J Hvidtved Larsen was founded in 1915 by blacksmith Jacob Hvidtved Larsen, who made a living repairing motorcycles and other mechanical devices as well as being the local driving teacher. Today, the company focuses exclusively on sewer cleaning technology and has an export share of 70-80%. JHL now has exports to 28 countries and sales partners in Russia, Latvia, Poland, the Netherlands/Belgium, the UK, Ireland, Australia/New Zealand, Sweden, and Norway. Before its investment in new production design, the company scraped by – with small and varying profit margins. Today, JHL has sound and rising profits – currently at DKK 17 million – and a stable workforce of 130.

RATIONAL PRODUCTION

Ten years ago, J Hvidtved Larsen was a small machine shop

This assignment went to Nils Toft from the design firm CBD,

like so many others. They produced sewer cleaning technology,

and as he would soon discover, he had his work cut out for him:

outside one’s main area. So, sometimes we were really off the mark, and that affected our earning capacity.”

This idea was well received by JHL, and the new production design, which is based on standard modules – but still with

the down same old path was no longer satisfactory – it was time to expand the company. The R&D manager describes the early stages of this endeavour: “We analysed our production and found that the most prominent product – and a product where we had gradually become market leaders in Denmark – was sewer cleaning vehicles. In Denmark, the total demand for these vehicles does not exceed 20 or 30 a year, so if we wanted to expand within this industry, we could only do it through exports.” The managing director therefore began to join business delegations on international tours, and the very first stop, St Petersburg, proved to have a big demand for sewer cleaning technology. So big, in fact, that there are now 80 sewer cleaning vehicles carrying the JHL logo in operation in St Petersburg alone. Until then, however, JHL had only produced some 20 sewer cleaning vehicles a year, so they now had to work out how to turn out enough vehicles to cover the demand. In other words, they needed to take a long, hard look at their production design.


SATISFIED CUSTOMERS

Three pieces of advice from Jesper Hejselbæk

“Now we’re telling the customer what he wants, unlike before, when the customer defined the assignment,” says Jesper

able to pace the work much more evenly, we can maintain a much more stable workforce, compared with the past, when the workforce would cycle up and down based on the order books.” One might expect the customers to be unhappy with the standardisation, but that is not the case – Jesper Hejselbæk explains: “One of CBD’s designs was a standard operation panel, which means that the buttons controlling the various functions are in the same location across different vehicles. That is a huge benefit for the operators; it increases their flexibility that all their drivers can operate all the different vehicles. It is also an advantage when the vehicles come in for service that the wiring is arranged in the same way, as opposed to the past when we had handmade drawings for the individual vehicle.” Thus, the new production design has many advantages, which now seem obvious to anyone. But according to Nils Toft from CBD, it is not unusual that it takes a design firm to sort things out: “We work with a wide range of companies, and inefficient production processes, like the ones we found at Hvidtved Larsen, are very common. First of all, with our experience, we notice these things immediately. And secondly, it often takes an outsider to adopt a sort of helicopter view and disregard the way things have been done traditionally.”


OUTSIDE INSPIRATION

The success of the FlexLine series in 2000 gave the staff at JHL a taste for more, and since then they have continued to involve external design assistance. In 2002, this resulted in the RECycler model, which was developed in collaboration with the largest buyer of sewer cleaning vehicles in Denmark, ISS. The idea is simply that RECycler cleans the waste water and recycles it for jetting rather than using fresh, clean water from the tap. This technique reduces water consumption, which means improved resource efficiency and environmental sustainability, but that is not even the most important advantage for the customer. ISS has calculated how much effective jetting time they get with the RECycler versus traditional sewer cleaning technology. And this is where the biggest benefit is found: With a traditional sewer cleaning vehicle, 80% of the time is spent driving and filling up the water tank, while only 20% is effective operation time. With the RECycler, these factors are reversed: Only 20% of the time is spent driving and filling up the water tank, while an impressive 80% is spent on the job.

throughout the world, as JHL now has exports to 28 countries. With CityFlex, the design task revolved mainly around new materials. A small sewer cleaning device has to go on a small lorry with a maximum load of 7.5 tons. Since the vehicle itself weighs in at 2.5 tons, and it must be able to carry some 3 tons of sludge, that leaves only 2 tons for the equipment that weighs 8-10 tons in a normal sewer cleaning device.

“Of course, you can’t put everything down to design. But working with designers has clearly helped drive our company forward,” says Jesper Hejselbæk, who encourages other companies to take on design. In his understated way, he says, “No harm in having a meeting.”

“If you get three engineers together, they’ll all say the same. But if you get an engineer, a designer, and maybe a PR guy together, you’ll get a variety of ideas, and that’s when things begin to happen.”
