As a result of constantly rising energy prices, alternative heating systems are increasing in popularity. The ever-growing idea of environmental protection also contributes to the fact that there has been a real boom in heating systems operated with renewable energies. A good part of this boom is concentrated on all types of heat pumps and here in particular on geothermal heat pumps with deep probes. The increased need for deep drilling resulting from this boom is leading to long waiting times and high costs due to the small number of drilling providers for earth drilling. To increase the supply of geothermal drilling on the market and thus reduce the waiting times and the costs for a geothermal drilling, more earth drilling machines are required, and the overall number of providers must also be increased. To make it easier for inexperienced earthwork companies, such as installers, to enter the earth drilling market, a new type of earth drilling machine was developed in the course of this work. This drilling machine is equipped with an electro-hydraulic and software-supported control to make operation as easy as possible for inexperienced operators. To be able to write the software with well-founded data, a Matlab script for calculating the requirements of the ground on the drilling machine was also written in the course of this work, which is to be further developed into a separate software application. The developed drilling machine is smaller, lighter and above all cheaper than the drilling machines available on the market. To be able to compete with the large drills despite the small dimensions that are aimed for in the drill, the performance requirements were defined in advance before the development of the individual assemblies. These requirements roughly correspond to those of the large drills. Accompanying the constructive development with the 3D-CAD program Solid-Edge, the individual components and assemblies were also simulated by the author of this work with the FEM simulation program contained in the CAD program. In the first stage of development, a few parts of the drill were intended to be purchased from external suppliers. During development, several optimization steps were carried out, as problems arose due to external influences which were not foreseeable in advance. As a result of these problems, more and more assemblies were developed in-house over the development stages. A clear advantage of this progressive in-house development was that the weight-saving measures could be intensified, and the total weight of the drill could be reduced to almost 1,500 kg. Attention was also paid to the transport logistics, which were refined to such an extent that the drilling machine can only be transported with a car and a single-axle trailer attached to it. For this car-trailer combination, the operator only needs a class E to B driver's license. Any restrictions associated with transport by truck have thus been circumvented. Many considerations were also made for safety technology to the operator and the surrounding people, to reduce safety risks during operation as far as possible. For this reason, constructive measures to avoid hazards were already integrated during construction. After the development was completed, further measures were taken in the software of the controller to avoid possible hazards. After completing several test drillings with the drilling machine, it is planned to carry out a CE certification of the machine. After that, the machine is to be built in series and sold. For this reason, care was taken right from the design stage to ensure that both manufacture and assembly can be carried out quickly, easily, and inexpensively.
