Introduction Of Internal Combustion Rail Bolt Spanner Wrench Railway Track Wrench
The NLB-300 gas power/electric Railway Impact Wrench is designed for loosening and tightening rail tie bolts and nuts on railway tracks, meeting the locking torque requirements for rail fastenings. Equipped with a rotating four-wheel travel mechanism on its base, it can move along the rails.
The NLB-600 gas power Railway Impact Wrench and NLB-600 Dual-Head Internal Combustion Bolt Wrench feature dual sockets for simultaneous operation. They convert impact torque to static torque, minimizing pressure deviation in processed rail fasteners. These tools offer flexible directional switching and straightforward operation.
The (NB)NLB-500 and handle Railway Impact Wrench feature compact size, light weight, high maneuverability, and dual-stage vibration damping in the handle for easy portability. They are particularly suitable for regional track maintenance operations in ballast areas. As one of the lighter impact wrenches, they deliver substantial torque with excellent balance and can stand upright.
