Brokk 520D

The mean, green demolition machine. For the most environmental-friendly diesel demolition on the planet.


The Brokk 520D is a beast. With 40 percent more hitting power and the ability to size up attachments, this diesel-powered machine outperforms everything its size. It’s stronger, faster and has a longer reach — while keeping key compact dimensions of its predecessor, the Brokk 400D. Adding the Brokk SmartConcept — the reliability of SmartPower™, the clever features of SmartDesign™, the ergonomics and productivity of SmartRemote™ — this machine is optimal for the heaviest of tasks in any industry. Meeting new emission standards (EPA Tier 4 Final/EU Stage IV) it is also the greenest diesel demolition robot on the planet.

  • 40 percent more demolition power with the BHB 705
  • Meets the toughest emission standards
  • Rugged and reliable Brokk SmartPowerTM
  • Brokk SmartDesignTM and SmartRemoteTM
  • Compatible with all Brokk 400 and Brokk 500 attachments

Brokk breakers are made for maximizing your efficiency. There are breakers for each model, optimizing the power of your specific Brokk machine. It hits harder and faster then other breakers on the market, still with less noise and vibrations.

Concrete crushers

Our crushers are just as scaringly effective as they look. Provides free rotation and has exchangeable tips. The larger crushers also has additional teeth and pulverizing pads.

Metal Shears

The sane and easy way to cut pipes, bars, girders, profiles, structures, etc. Different jaw sets, and replaceable cutting and breaking tips available for some models. Rotator with continuous rotation.


With a bucket on your machine, your Brokk transforms to world’s most agile excavator, perfect for digging, loading, sorting & separation of material and debris.

Clamshell buckets

A variety of clamshell buckets transforms the Brokk to the perfect machine for loading, sorting & separation and transporting material and debris.

Multi Purpose Grapples

Brokk offers a broad range of demolition grapples that help you do the job more effectively. Perfect attachment for loading, sorting and separating debris (rock, concrete, wood, metal work). Rotator allows for continuous rotation.
