3.2.1
Driving with trailer
Observe the applicable national regulations for driving with a trailer.
Operation with a trailer is only permitted if the truck crane is approved for trailer
operation and has been equipped with the appropriate additional equipment (e.g.
trailer hitch) by the manufacturer. More information on driving with a trailer;

Do not exceed the maximum permissible trailer load and drawbar load.
3.2.2
Driving with a dolly
Observe the applicable national regulations and laws for driving with a dolly!
For driving with a main boom set down on a dolly, the truck crane must be
equipped with a slewing gear freewheel and a boom floating position. The truck
crane can also be equipped with a boom pre-tensioning mechanism.
Before driving, always switch on the boom floating position in order that the main
boom can move up and down on bumpy ground. This prevents the dolly from be-
ing partially lifted, which could cause the permissible axle loads on the truck crane
to be exceeded, or the main boom from pressing on the dolly and damaging it.
Before driving, always switch on the slewing gear freewheel in order that the
superstructure can rotate when driving around corners. This prevents the main
boom from shearing out and pushing the dolly off the road when driving around
corners.
If a houselock is fitted, always switch it off before driving. When the houselock is
switched on, the slewing gear freewheel is locked.
