61 V and the fact that serial shifting is no longer required, the losses in top gear are significantly smaller.

    3. Higher speed at the same torque
    Where torque of 25 kNm is required, the speed available almost doubles e.g. 38 rpm instead of 20 rpm

    4. Higher torque at the same speed
    At a speed of 50 rpm, roughly 3 times the practical torque is available e.g. approx. 20 kNm instead of 7 kNm.

    Savings potential

    Due to the significantly greater efficiency (see points 1 and 2 diagram 2 above) and the greater net drilling capacity (see points 3 and 4 diagram 2 above), markedly lower drive performance is required for the EA 61 V drive system, thereby saving on fuel. By way of an example to illustrate the savings potential, EURODRILL is assuming average savings of 10 kW/h on drive performance - and this is a conservative estimate. As approx. 0.2 l of diesel is saved for each kW/h not required, a saving of some 20,000 liters of fuel is achieved over 10,000 operating hours.

    An incredible 53 tonnes of CO2 is saved as a result, which makes a huge contribution towards reducing the carbon footprint on the construction site.

    Even with higher acquisition costs the new system remains an attractive proposition, because with the documented savings payback is rapid - and at the same time, deploying the EA 61 V drive system allows the drilling rig to be operated at a higher drilling speed. The lower output required means important drilling rig components (motor, pumps and other hydraulic components) are conserved for longer. The thermal economy of the entire drilling rig is significantly improved.

    The EA 61 V drive system in action

    The latest-generation drive system is being deployed, amongst other projects, for one in Antwerp. In 2024, not far from the city center, 350 m of new quay walling is to be secured with 150 anchors in total.  The building contractor working on this project, Herbosch-Kiere (part of the EIFFAGE Group), had drilled some test anchors in advance, to make the dimensioning of later anchors easier. As the existing hydraulic hammer was not equal to the challenge of a 219 mm diameter and a drilling depth of up to 42 m, the decision was taken to deploy a EURODRILL RH 32 X using EA 61 V drive system. It had to drill through several meters of sand, followed by a thick layer of clay and finally 4 m of the infamous, extremely hard "Boomse Klei". Thanks to its high torque and powerful percussion unit, it was able to master the combination of a large drilling diameter and deep drilling depth to the full satisfaction of client Herbosch-Kiere.
