Action
Alternate method of lifting:
Fit the lifting tool 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.
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!
Refit the robot to the base with its attach-
ment screws and serrated lock washers.
Note
The orientation of the serrated lock washer
must be fitted as is shown in the figure to
the right!
