3. 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 tranfers the load of the frame.
See figure to the right!
Art. no. is specified in Required
equipment on page 166.
Make sure the lift is done completely
level! How to adjust the lift is described in
the enclosed instruction to the lifting
device! Follow the instructions before
lifting!
Releasing the brakes is detailed in section
Manually releasing the brakes on page
