Introduction to drive units
Four types
There are four different types of drive unit: end drive
units, intermediate drive units, catenary drive units and
horizontal bend drive units.
End drive units
End drive unit with return chain, located at the ‘pulling’
end of the conveyor. End drive units are either transmis-
sion chain types (see picture) or direct drive types.
Intermediate drive units
Intermediate drive unit located at an intermediate posi-
tion along the conveyor.
Catenary drive units
Catenary drive unit without return chain, located at an
intermediate position along the conveyor.
Horizontal bend drive units
Horizontal bend drive unit for driving endless conveyors
without return chain.
Chain transmission
The drive units are normally fitted with roller chain trans-
mission. Some end drive units come with direct drive.
Note
The roller chain transmission has chain guards and gear-
ing protection. These guards should always be in position
when the conveyor is in operation.
