It's strongly recommended to perform maintenance activities according to
the methods described. During maintenance proper and safe tools must be
used. Before disassembling any part please refer to the assembly section
in this manual.
6.2.1 To move the conveyor chain
Follow the below procedure to move the conveyor chain within the Spiral
Elevator:
1 Ensure that the Spiral Elevator is free of products
2 Make sure that the main switch has been switched off, and safely
isolated.
3 Release the brake if present on the gear motor so the chain can
move freely.
4 Depending upon the ratio of the gear motor it may be necessary
to remove the gear motor.
5 Check the conveyor chain moves in the Spiral Elevator smoothly.
.
Note! If the rotation feels very heavy it's possible that the
conveyor chain is jamming somewhere. Check the conveyor
chain and remove any possible obstruction. Make sure the brake
is released.
.
Danger: Make sure that the main switch has been switched off,
and safely isolated, in order that there is no possibility that the
spiral elevator can be started unexpectedly.
