On 6.11.2019 took place a training of maintenance workers of a renowned company producing technology for mining industry. The training was focused on electronic overload units equipped with Stahl hoists. These units are primarily used to assess the overload of a given lifting technology, but at the same time, more and more functions and operating datas are integrated to simplify and increase maintenance efficiency. Last but not least, these units contain information on the remaining living life of the machine. This makes the decision of the end user much easier when he needs to decide what to do when the predicted living life is over.
