History - The present day of the loader excavator
Daniel Åkerström is one of the engineers behind developing Huddig's loader excavators. He joined Huddig in 2000 and has since been involved in developing many machine models, including the latest HUDDIG 1370 and the full hybrid loader excavator HUDDIG TIGON.
Today, Daniel and the team are working to develop Huddig's model range further. The focus is constantly on improving the machines' performance and operating economy and refining what makes the HUDDIG machines unique - the operator's driving experience and comfort.
"My 23 years at Huddig have been a fascinating journey. I have to pinch myself sometimes when I think about the many models I have been involved in, not least the world's first full hybrid loader excavator. A lot has happened during my years at Huddig, and our development together is fantastic. I am proud of where we stand today, with TIGON and our latest model, HUDDIG 1370."
Already in 2012, Huddig's journey towards the future began. The goal was to be at the forefront of the green transition in the construction industry and contribute to reduced emissions.
"HUDDIG machines are often used to build infrastructure such as power lines, fiber networks, and utility projects. Therefore, we chose to develop a full hybrid machine that could also be used to develop the charging infrastructure central to the upcoming transition."
When the first pre-series model of HUDDIG TIGON was shown at the Swedish Machine Fair in 2015, it attracted much attention. The TIGON continued to be developed through pilot tests, and the company worked constantly to improve the solutions concerning the prevailing conditions. Six years later, the first customer machine was delivered.
"We have always had very close contact with our customers. We see it as a matter of course to listen to our customers and invite them to our factory. It is for them and their businesses that we develop our machines. By having direct contact between designers and machine operators, we always keep our ear to the market."
During the development of TIGON, a more powerful excavator unit was developed in parallel with the successor of the HUDDIG 1260 model. The new HUDDIG 137O model was designed to be even more competitive in the market, including a higher lifting height and increased slewing torque.
"In early 2022, we launched the HUDDIG 1370, and customer feedback was very positive. With HUDDIG 1370, you lift both higher and faster. The digging geometry is a completely different experience compared to the previous model - thanks to the more powerful and longer excavator unit."
Starting with the HUDDIG 1370, Huddig also wanted to offer customers two different powertrains for each model: hybrid or hydrostatic. With this, Huddig entered a new era in how to deliver machines.
"The market needed more options in the transition to fossil-free construction machines. Some customers immediately take the step to hybrid operation, while others still feel more comfortable with machines with traditional operation. Technological development continues to advance in line with the new environmental requirements, with diesel engines, for example, improving significantly with the introduction of the Stage 5 requirement."
Independent tests gave impressive results.
Ecoloop is an independent Swedish organization working to drive tomorrow's circular resource management. During 14 weeks in 2022, Ecoloop tested Huddig's hybrid machine, HUDDIG 1260T, in real-life conditions to map how much lower fuel consumption and how much less emissions the machine produces compared to traditional construction machines.
"Ecoloop's tests demonstrate the significant fuel savings possible with a hybrid machine. The HUDDIG 1260T machine tested had a 33 kWh battery, but all of the new machine models (HUDDIG 1370T) come with a 44 kWh battery for even better efficiency. The new, more powerful battery and, for example, being able to charge the battery during the night for maximum capacity provides an additional benefit. Optimizing the charging interval and driving style means that the actual driving time on electricity is longer, leading to further fuel savings," Daniel says.
Huddig's vision for the future is to be a leader in construction machinery in ten years, especially regarding green alternatives.
"I think the transition will go faster than we think, and we are now at the beginning of the green revolution. In our continuous improvement efforts, the goal is always to increase productivity, efficiency, profitability, and customer satisfaction. I look forward to continuing the development of technologies that contribute to the evolution of customers and society," Daniel concludes.
