Martin LuinstraMartin Luinstra: “We’ve made tippers out of steel for years. And I always thought: why does that to be so heavy? You can transport so much more if the tipper bin is lighter. So, yeah, then you start thinking up out of the box alternatives. Paper, cardboard. Impossible, of course. Carbon? Too expensive. Plastic? Why not. We started studying the question and ended up with composites. They use it in the automobile and aircraft industry too. It’s light, strong and durable. Before we made a prototype, we did market research. 80% of the transport companies considered a light composite bin a great idea, but 99% indicated they had no faith in the idea. Jokes were made about it. Lunchbox, Tupperware bin. Once we presented the first prototype in 2010, the mood changed completely. In the future, we expect to sell a thousand each year. And it doesn’t stop at the tipper. We’re also busy with composite tanks and containers. This is the start of something beautiful.”

History: on December 10, 2010 a group of companies in Overijssel had a world’s first with a new transportation product. It involves a lightweight composite tippable loading bin and it’s a unique invention from Roelofs Kipper. The new unique tippable loading bin is 50% lighter, stronger and more energy-efficient and quieter than the current metal bin. Various transport companies are already interested in the invention. Volvo Trucks and GS Meppel, among others, are going to market this new tipper if we successfully complete the project that is currently underway. In addition, there is interest from both Germany and Belgium.

The new composite loading bin can largely replace the current metal skips in the future. An advantage of the durable, lighter and stronger tipper is that two extra tons of load can be transported. In addition, the tipper, thanks to its composite material, can withstand high temperatures of around 180ºC and uses far less fuel during empty transport than vehicles with the existing metal type. The developed tipper is a very large type - 6½ m in length, 2½ m wide and around 2 m high, meant for placement on a truck chassis. A second version for a 9 m long trailer is also ready. The loading trailer will be deployed for the transport of dumpable products, such as gravel, sludge, sand, broken fill, animal fodder, agricultural crops, industrial waste and (warm) asphalt.
The tipper is built up from layers of various (insulating) composites. Composites are plastics reinforced with fibers that are up to six times stronger than existing metal materials. With clever construction, considerable reduction in weight can be achieved with this material. This was also one of the project objectives that preceded the current initiative. Composites are often called “the material of the future.” In this production technique, the connection technique between the various materials was essential so that all production requirements were satisfied. The partnership has also developed and improved tipping technique. With this development, the focus was shifted to a new scissor cylinder which places the tipper’s point of gravity farther forward. This gives rise to an optimum axle – load distribution. The stretch strips (sensors) present and integrated in the tippable load bin ensure that the degree of loading, axle pressure and temperature can be measured from the cab.
Composite’s advantages are its considerably lower weight, insulating property and noise reduction when loading and unloading. With an empty bin, the user saves a lot of fuel and when the bin is full, the rule applies: the lighter the bin, the greater the size of the load. And it has turned out that even the temperature of the asphalt can be reduced thanks to the insulation, since it cools off less quickly underway. The sale price of the composite tipper is 1½ times that of the metal tipper; the payback period is 1½ years and at the end of its economic life – lasting seven years – the user will have achieved a cost saving of roughly € 109.000. In this figure, the fuel saving of nearly 10% has not even been included.
