MasterRoc ABR 5 – Liquid anti-abrasion agent for Hard Rock and EPB Tunnel Boring Machines (TBM)

How does MasterRoc ABR 5 work?

MasterRoc ABR 5 is specifically designed to reduce abrasion and dust for tunnel boring machines operating in hard rock mode.  It is used to reduce abrasive wear to the cutting tools, and to substantially reduce dust formation during excavation as well as cutterhead clogging.

What are the unique features of MasterRoc ABR 5?

MasterRoc ABR 5 reduces abrasive wear for cutting tools. Better cooling of the cutterhead, improves the rubber seal durability, and extends the life of the cutter bearing.

What are the benefits of MasterRoc ABR 5?

  • Effective reduction of dust formation, leading to considerably improved working environment for TBM personnel
  • Reduce TBM down time due to less frequent cutter changes, therefore more time available for excavation
  • Improved transfer of the muck from the cutter head, resulting in reduced risk of blockage, cleaner cutter discs and cutterhead area, which make maintenance easier and reduce cutter disc changing time
  • Overall cost saving due to higher monthly advance rate and lower maintenance cost
