Chapter 7 Preparing for crane operation
Caution! Not maintaining the minimum distances creates an acute
risk of fatality for the operator and others.
• The operator must have full view of all crane movements.
All safety notes of chapter 2 shall be observed.
Caution! Extending the extension booms before the main boom is in
nearly vertical position causes acute risk of fatality for the operator.
Only extend the extension booms when the main boom has been raised to a near-vertical position. See
‘Unfolding the crane’.
• Move the main boom out of its transport position into working position.
• Make sure that all mechanically actuated functions are properly secured with connection pin and
lynch pin.
