This degree project has been performed with Mega Teknik AB in Landskrona. The project has resulted in a workplace for the cable installers of Mega Teknik. The workplace contains a workbench and a cart. The first stage in this project was to make an analysis of the current workplace to identify the needs the installers had. The different principle construction proposals of how the workbench would look like and which functions it would have was made during brainstorming, in groups and alone. These proposals were compared against each other using a functional analysis that has been put up to get the principle construction that fulfilled most points in this analysis. The proposal chose for further work was a cart and a bench with a module intends, the table got a formulation that creates a better reach for the installers. This proposal was generated in Catia V5 to get a better overview of the suggested proposal. During the primary structure phase drawings over all the products were made and the components were chosen. Calculations were made and the product got the dimension required. The final step was to build a full scaled model. The cart was sent to a company and the other parts were made in the university’s workshop by the student with help from others when needed. The chosen components were bought and installed. The project resulted in a fully functioning prototype and a complete series of drawings in order to produce the workplace. In the conclusion discussion about future work and pros and cons with the chosen product were made.

Epiroc Rock Drills AB in Örebro manufactures and develops machinery for the infrastructure required to maintain a fully operational mining industry, such as ventilation, drilling rigs, trucks and loaders etc. In these environmentally conscious times, a large market focus forzero emission machines has begun to emerge. By replacing today'sinternal combustion engines, mining companies can save large sums of money in ventilation costs and fuel while creating a more pleasant working environment in the mines. Due to these rapidly changing needs, Epiroc's machines must also change in design and performance. Epiroc has thus chosen to use interchangeable batteries in their new generation of mining machines. When the battery is discharged, it must be easy to replace with a fullycharged one. From an economic point of view, it is also important that the machine is always in production without any stops, making fast and efficient battery switches desirable. At present, the battery change is usually done with a mono-rail crane down the mine. This has proved to be very difficult and ineffective as the battery is too often jammed into the machine due to the fact that the machine is poorly positioned against the crane. Ceiling heightis also a problem, preferably one should have about 6-7 meters to accomplish a safe lift with the crane, which is not always possible down in a mine. In order to find a more long-term solution to this problem, this degree project took its start. During the course of the process, a number of methods in product development and concept generation have been used to develop different concepts and screen them based on the needs identified at the beginning of the work. The main problem was divided into four sub problems to facilitate conceptgeneration, the most promising sub concepts were visualized using CAD and then put together in different combinations. These combinations were then evaluated against today's solution to easily see what concept should be further developed. This resulted in a concept that consists of a separate platform,which can either be placed on a vehicle or as a stand-alone station. On this platform there are two telescopic arms, one on each side. These arms lifts the three ton heavy battery from the mining machine in an arcuate motion over a charged battery on the platform, placing it in a designated location and then lifts the charged battery into the machine. With this concept, it is also possible to accomplish a safe change with a limited ceiling height of approximately 3.5-4 meters, which is an improvement compared to today's solution.
