ABSTRACT:
A conveyor is powered by a rotating, generally horizontal drive tube or shaft engaged by angularly disposed trolley wheels, in which trolleys support the conveyed products or materials above the drive tube and clear of any parts of the conveyor structure that would interfere with the desired path of travel. Each of the trolleys is provided with load wheels which ride on load rails above the drive tube and associated drive wheels, thereby providing a structure upon which a platform or other support may be mounted for bearing the transported products.
