Action
CAUTION
The gearbox weighs 160 kg.
All lifting accessories used must be sized
accordingly.
Attach the lifting accessories to the gear-
box.
Attach a roundsling to the lifting accessor-
ies.
Attach the roundslings to an overhead
crane (or similar) and raise to take the
weight of the gearbox.
Lift the gearbox off.
DANGER
Never remove both the axis-2 and axis-3 gearboxes at the same time! One of
the gearboxes must stay fitted when the other is replaced. If not, the complete
arm system will not have any secure connection to the frame and thereby be a
great security risk. A serious accident will most probably happen.
Note
The attachment screws that secure the gearboxes to the lower arm or to the
parallel arm, are arranged in three areas, with 15 screws in each area. It will not
be possible to reach all screws with the robot in only one position. Removal and
refitting must be performed with the robot in more than one position. These
positions are described in the procedures.
