Ein derartiges Siebtrommelgerippe lässt sich in eine Vielzahl von Bauteilen mit geringem Transportvolumen zerlegen und ist somit für einen Transport, insbesondere einen Straßentransport oder einen Containertransport auf dem Land-, See- oder Luftweg optimal geeignet. Die Außenringe bilden flache Scheiben, welche ggf. hochkant und stehend transportiert werden können. Die Längsrippen bilden lange Stäbe, welche in Fahrtrichtung liegend transportiert werden können und die Querrippen bilden kurze Bogenabschnitte, welche ebenfalls in Fahrtrichtung liegend transportiert werden können.The screen drum frame according to the invention comprises a left outer ring, a right outer ring, a plurality of longitudinal ribs and a plurality of transverse ribs, wherein the longitudinal ribs extend continuously from the left outer ring to the right outer ring, wherein the longitudinal ribs are formed as U-profiles, wherein the longitudinal ribs with the Outer rings are connected by connecting means and wherein each transverse rib connects at its two ends in each case two adjacent longitudinal ribs and is connected thereto by connecting means. Such a screen drum can be broken down into a plurality of components with low transport volume and is thus optimally suited for transport, in particular road transport or container transport by land, sea or air. The outer rings form flat slices, which can be transported upright and standing if necessary. The longitudinal ribs form long rods, which can be transported lying in the direction of travel and the transverse ribs form short arc sections, which can also be transported lying in the direction of travel.
