6. Lock the control levers securely with the safety lock lever (4) to
the lock position.
7. Install shackles at two locations (A) on the crane boom and two
locations (B) on the crane frame, to hook the hoisting wire rope
in a manner such that the hoisting angle is “60 degrees or less”.
NOTES
The hoisting hook should come to the center of the gravity at this
point.
8. Verify that there is no posture change caused by the leakage
from the hydraulic circuit on the derricking cylinder head side
when the machine is hoisted.
9. After the machine left the ground, verify the hook condition and
hoisting posture. Then slowly hoist the machine.
NOTES
When the crane is hoisted in the above posture, it inclines about
“1 degree” backward.
