Development of 300kg HD LightLift for Chandeliers and similar heavy attachments (English)
Abstract [en]

The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.

This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.

This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.

The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.

In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.

Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance.

 

Abstract [sv]

LightLift Esystems AB tillverkar patenterade, motoriserade lyftsystem för belysningsarmaturer till utrymmen med höga takhöjder. Företaget vill utveckla en ny konstruktion för enstaka punktbelysningar för att utöka sin konkurrensförmåga.

Föreliggande projekt innefattar utveckling av en ny konstruktion utgående från en av företaget given specifikation. Den nya konstruktionen skall kunna hantera laster upp till 300 kg och dimensionerna skall hållas så små som möjligt med bibehållande av den ursprungliga lyftenheten.

Detta dokument innehåller alla utvecklingssteg som följts fram till slutlig lösning, likaså materialval, val av tillverkningsmetod och monteringssätt för samtliga komponenter.

Den valda lösningen visar sig vara konkurrenskraftig i jämförelse med alternativen emedan den kan lyfta tredubbla lasten med bevarade yttre dimensioner.

Av konkurrensskäl är självklart också formgivningen av betydelse för uppdragsgivaren, varför även hänsyn till detta togs. Från estetisk synpunkt visar sig den valda lösningen vara fördelaktig emedan den lika lätt kan döljas bakom ett "falskt" innertak som kapslas in i en lämpligt utformad kåpa av plast.

Lösningen uppfyller således alla de ställda kraven i specifikationen. Den är tillförlitlig, kompakt, billig att tillverka, lätt att montera och har en tilltalande formgivning.
