<p>A rocker arm assembly supporting the rope of an aerial tramway installation, comprises sheaves, the spindles of which are so fitted as to enable their easy disassembly. The spindles are cantilevered from an arm fitted on the inward facing side of the sheaves. The arm, preferably made of mounded material, preferably has a rope catcher shoe which protrudes on the outward facing side of the sheaves. A detector of excessive rocker arm swing, due to the rope falling on the catcher shoe or to a sheave being lost, is preferably incorporated in the boss of the arm and protrudes into a shearing groove in the articulation spindle of the arm.</p> |
