The NLB-1900 is a highly regarded portable rail bolt wrench, relying on a robust internal combustion engine to deliver high-impact torque for efficient track bolting operations. This equipment is a staple for track workers, especially in remote areas where reliable access to external power is limited. The NLB-1900 is engineered to provide the consistent, high-performance fastening required to ensure the structural integrity of jointed rail tracks. The machines design prioritizes durability and high impact efficiency for fast work cycles, while its overall structure is optimized for handling and portability, minimizing operator fatigue during strenuous, repetitive tasks like tightening and loosening rail bolts across a large maintenance section.
