1. A scraper system for a conveyor belt, having
a system carrier,
at least one scraper module, attached to the system carrier, having a scraper element for abutting against the conveyor belt,
a holding device for the system carrier having at least one attachment part for stationary attachment relative to a belt scaffold of the conveyor belt, a holding element for attaching the system carrier to the attachment part, wherein a supporting element is provided on the attachment part,
wherein the holding element is coupled to the system carrier via a tensioning arrangement, the tensioning arrangement including an adjustable tensioning element, wherein the system carrier can be acted upon with a torque about its longitudinal axis by the tensioning arrangement,
and wherein the holding element is detachably connected to the attachment part, such that
in an operative position, in which the holding element is connected to the attachment part, the system carrier is held on the attachment part via the holding element,
and in a assembly arrangement, in which the holding element is detached from the attachment part, the system carrier having the scraper module and the holding element can be extracted in the longitudinal direction of the system carrier in an extracted position such that when the system carrier is extracted, the scraper module passes the attachment part,
wherein, in the extracted position, the attachment part supports the system carrier via the supporting element.
