Modular Solutions that Scale with you

Readily from CAD to Production in minutes

The PORTABOT is KRANENDONK’s smallest and most flexible robotic welding solution. Ideal for non-repetitive, hard-to-reach structures, it combines lightweight mobility with automated precision. Equipped with magnetic, crawler, or track bases, and powered by RinasWeld software, it enables fast, high-quality welding anywhere, without programming or teaching.

All you need to know

Engineered for practical use on the shop floor, the PORTABOT brings robotic welding within everyone’s reach. Every aspect of its design, from its lightweight build and easy deployment to its stable performance, is focused on making automation straightforward and effective. From quick setup to consistent results, it turns complex, non-repetitive welding tasks into a simple, reliable process that fits seamlessly into your production environment.

Lightweight and easy to deploy

Weighing only 11.2 kg (24.7 lbs), it’s easy to carry and set up anywhere. The compact cobot design allows quick repositioning between work areas or structures, without the need for cranes or fixed installations. Magnetic or track-based mounting ensures stable placement on any steel surface, enabling fast deployment wherever welding is needed.

Ideal for small or complex structures

The PORTABOT brings robotic welding where traditional gantries can’t go. Suitable for all types of steel structures, it delivers precise, consistent welds, even in confined or hard-to-reach spaces. Instead of moving the workpiece, you simply bring the PORTABOT to it.

Operate multiple cobots simultaneously

Manage several PORTABOTs from a single tablet for maximum productivity. The system allows one operator to control multiple cobots working in parallel, each executing its own automated welding program. This multi-cobot approach increases throughput, ensures uniform weld quality across all stations, and delivers flexible scalability for any production setup.

From 3D Model to Automated Weld in Minutes

The PORTABOT workflow is designed for maximum simplicity. From uploading your 3D CAD model to executing the weld, every step is streamlined to minimize manual effort and maximize productivity. In just a few straightforward steps, you’ll move from digital design to a finished weld, no programming, no teaching.

  1. Import your 3D CAD model.
  2. The software automatically detects welds and generates the program.
  3. Position the PORTABOT on the workpiece using the magnet base.
  4. Select the job on the tablet.
  5. Mount the cobot on the base.
  6. Start welding. That’s it.
  7. Repeat the process for the next cobots.
