摘要: Improved telescoping railcar uncoupling levers have improved bearings that resist damage. Moreover, the uncoupling levers include removable lock lifter linkage hooks. In addition, the uncoupling levers comprise an improved handle loop shape allowing the levers to be more easily installed and/or removed when damaged. Methods of using the same are further provided.
