3.2-2 Preparing for crane operation
Working in arm positions up 60°
Level the vehicle so that the inclination is maximum 3° in every direction.
When the vehicle stands in a maximum inclination of 3° then the
angle of 60° must not be exceeded with the load-bearing arm.Due to
the reduced guiding function of the hexagon profile of the extendable
arm this may cause the load-bearing arm swinging to the side and
the load being dropped.
Working in arm positions beyond 60° (near vertical arm position, rope 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.
When the vehicle is more than 1,5° inclined during loading
works in near vertical position this may cause the load arm
swinging to the side and the load being dropped because of the
reduced guiding function of the hexagon profile of the
extendable arms.
