Vimek AB är en, inom sitt segment, marknadsledande skogsmaskinsproducent belägen i Vindeln,Västerbotten. Deras produktion är uppdelad i två sektioner, en förmonteringsstation därstandarddelar kan monteras och lagerläggas, samt en slutmontering där alla delar monterassamman till en komplett maskin.Genom att flytta monteringsmoment från slutmonteringsgrupp till förmonteringsgrupp vill Vimekminska genomloppstiden för deras skotare 610 SE. Till Skotare 610 finns fem valbarakranspetsutrustningar där tiltgrip med bromslänk är den med god marginal främstförekommande.Projektets mål är att flytta tiltgrip med bromslänk från slutmontering till förmontering. Underlagtogs fram genom provmontage och intervjuer parallellt med en ständig dialog med montörer.Utifrån detta underlag beslutas att en förmonteringsstation med en fixtur om grund vara det somskulle passa in bäst hos Vimek. Monteringsfixturen konstrueras och monteras ihop på Vimek, ettnytt monteringsförfarande börjar ta form.Med hjälp av Vimeks montörer och sakkunnig personal inom kvalitét arbetades ett nytt konceptavseende montageinstruktion fram. Fokus på standardisering, förbättringsarbete och fortlöpandekvalitetskontroll har legat till grund för det nya konceptet.Projektet resulterade i en fungerande arbetsstation och en besparing av ledtiden med enbibehållen arbetsinsats. Nyckeln för detta projekt har varit ett gott samarbete med Vimekskunniga montörer och konstruktörer. / Vimek AB is a producer of forestry machinery located in Vindeln, Västerbotten. Their productionis divided in two sections, one preassembly group where standard components are beingassembled and put in stock, and one final assembly group who assembles all parts to a completemachine.By moving elements of assembly from the final assembly section to preassembly section Vimekwant to reduce the throughput time of the Vimek 610 SE forwarder. There is a selection of fivedifferent crane tip tools that comes with the Vimek 610 SE forwarder, where “tilt grapple withbrake linkage” is the most common choice by far.The goal for this project is to the move crane tip equipment “tilt grapple with brake linkage” fromfinal assembly section to preassembly section. A decision basis was formed through interviews,test mountings and a continual dialog with the assemble staff. The best way for Vimek to do thisis by designing a work station containing a mounting fixture. The fixture is constructed andassembled in Vimeks facilities. A new assembling procedure of the crane tip equipment starts totake shape.With the support of Vimeks assembling staff and competent personnel within quality a newconcept of assemble instructions is presented. Standardization, continual improvement andquality control has been the core of this new concept.This project resulted in a new work station for the preassembling section and a reducedthrougput time for the Vimek 610 SE forwarder. The key to this project has been a successfulcollaboration with Vimeks competent assemble staff and designers.

Volvo Hauler &amp; Loader Division in Arvika produces wheel loaders which they deliver throughout the world. The factory which is situated in Arvika is the largest wheel loader plant in the whole world, with its 1 100 employees. The different models stretch from L60E all the way up to the brand new L350F, with a loader capacity from six tons up to a staggering 35. The assembly of the different models are divided into three different assembly lines, Small (L60-L90), Medium (L110-L120) and Large (L150-L220). 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. One scenario, where the work-station resembles the current workstation, but with a improved layout and safer working environment. The second scenario states a working-station where fully pre-mounted boom units should be produced, although this station requires some alterations in the construction which are mentioned in the paper. The last scenario is a vision of the future, where all three lines are gathered into one big line, accordingly with the visions of the company outline.
