Heavy loads cannot be handled with the boom straight.
Set the second boom, so there is an angle in relation to the
first boom.
Loads at the extreme limit of the working zone
Also in this case, angle down the second boom somewhat.
Only use the first boom .
TIP
Make smooth crane movements: operate the crane with various functions simul-
taneously. In this way you will also prevent the hydraulic system heating up
quickly.
