3.2-2 Preparing for crane operation
Working in arm positions up to 60°
Level the vehicle so that the inclination is maximum 3° in every direction.
If the vehicle is secured in a maximum inclination of 3°, the load
lifting gear must not exceed 60°. Due to the reduced guiding function
of the hexagon profile of the extension boom may cause the load
lifting gear to swing to the side and the load to drop.
Working in arm positions beyond 60° (near vertical arm position, cable winch
operation, fly-jib operation)
When working crane position beyond 60° the vehicle has to be completely
levelled. The bubble must be within the inner circle.
If the inclination of the vehcle is greather than 1,5° the load
lifting gear is in almost vertical position may cause the load
arm to swing to the side and the load to drop because of the
reduced guiding function of the hexagon profile of the
extension booms.
