Quarterly check of the efficiency of the brake of the rotation arm of the crane:
•
Check the stability of the arm when empty and when fully loaded, at the end points and
intermediate points of rotation; then checking that the arm, in any point of the rotation, keeps its
position with moving spontaneously.
•
When necessary have the brake of the crane adjusted, as described in paragraph 6.4.1
