Our Bantam Block combines fewer pounds with a tough attitude.

Columbia Steel's Bantam dragline dump block for reduced rigging weight

A simplified bearing arrangement allows for more efficient and more accurate rebuilds, while the bearing cavity itself is protected by improved material exclusion due to the enclosed design. Bearing assembly features and benefits include:

  • Reduced weight
  • Sheave rope groove geometry complies with wire rope industry guidelines
  • Increased dump rope life when upper rigging is switched from two 48″ blocks to one 60″ block
  • Accepts ferrules without disassembly
  • Available for most pin and rope sizes
  • Uses a mechanically sealed bearing assembly
  • Same-plane and opposite-plane designs for all Columbia dump blocks are available
