A crawler drill is a device that quarries stones or ore. Our chain is used for lifting and lowering the chain drill unit.

Advantage

• ・Application challenges
  Sand and mud adhere to the chain. Large shock impact from hard rocks.
• ・User assessment
  Tsubaki was highly evaluated as it distinctly outperforms other brands. The roller durability that withstands shock and fitting pressure output against lateral loads contributed to this positive feedback.
