Abstract

A removable cartridge cleaner assembly is provided that has an insertion device for ease in installing an elongate cartridge assembly carrying belt cleaner assemblies onto an elongate support extending across a conveyor belt in an operative position thereon. In one form, an elongate lever handle pivotally connected to the elongate cartridge assembly can be used to generate a leveraged insertion force, preferably by an operator that does not need to reach into the operating envelope of the conveyor system, e.g. beyond tensioning mechanisms or under the belt. The handle and the cartridge assembly can have an over center locking mechanism therebetween for providing the operator tactile feedback as to when pivoting of the lever handle has caused the cartridge assembly to be shifted to its operative position on the support.
