This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.

Linde Material Handling AB har på kort tid gått från att vara ett litet familjeföretag till att bli en av Sveriges största Truckleverantörer. Orderingången har vuxit fort men stora delar av företaget har inte riktigt följt med i utvecklingen vilket har resulterat i att de idag har problem att hålla utlovade leveranstider och att leverera produkter av rätt kvalitet.Utifrån en kartläggning av processen från det att en Truck säljs till dess att allt material finns hemma identifieras de brister och kritiska punkter som är roten till problemen. Processkartan i kombination med en nulägesbeskrivning ska ge ett antal förbättringsförslag där lösningar på problemen tas upp och analyseras.Den största bristen som identifierats i processen var främst avsaknaden av ett för företaget gemensamt planeringssystem. I dag använder olika avdelningar olika system vilka ofta består av avancerade Excelfiler och i andra fall av att information lagras i huvudet hos någon anställd. Detta i sin tur resulterar i svårigheter med uppföljning av de sålda Truckarna.

Ett Pure-Car/Truck-Carrier fartyg med kapacitet för 6000 bilar på en har prospekterats. Fartyget skall huvudsakligen gå mellan Ostasien, Europa och Nordamerika.I problemformuleringen beskrivs vilka utmaningar och förutsättningar som har varit, samt lösningsmetoder och begränsningar. Under Analys beskrivs hur tankegångarna har varit mer detaljerat och illustrerat med figurer. Analysen har i stort sett gjorts i den ordning som underrubrikerna följer. Nästan alla beräkningar är gjorda i MATLAB enligt kända metoder; många hänvisningar görs till respektive metod och MATLAB-kod som återfinnes i bilagorna.

This thesis describes the universalization, improvement and further development of acompact crane support frame for flatbed Trucks. The work has been conducted at Eloch Fordonsteknik AB (henceforth EFAB) in Uppsala.The aim of the work has been to shorten the assembly time of the product. By doingso, the product can be kept on shelf, which in turn results in shorter lead time. Thishas been done by universalizing the support frame to be compatible with most of thechassis EFAB works with. Additionally, the entire construction has been made lighter,which will make it a more attractive choice for customers.A pre-study was conducted and information was gathered internally, as well asexternally, in order to ascertain that no limitation or possibility was overlookedduring the course of the project.One such limitation has been the geometry of the Truck bed that the support frameshall be compatible with.

The degree project was made forZetterbergs Industri AB. The company is market leading in Europe in the heavyvehicle industry, designing and building body systems for Trucks.In their line of products is the hook lift called Livab, a flexible and uniqueproduct. The hook lift is often demanded by customers because its special ability tobe able to operate in situations with low roof clearance. The main operation principleof the hook lift can be described as a Truck stand, laid down.There are two main versions of the hook lift Livab, AL 26 and AL 32. These are ofdifferent load capacity, 17 and 25 metric tons of gross weight respectively.

Volvo Group Truck Operations i Umeå arbetar med arbetsmiljö och säkerhet på arbetsplatsen genom en så kallad säkerhetspyramid. Säkerhetspyramiden baseras bland annat på medarbetarnas rapportering av osäkert agerande och osäkert förhållande. Syftet med pyramiden är att identifiera risker och förhindra arbetsplatsolyckor. Baserat på rapporteringsstatistik och teoretiska antagandena i säkerhetspyramiden finns en anledning att tro att det förekommer en underrapportering. Syftet med studien var att undersöka om det fanns en underrapportering av osäkert agerande och osäkert förhållande bland kollektivanställda på presshallen och kaross.

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.

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a Truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Scania är en av världens ledande tillverkare av lastbilar och bussar för tunga transporter samt industri- och marinmotorer. Efter lansering av den nya lastbilsserien under 2004 som utnämndes till ?Truck of the year 2005? så tittar hyttutvecklingsgruppen framåt på nya projekt. Ett område inom hyttinredning som man vill fördjupa sig i är dörrpanelen. Med dörrpanel menas den del av inredningen som sitter på dörrens insida och normalt sett innehåller öppnings- och stängningshandtag, fönstervevar/elhissar, förvaringsfack etc.

Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania Truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by Truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).

The work that is the basis of this Master Thesis was performed on Scania´s group of cabdevelopment, and concerns the GPS-system in Scania´s Trucks. Today, the GPS-systemconsists of an active antenna mounted on the roof of the Truck. The antenna is connectedto the receiver with a coaxial cable.The purpose with this Master Thesis was to develop and evaluate a new GPS-system,where the information is distributed using a LIN-network. Today, each unit requiringGPS-information is equipped with its own antenna and receiver. This solution has beenthe most cost effective to this point.
