ABSTRACT:
A haul rope grip assembly for an aerial tramway is disclosed which is suitable for both detachable and permanent gripping of the tramway haul rope. The assembly includes a gripping head having a pair of relatively spaced apart converging haul rope gripping surfaces oriented for gravity biasing of the surfaces into wedging engagement with the haul rope under loading of the grip. Additionally, the assembly includes a jaw positioned proximate the surfaces and formed to apply supplemental force to the haul rope in a direction tending to further wedge the haul rope between the gripping surfaces. The jaws are also formed to unwedge the haul rope upon movement from a closed to an open position. In the detachable grip assembly, a pair of independently movable jaws pivotally mounted and actuated by levers are biased closed with leaf springs that are spaced apart to allow for a hold down sheave. In the permanent grip assembly, the wedging surfaces are further oriented to increase wedging as the grip passes around a horizontal bull wheel. The method of securing a grip assembly to an aerial tramway haul rope is also disclosed.
