Action
Attach the Lifting accessory (chain) to an over-
head crane (or similar), then to the lifting eye in
the arm house and to a roundsling run through
the wrist.
Adjust the chain lengths to make the lift as level
as possible.
Raise the overhead crane to stretch the chains
and roundslings.
Verify that the roundsling between the wrist and
the lower arm is stretched.
Note
Keeping the cable harness and DressPack fitted on the robot during gearbox
replacement is only a recommendation. If it is not possible to put the lower and
upper arm close enough to the robot, the cable harness and DressPack in the
base and in the frame must be removed first.
