Abstract [en]

The purpose of this thesis is to identify and investigate reference times for regularmaintenance work activities at the department responsible for maintenance ofunderground loaders at company LKAB:s mine in Kiruna, Sweden. The study is athesis of 15 credits at Uppsala University and has been carried out over 10 weeksduring the spring 2016. The majority of the work has been carried out on site.

For a long time the underground loaders department has been struggling withrecurring breakdowns. Which affect the production in the mine and is a burden forthe maintenance personal. To live up to the expectations of the customer and be ableto plan the work procedures with better precision the department now wants to geta better picture of how much the planning of the maintenance work affects thedepartment, both in time and costs. The goal with the study is to proposeimprovements of how to minimize the time for maintenance work.

The study has looked at internal statistics from 2015 and used it to map out whichactivities that have the biggest influence on the department. The first selectionresulted in six procedures which are carried out on the two types of loaders from SANDVIK that the company uses. The chosen activities are bucket replacement, tiltcylinder replacement, lift cylinder replacement and front and rear axle replacement.Due to the limitation of time for the study one of these six activities were chosen fora deeper analysis. The choice, after discussion with the mentor Sandy Doull at LKAB,fell on front and rear axle replacement.

The conclusion after the study is that there are big opportunities for improvementsfor the department responsible for the underground loaders at LKAB. Workingactively with follow ups and implementing the Lean tool 5S they can reduce waste,variation and to improve productivity for all the work procedures. Improvements thatcould lead to big economic profits by reducing downtime in production and improveworking conditions for maintenance personal during the work procedures.
