Why modified machines matter more than ever.

The problem with finding non-standard machines

If you're in construction, infrastructure or mining, chances are you've run into a job that your standard fleet just couldn’t handle. Whether it's working in a narrow tunnel or clearing heavy snow in mountainous terrain, the need for machines that can do more than the average excavator is very real.


Yet, when that need arises, where do people turn? Google? A few calls to equipment rental firms they already know? Most people discover the same problem: finding the right modified or specialised machine is incredibly difficult. The internet isn’t built to help you find what you really need. Most of these machines don’t even appear in search results. It’s frustrating. It's slow. And it often ends with compromise.

Why special solution providers remain hidden despite their innovation

Special Solution providers, also called machine modifiers, are the companies who build these tailored solutions. They take a base machine and turn it into something extraordinary: a rail-excavator, a high-reach demolition or a tunnelling machine.

These companies are often brilliant engineers, able to modify to high standard. But they are not marketers. Many of them don't have proper websites. Some don’t show up in Google. Others operate entirely on word of mouth. The result? Their innovations stay hidden. Potential customers don’t know they exist.

This lack of visibility doesn't just hurt the providers. It slows down progress for the companies that rely on specialised equipment to get complex jobs done. When buyers can’t find the right tool, they either make do with the wrong one, delay the project, or overspend.

Examples of niche use cases

Let’s say you’re a procurement manager at a large civil engineering firm:


  • You need a snow-capable excavator for a winter rail upgrade in northern Europe.
  • You’re looking for a long-reach boom setup to safely clear material near a water infrastructure.
  • Or you're trying to find a tunnelling machine that’s compact but strong enough for urban underground works.


All of these machines exist. But only if you know where to look. Right now, there is no simple way to browse providers of these modified machines globally...

The opportunity to connect the two worlds

Justr was created to solve this exact problem. Our platform connects the innovators, the special solution providers, with the professionals who need their expertise. Think of it as a digital showroom for machines you can’t find anywhere else.
