Suspension for silo unloaders

摘要

A top silo unloader is of the type which has a cutter-conveyor pickup arm, an impeller, a drive ring above the cutter-conveyor pickup arm, and support arms in a horizontal plane above the drive ring to which suspension cables are connected for moving the unloader vertically in the silo. Improved support arms have downwardly and outwardly extending offset portions outside the drive ring which have their free ends in a plane above the bottom of the cutter-conveyor pickup arm, and means on the free ends of the offset portions to receive the suspension cables.
