Action
Fit a lifting eye in the arm house, with a
fender washer underneath.
CAUTION
The complete upper arm (including the
wrist) weighs 200 kg.
All lifting accessories used must be sized
accordingly!
Attach the upper arm lifting accessory to
an overhead crane (or similar) and then to
the lifting eye in the arm house and in the
wrist.
Raise the lifting accessories to take the
weight of the upper arm.
In case of necessary adjustments, use the
shortening loops on the lifting accessory
(chain), making sure to place the chain the
right way through the loops!
Release the brakes in order to find the most
level lifting position of the upper arm as
possible, before lifting.
In order to release the brakes, connect the
24 VDC power supply.
Action
Before removing the motor, check that the
axis-3 gearbox is completely drained.
