Chain (continued)
Length adjustment of the conveyor chain
End drive units, catenary drive units
1 Adjustment of the conveyor chain is carried out at the
drive end of the conveyor.
2 The transmission guard cover must be removed from
the drive unit and the slip clutch disengaged or trans-
mission chain removed. The conveyor chain should
now be free to travel within the conveyor beam profile.
3 Catenary protection plates should also be removed to
allow easy access for the conveyor chain pin insertion
tool.
4 The conveyor chain should be tensioned within the
conveyor system by pulling down the conveyor chain
at the chain catenary in the underside of the drive unit.
Clamp across the conveyor chain to trap the chain on
to the beam profile. The clamp should be placed over
the edges of the drive unit to reduce the risk of dam-
age to the aluminium profile.
5 Remove all slack links from the conveyor chain using
the pin insertion tool.
6 Rejoin the conveyor chain using a new steel pin and
plastic pivot.
7 Remove the chain clamp and replace the catenary
protection plate and transmission chain. The slip
clutch should also be reset.
8 Replace the transmission guard cover. The conveyor
is now ready for operation.
Intermediate drive units, horizontal bend drive units
1 Conveyors which have no conveyor chain catenary
should be assembled with a special section of con-
veyor beam (X..CC), which allows for the chain to be
easily inserted and adjusted for tension. (See previ-
ous page.)
2 Remove the lower part of this conveyor beam section
by releasing the four screws.
3 Lift the chain from this section of the beam and clamp
the conveyor chain as described above. Adjust the
chain tension as for end and catenary drive units.
In a wheel bend drive, the outer aluminium profile can be
removed by slackening the set screws in the beam con-
necting strips. The slide rail must be fitted to allow the
removal of this section.
1 After removal of the outer aluminium profile, the con-
veyor chain can be pulled out of the wheel bend disc.
Lift the chain upwards.
2 Remove chain links using the pin insertion tool.
3 New steel pins and plastic pivots must be used when
rejoining chain ends.
4 The tensioned chain can now be pulled back into
position on the bend guide disc, and the outer profile
put into place.
