BTI MBS Rockbreaker System mounted on Portable CrusherDrawing = BTI MBS Rockbreaker System
 

BTI's MBS Series of Portable Rockbreakers offer an on-plant, road to operations, permanent solution to portable and mobile crushing applications where safety & productivity are essential.

  • Low Profile
  • Dependable Boom Design
  • Narrow Mounting Requirements
  • Rugged Boxed Sections

Features & Benefits:

  • High strength steel (bent, 4-plate) construction 65 ksi tensile strength; 50 ksi yield strength for longer service life
  • Reinforced pivot and mounting pin joints from improved durability
  • Hardened steel bushings in pivot joints and larger diameter pivot pins provide reduced bearing pressure and increased service life
  • Enclosed oil bath bearing system with suspended drive motor for increased useful life and improved serviceability
  • Increased cross sectional strength of boom and dipper where high stress is realized
  • All hose design allows for improved routing and ease of replacement
  • Valve bank positioned for improved access based on specific plant design
