G
Risk of accidents when driving with a lifted load
When driving with a lifted load, you must be able to operate the crane at
any time in the event of an emergency. That is why the truck crane may not
be driven from the driver's cab with a lifted load.
G
Risk of accidents when driving with a lifted load
Secure the load when driving so that it cannot swing and use the transmis-
sion mode DM or RM so that the transmission does not shift.
In this way you can prevent the swinging load leaving the permissible
working range and the truck crane overturning.
