Patent ID: 7662058

Claim:
Bull-wheel for a rope transport installation, comprising: a hub of circular cross-section for passage of a shaft, a peripheral rim with an annular groove for housing the rope, the rim being joined to a support enclosure by a metal connecting framework comprised of a perforated central disk extending between the rim and the support enclosure strengthened by radial rigidifying arms, and fixing members to assemble different elemental parts of the framework and of the rim to one another, wherein: the rim is radially subdivided into several arced segments assembled to one another by first fixing members passing through radial flanges of the arced segments, the hub is fixedly secured to the support enclosure, the support enclosure comprises at least one plate provided with at least one polygonal surface and a periphery defining a plurality of bearing surfaces, the bearing surfaces confine the polygonal surface and are perpendicular to the polygonal surface, the perforated central disk and the radial rigidifying arms are assembled on the bearing surfaces by second fixing members, and the bull-wheel distributes radial forces uniformly regardless of the angular position of the bull-wheel with respect to the rope.
