Cab design for a 60-ton slag hauler
During the spring, Felicia Aneer & Carl Hansol from Industrial Design Engineering developed a new cabin concept for 60-ton slag hauler at NMV.
The project is based on a feasibility study in the autumn of 2015, in which six students (including Carl) developed an exterior concept for a slag hauler. Felicia and Carl has now further developed the concept, and also designed the retail and interior design. The work is extensive and they have made a feasibility study where they interviewed stakeholders at SSAB in Luleå, Boliden and Finland.
They also made a number of visits to study how similar machines are designed, they have, for example, studied loaders and tractors. Felicia says that "the feasibility study has been crucial, in terms of gathering as much information to make a product that is relevant to the user, especially when it is in an area that you have no knowledge off " Carl points out that many of design decisions are based on arguments which they have received during the pilot study.
Felicia says that the biggest challenge in the project was that: "from the beginning we now very little about the area, I did not even know what a waste truck was. It has probably also been the most enjoyable - it is possible to get as far from not knowing anything, if using a structured process.".
Another challenge is to understand the rules, standards, laws and regulations affecting the vehicle, a slag truck located between several directives so it is a challenge to sort out and understand such as the working environment directives that are important, here, we have received much support from the NMV .
During the feasibility study, the students have adapted and developed their own methods. Carl says: "we have adapted the methods to the situation, and then they have become so off from the original method that we have chosen to rename them". Felicia continued, "when we start using the methods we notice that they have a life of their own and evolve, they are adapted to the situation, then we try to retell it"
Reflections from clients
Kenth Mukka, construction manager at the NMV "The result is above expectations, it will be a product, and in 2017 so customers will get a cabin with this appearance."
Kenth tells us that the great advantage of working with the University is: "to get someone who has not been involved in the production earlier, thay may see a problem with brand new eyes, do not have any preconceived ideas, not locked up in technical solutions and can think freely - it has really payed off! "
Hannes Wikström at the NMV has been the industrial supervisor: "its nice that when students arrive, they have read so much design, knowledgable of software, at the same time, we at MNV have a high technical level at what we do so we do not put as much emphasis to communicate and teach students, so we can put a focus on what the students are good at"
In the project the students developed a full-scale prototype in the workshop, Hannes stresses that:"I think it's so good to do it, you learn so much about why things look the way it does, it normally depends on how it is manufactured. They get an understanding of how to design for manufacturing. "
About the final result Hannes says: "It's great, we have reached much further than I thought, we had an ambitious goal, but they also had time for the small details, decals and prints - do la ittle extra on everything "
Felicia tells about the experience to build the prototype: "To design something in the morning and then come down to the shop and have the physicl object it your hand in the afternoon has been a nice experience, also to experience all manufacturing methods available on NMV"
During the project, they have used laser cutting, bending, welding, etching, riveting, bonding, they have also been using 3D-scanning and 3D-printing. In the project, they have also been responsible for communicating with suppliers to obtain the appropriate displays, controls, and chairs and other furnishings, Felicia says: "A lot of time was spent locating suppliers of components like the seat, steering wheel, hand controls etc" Carl says "it's impossible not to take the first supplier either, we've scanned the market and we needed to take design decision on features we really want, and reflect on the design of components even though you have not designed them"
