Using the ReLog to detect & measure impacts on mine hoists
Boliden, a leading mining and smelting company based in Sweden, uses something called ‘mine hoists’ in their mines to transport raw materials from the mines up to the surface. These cages act as shaft conveyors for transporting gathered material 900 m to the surface and are usually completely autonomous.
Unfortunately, Boliden has noticed that the guidance system of the mine hoist has been pushed sideways which has caused unnecessary wear on the guidance system. By using the ReLog to measure vibrations on the cages, Boliden expected to learn where the sideways displacement is at its largest so correct measures can be taken.
Oscar Lindgren, Project manager of Plant engineering, realised that Boliden could use the ReLog S to record and hence detect the vibrations created by the misaligned guidance system. With this information, Oscar and his colleagues could understand where the displacement is at its largest and quickly take actions to ensure that the hoist and the shaft remains undamaged.
“The ease-of-use of the ReLog S and the ability to quickly analyse the vibrations in VibInspect was crucial to us and enabled quick tests and immediate feedback” – Oscar Lindgren

ReLog Vibration data logger
The ideal vibration data logger for capturing and monitoring vibrations, shocks, and impacts. With superior battery life and up to 128 GB of memory, the ReLog is the perfect tool for monitoring vibrations in most environments. It has been designed to be extremely easy to handle and by the touch of a button, you will be up and running and measuring with up to 32,000 Hz sampling rate.
With its waterproof housing (IP67) there really are very few limitations to where you can use the ReLog! And when you’re done measuring the included software will make sure you have perfectly structured files that are easy to analyze and work with.
