ABSTRACT:
A safety device for cable sheave installations, which provides cable guide assemblies which block hands and the like from being drawn in to be injured between moving cables and sheave wheels. The cable guide assemblies are pivotally attached to the outside ends of arms in turn pivoted at their inside ends from the sheave wheel support structure. The cable guides also prevent injury and property damage from cable jump, by guiding cables with large approaching fleet angles directly onto the wheels.
