Nyutveckling av sjunkspärr
We got in contact with Marco AB, who we?ve had contact with before concerning earlier projects, to find out if they were interested in arranging a larger project for our last class (Examensarbete 15hp). They were very positive to this proposition, and soon they offered us a project regarding reconstruction of their current mechanical device that absorbs all the force from the lift itself when it is at a predefined level (sv. sjunkspärr). The current solution does fulfill the requirements that are given, however it is not a solution that gives a high level of satisfactory. It is complicated, both to manufacture and assemble, it is not recyclable due to the hydraulic system and in addition it has retardation issues. But most of all, it is expensive. That may raise the question; how come Marco is still using the current solution? The device is an accessory for the lift tables that Marco produces and sells, not a standard solution. They produce about 100-150 of them every year, and therefore is a small part of their total income. This in addition to the solution being bought from a consultant, they merely tested the product and then added it to the assortment. The project ended up in a solution none of us could have foreseen, neither by function nor visualization.
