Replacing the Lifting Table Unit
Parts, equipment and tools
▪ DC/QL lifting table type A [03075652-xx] or
SC lifting table type A - DX4 [03082396-xx]
▪ Depth measuring gauge (200 mm) [03079617-xx]
Overview
Removal
► Use the software to move the conveyor sides to a position which gives you good access to the lifting
table fixtures.
► Switch off the machine and secure it to prevent unauthorized reactivation. Observe the instructions
in section "1.2 Preparatory Work..." [ ➙ 12].
► Loosen the conveyor side clamps. (see "3.6.1 Loosening the Conveyor Side Clamps" [ ➙ 95]).
► Loosen the four screws fastening the two lifting table plates and remove the lifting table plates from
the machine. Make sure that the plates are not swapped over by mistake.
► Mark the positions of the lifting table plate fixtures to make it easier to refit them later on. These fix-
tures are used to set the height and parallelism of the lifting table plates. If these are not reinserted
in exactly the same positions, you will need to totally realign the lifting table plates after installation.
CAUTION
Lifting table motor
The lifting table motor can not be replaced on DC/QL conveyors. In this case you need to re-
place the entire lifting table. Do not take the lifting table mechanism apart.

frame
2. Conveyor control
3. Conveyor control frame
4. Four lifting table plate fixtures
These are part of the lifting mechanism.
5. Lifting table motor
6. Electrical connections for the lifting table motor
NOTICE
Dual and single conveyor
The removal is shown in the diagram using the example of a lifting table unit for the dual con-
veyor (DC). Replacement of the lifting table unit for the single conveyor (SC) is the same.
NOTICE
Lifting table up?
If the lifting table stays in the top position, you first need to disconnect the motor from the rods.
(See "3.6.4.1 Manually Lowering the Lifting Table" [ ➙ 103])
If this is not possible, contact your SIPLACE Service team.

table at the wrong angle later on (turned by 180 degrees).
► Loosen the four screws fastening the lifting table.
► Carefully lift the lifting table out of the machine.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:

CAUTION
Make sure that you do not loosen any other screws!
CAUTION
Heavy machine part!
When removing the lifting table, remember it is heavy. You may need to enlist the help of a sec-
ond person.
CAUTION
Installation instructions
► Make sure that the lifting table is aligned correctly in the direction of transport.
► Before you finally fix the lifting table into place, push it up to the stop in the direction of the
machine outer side (away from the center). This ensures that the lifting table is parallel.
