In diploma thesis a device for determination of static coefficient of friction was developed. First the diploma thesis discusses problem and then defines goals. We examined devices and their technical characteristics and also standards for measuring the coefficient of friction. A review of the requirements for freight transport has been carried out. Additionally, critical parts of the transformer were identified. We created several different variants of the device, but in the end, we decided for the best rated device. Due to the requirement for a stable device we performed static calculations. First technical documentation for the device was created. Then, the device was produced. Additionally, we have analyzed how the friction force affected on the transformer attachment characteristics.
