Action
Alternate method of lifting:
Fit the lifting device and a roundsling on the
upper arm and a roundsling with a hoisting
block, to the wrist unit.
Also fit a separate roundsling between the
wrist and the frame in order to eliminate any
load through the brake on motor axis 3.
The hoisting block is used to balance the
upper arm.
See the lifting instructions.
Note
The brake on axis 3 shall be released during
the lift, until the roundsling between the wrist
and the frame transfers the load of the
frame.
See figure to the right!
CAUTION

All lifting equipment used must be sized ac-
cordingly!

Make sure the lift is done completely level.
Adjust the length of the chains as detailed
