ABSTRACT OF THE DISCLOSURE A rocker arm assembly for support of the haul rope of an aerial tramway or the like is disclosed. The assembly includes rocker arms, rope supporting sheaves rotatably mounted to the rocker arms and cantilevered from an inwardly facing side of the rocker arms. The rocker arms are additionally formed with rope catching groove or recess positioned outwardly of the sheaves and having a configuration which will enable not only the rope, but a hanger arm and grip to pass over the rope catcher in the event that the haul rope derails from the sheaves. The rocker arm assembly also preferably includes a platform which acts as a mount for the rocker arms and can be used for maintenance and repair of the rocker arms and rope supporting sheaves. Additionally, the rocker arm assembly includes haul rope derailment responsive apparatus formed to shutdown the tramway operation upon derailment of the rope from the sheaves.
