Maintenance instruction
After approx. 3 months operation in one shift, the conveyor shall be checked.
The following items shall be special attended.
1) Belt tension.
2) The chain and its position in the frame.
3) The rollers.
It can be necessary to retighten the belt. The frame and the chain should be checked for eventual
excessive wear. The rollers should be easy to move and should run freely. If necessary, the
rollers should be greased.
The belt must be in the middle of the frame to avoid unnecessary wear. When tightening the belt,
check that it will come in the middle of the frame, otherwise the shaft will not be in a straight
angle to the conveying direction. The belt must then be tightened (untightened) with the
tightening device, so that the belt will come into its correct position.
The conveyor must be checked in intervals. Damaged parts must immediately be replaced,
otherwise the function of the conveyor will be disturbed and even other parts can be damaged,
e.g. the belt and the frame.
Belt tightening
Proceed as follows by tightening the belt:
1.
Loosen the screws (16) on the bearing plate (8) and the motor plate (5).
2. Tighten or untighten with the tightening screws (17).
3. Tighten the belt so much that it is possible to press it down about 5-10 mm just before the tail
end.
4. If it is not enough to tighten the belt with the tightening device, it is necessary to take away 2
hinges (see belt disassembly).
5. After the tightening of the belt, the screws mentioned in item 1 above shall be fastened.
NB! We recommend to take extra care in checking the belting and to follow the procedure above
when tightening. If the belt is tightened too hard or too loose, both conditions can cause
problems in operation and damage the belt and the conveyor itself.
