• What is the difference from just using a conventional mini excavator in the kiln?

  As the Brokk is remote controlled, the job can be started earlier with Brokk as the operator can be outside when the coating is being demolished at the outlet. Furthermore does the three-part arm system allow for much faster repositioning of the arm and no damage to the shell. The hitting power is much greater on a Brokk machine and the coating or bricks will simply be demolished much faster. The Brokk machines are built to work in hot and dusty environment and will not stop when you need it the most.

  Yes, the Brokk machines can be used in the coolers, crushers and even in the cyclones to break coating and refractory

• How can the Brokk machine be brought into the kiln?

  The Brokk machines are very compact when folded together this makes it possible to enter even the most narrow openings in the hood and pass any duct. Thanks to the low weight on the Brokk machines, they can enter the kiln over a bridge from the burner platform to the kiln outlet

• Will the shell be damaged by the Brokk machines?

  No, thanks to the three-part arm system the Brokk machines are able to follow the shell unlike conventional excavators. This allows for an efficient and safe way to debrick the kiln without damage to the shell.

• Is it safe to use power cable in the process industry?

  Yes, with an earth fault relay on the site, it is perfectly safe to use electric powered machines in the factory.

• Why not use a conventional excavator for removal of slag and refractory?

  The Brokk machines offers much more hitting power than conventional excavators and the boom design allows for faster debricking and longer reach. The Brokk machines are remote controlled which puts the operator in the best position to see the tool and prevent any damage to the furnace or ladle for instance.

• Is it possible to demolish only one lining of refractory and keep the safety lining?

  Yes, thanks to the three-part arm system and the adjustable blow frequency the Brokk machines can demolish refractory in a very controlled way.

• Can one machine be used for several applications?

  Yes, the Brokk machines are very flexible as they can be easily transported within the plant. A Brokk machine will always be busy with something unlike dedicated systems.

• Can the Brokk machines work in hot environments?

  Yes, the Brokk machines can be equipped with several options to work in high ambient temperature and even red hot areas for the arm system. Please check out the options page for more information

• Can Brokk machines be used for several applications?

  Yes, the Brokk machines are multipurpose machines and can be equipped with breakers, scabblers, buckets, drill rigs and many other tools. This means you can replace several machines with only one Brokk and save on the set-up time.

• Brokk machines look small compared to conventional excavators for tunneling?

  Brokk machines are available in many sizes but what they all have in common is that they are much more productive than conventional machines and can carry heavy tools. The smaller size makes sure the tunnels are not blocked for other traffic or construction vehicles.

• Why not just use conventional excavators for demolition?

  Brokk machines are designed for demolition with heavy hydraulic attachments. The productivity is much higher and according to customers up to 5 times more powerful than same size excavators. The remote control puts the operator in a position to do controlled demolition and cut rebars for instance. Brokk machines are electric driven and which open up possibilities to work inside buildings with no fumes. If equipped with concrete crushers you can do silent demolition 24/7 without disturbance to the surrounding and speed up the project. The low weight makes it possible to work on upper floors with less, or no need for propping.

• Why not just use concrete cutting equipment to remove concrete inside the buildings?

  Brokk machines are a complement to cutting and coring which can be costly and time consuming because of the consumables and set up time.
