Removing Or Changing Fixtures - ABB IRBP Product Manual

3.9.2 Removing or changing fixtures

Introduction
If there is a difference between the loads on each side of the positioner IRBPK,
then special care must be taken when removing or changing fixtures or workpieces.
Load difference sides 1 and 2 does not exceed specified maximum value
If the positioner is in a horizontal position or not at the end of the working range
when removing or changing fixtures, make sure that the value of Max load difference
sides 1 and 2 is not exceeded.
Fixtures can be installed in any positioner position.
Load difference sides 1 and 2 exceeds specified maximum value
If the weight of the fixture exceeds the value of Max load difference sides 1 and 2,
run the positioner to the working range end when positioner side 2 is oriented
towards the operator side (positioner side 1 is toward the welding robot). Then the
positioner cannot move further downwards when the first fixture is removed.
