Patent number: 4243352Abstract: A silo unloader is of the type having a tripod with inwardly and upwardly inclined legs, including a main leg and lateral legs, surmounting the wall of a cylindrical silo, and a silo unloader mechanism has three generally radially extending horizontal support arms to each of which is secured a suspension cable trained over a sheave at the upper end of one of the tripod legs to suspend the mechanism in the silo. Each of the sheaves is journalled in a yoke which is freely suspended at the upper end of a tripod leg, and because of the way the suspension cables must run from the winch to the sheaves, the yokes are displaced from a vertical suspension by the load on the cables. The structure of the support arms permits securement thereto of the three suspension cables at points which compensate for the displacement of the sheave yokes, so as to cause each cable to hang effectively vertically from the sheave over which it is trained.Type: GrantFiled: May 10, 1979Date of Patent: January 6, 1981Assignee: Chromalloy American CorporationInventors: Cary L.
