Abstract

A hauling device (10) for ski-lifts, equipped with a winding drum (15) for a rope (12), subjected to the recall action by a recall spring and with a centrifugal brake, comprises as the centrifugal brake at least a shoe (21) swingingly assembled on the drum (15), and intended for cooperating with the inside cylindrical surface (26) of a casing (11) which encloses the drum, the centrifugal brake, and the recall spring. The shoe (21) consists of a body moulded from plastic material, incorporating a metal mass (27), and is provided with a gasket (32) of self lubricating plastic material. The gasket (32) can be clutched on the body of shoe (21), and, in order to avoiding hydrodynamic lubrication effects in the presence of liquid inside the casing (11), the gasket (32) is positioned by engaging a tooth (35) protruding from the shoe (21) inside a groove formed between ribs (33) protruding from the gasket (32), its swinging being allowed around an axis parallel to the rotary axis of the shoe (21).
