Resignations are common in all business sectors and can also be found among forest Machine operators in the forest business. As the industry today faces a lack of forest Machine operators it is justified to determine why Machine operators choose to quit their jobs. The aim of this study was to a) find out the number of Machine operators that have resigned b) identify and analyse the cause for these resignations c) identify the reasons why the Machine operators started to work in the forest and d) give suggestions on different measures that will limit resignations amongst forest Machine operators. A questionnaire was sent to Machine operators who have quit working as employees, contractors or as employees for contractors with Holmen Skog during 2003-2007. 32 Machine operators responded to the questionnaire. Interviews were made with 10 Machine operators who had answered the questionnaire to gather more qualitative data. The results of the study indicate that fewer forest Machine operators change profession than employees in other occupations in Sweden.

Utvärdering av traktplanering på Holmen Skog

This study has been performed with the help of forest Machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the Machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding Machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding Machine operators thought so. Over 40 % of the responding Machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

Avsättningar i pappersmaskiner : Utbildning och förslag till processförbättringar

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among Machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with Machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for Machine operators.The education about deposits for Machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the Machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

Volymsrapportering vid drivningsarbete

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 Machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the Machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft

The scarcity of qualified forest Machine operators as well as the increased competition for competent Machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest Machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active Machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.

Operatörsunderhåll : Ett examensarbete om att använda 5S till hjälp för att förbättra operatörsunderhållet

As the final course in the education ?University Diploma Programme for Process Operators? there is a thesis in cooperation with a company required.This thesis is about operator maintenance and 5S made at Metsä Board in Husum.In this report you can read my opinions and conclusions based on literature studies and the interviews that have been made with the staff at PM6 (the paper machine).I chose to focus on the theory of lean, 5S and operator maintenance because it covers the area of this thesis.The operators shall do their rounds to make sure that the equipment works fine. They shall also write down things that they notice in a checklist. This is not done as it should be and the question is: can this be solved by using 5S?My conclusion of this thesis are:Better review of the task so that everyone is involved.

Vad skapar stress respektive trivsel hos avverkningslag? : en jämförelse mellan bolags- och entreprenörslag

As a student during my studies, I have been told about entrepreneurs who have red numbers in their financial statements, and there is a forest machine operator shortage in Sweden. The basic idea of this thesis was to examine the underlying factors that may have caused the problems described above. The aim of this thesis was to investigate the factors that create stress and job satisfaction as a forest machine operator. The study was performed as a comparison between forest companies own harvesting teams and entrepreneur teams to investigate if there are any differences in stress and job satisfaction between the two different types of team. The study was conducted in collaboration with SCA Skog. The material for this study was collected by doing interviews with SCA's harvesting teams. A total of 27 forest Machine operators were interviewed, divided into a total of 10 separate harvesting teams. It was very similar between the different type of teams, which situations the operators experienced stress.

Konstruktion och utformning av skydd till spolverk

This thesis has been carried out in cooperation with Burseryds Bruk AB.Burseryds Bruk is a company that manufactures steel strapping. The thesis isabout developing a concept of protection that should be used to protect theoperators from the rotating parts of the machinery lines. The aim of the projectwas to improve work safety for operators working at the machines by producing aconcept for a protective device. The project's first part was based on ergonomic data collection methods tounderstand the operations performed on the machine and the hazard occurringduring the process. The methods used to collect data were, interviews,observations and questionnaires with the operators of the company. This was thenused to make the ergonomic analyzes hierarchical task analysis and link analysis. The data collected from the company's operators was used create 10 conceptswhich were then evaluated.

(overall equipment efficacy) should be illuminated and analyzed. The theory of ?Single Minute Exchange of Die? is also presented.The method used in this project is mostly based on qualitative studies but also quantitative studies are presented.

Markering och risning av basvägar inom slutavverkningstrakter : en intervjustudie hos maskinförare och planerare

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Varför slutar markberedningsförare?

The purpose of this study is to seek answers to an ongoing problem in the forest sector; why scarifying operators quit their job. Scarification quality is crucial for successful reforestation after clear felling. It is therefore important to keep good operators working in the business. To collect the desirable information interviews were made both with contractors who are working and operators who have stopped working with scarifying. The conclusion one can draw from this report is that the scarifying operator job needs improvement in multiple areas. The former operators are mostly dissatisfied with the stress, low wages and negative physical effects that this work brings..

Realisering av en modulär skogsmaskin - En skalmodell

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the Machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

Förbättring av utnyttjandegrad i robotcell

When a company in the manufactory industry makes costly investments, it's important that these are used as much as possible. The company in this case claims that their invested robot cell, with CNC machine isn't used enough. The questions here are: How can we improve the use of the robot cell? Which products are appropriate for the production in the robot cell? As a method to come to a conclusion, an analysis has been made over the manufactured products. And also interviews with Machine operators and the production management.

Självgående renslastare till sockerbetor :

Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to write about something new in this sector. We heard that a new concept had come to Sweden so we wanted to find out everything about this machine. This new technique was a self-propelled cleaning loader for sugarbeets. This machine is supposed to replace a loader and a cleaning machine when the sugarbeets is going to be loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the sugarbeets with rollers from the pile, which is placed close to the road.
