3.3 - Arrangements According to the requirements of the speciﬁc project, different arrangements of transoms have been designed. These may be separated into ﬁxed and suspended transoms. In belt conveyors there are two basic types of troughing sets: that of the carrying set, which supports the belt on the loaded section, known as the upper troughing set; and that of the return set, which supports the empty belt on its return section. A particular category of troughing sets is that known as the impact set which is positioned to correspond to the section where the belt is loaded with material.

This assists the belt tracking by an autocentralising effect. For reversible belts the version R is required, which is without the above two degrees (see “order codes” par
