The graduation essay has been carried out in co-operation with Kalmar Industries in Lidhult, Sweden. The purpose of our essay was to develop a complete construction solution on a hoist that could lift a laying wheel, lift it up and then turn it 90 degrees. After that the wheel shall be placed in a special holder.The background of the essay is a record of reports of damage wheels when they been incorrect lifted with a forklift. The hoist shall be used together with the same forklifts that manage the wheels today. Together with our instructor at Kalmar Industries we developed a requirement specification and from that we got free hands.However this was not the main task from the beginning, then a simular hoist should be develop but used directly in the assembly workshop without using a forklift.We started to find principle solutions that later was evaluated against the requirement specification.
Styrkan i OEE som arbetsmetod
The E-department at GETRAG All Wheel Drive in Köping have problems with the efficiency on parts of their production equipment. The equipment with the most significant efficiency problems are four automated multifunctional production cells that produces housing for rear drive units. The major part of the problem is the large amount of small stops that causes the low efficiency.The department already worked with logging of interruptions and efficiency calculations before this project started. However this work was not done to the extent considered necessary for a systematic follow-up of the interruptions.The aim of this paper is to point out a more effective and systematic way to work with logging of interruptions and the follow-up. In addition the equipment were studied with a method for efficiency calculation that ? if used properly- is a more powerful and a visually better method than the one used by the company today.As the initial current state analysis of the equipment was made a lack of documented knowledge about the equipment was discovered.

Our examination project has been to develop today?s existing walking frames and make them more exiting and user friendly for tomorrow?s users.The use of a walking frame today makes it easier for a person with a movement difficulty in different extent. It makes it easier with their living condition and the user get a more movement easier life where they can take care of the daily chores without any help from the society or the family members.With our product we get a product that not only makes it easier for the user to get out and get forward. We help the user to get forward where they often would have difficulties to get forward. An example is where its more steeper parts where it could be more difficult to get up or down and even with more difficult foundation due to bad weather.
Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

The assembly of Heavy (L350)has just been started with an upcoming pre series.This examination paper gives recommendations of improvements and necessary modifications to rationalize the pre-assembly of boom units. Three different scenarios are presented in the paper.
Rullstolshandtag som möjliggör ögonkontakt ? ett produktutvecklingsprojekt
?Dementia is an umbrella term for several symptoms of impaired brain function. The person's behavior is affected when mental functions such as memory, attention, concentration and language are affected and the dementia patient can have difficulties to interpret sensory input. Communication is based a lot on body language. It is therefore important for the caregiver to seek eye contact with the patient in order to simplify communication and it can be of great help to show with the whole body what they mean and be able to point out things.
Snurrar läshjulet när Boksnurran stannar? En studie i hur man kan arbeta med högläsning och böcker i förskolan
The aim of this thesis is to describe how to work with the development of language by reading aloud. I have chosen to look at the reading aloud project "Boksnurran" Book Wheel to see if it has influenced the daily work with reading in preschool. My questions are: How do they work with reading in preschool? Is the reading environment suitable? How do the staff describe their booktalks? What problems do they encounter? What can be improved? The thesis is based on qualitative interviews. Those interviewed have participated in "Book Wheel".
Konstruktion av serviceutrustning till tunnelborrningsmaskin
The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.
Pressning och hantering av halm som energiråvara
I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.
Sourcingstrategier för komplexa produkter och system
Denna uppsats behandlar hur sourcingprocessen av komplexa system på Försvarets Materielverks (FMV) kan struktureras genom att undersöka parametrar som är viktiga att beakta vid outsourcing. En del av FMV:s strategi grundar sig i att minska den interna verksamheten och att lägga större åtaganden på leverantörer av systemlösningar, för att på så sätt kunna minska behovet av interna resurser. Därför blir det viktigt att besvara huruvida systemansvar bör tas av FMV eller av en leverantör.Rapporten behandlar processen om att fatta ett beslut om make-or-buy och när och varför det är motiverat att överlåta systemansvar till leverantörer. McIvors modell om outsourcing används för att besvara frågan hur FMV bör fatta ett beslut rörande make-or-buy genom att modellen tillämpas på tre pågående projekt. Därefter används "the strategic supply wheel" för att bedöma vilka parametrar som är viktiga att uppfylla både internt och externt vid outsourcing av aktiviteter beroende på om tid, kostnad eller kvalitet är prioriterat i respektive projekt.
Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64
The report comprises two separate parts:part 1: Temperature needs for district heating in the paint shop for axles in building 210part 2: Energy and low temperature waste heat solutions in heating and cooling systems for building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.
