Transport
When transporting the machine on atrailer or other means of transportation, secure it safely. During transport, the machine must be secured so
that it is able to counteract aforward force that is equal to the full total weight as well as to the rear and sides that is equal to at least half the total
weight. We recommend using tensioning straps since standard ropes are unsuitable because they can stretch when subjected to heavy loads. Check
the condition of the tensioning straps and replace them if damaged. Apply the parking brake and switch o the main power switch. During machine
transport, the crane arm should always be in the parked position and locked. Please make sure you have the requisite driving license qualications
that apply for your transport vehicle. Normally, the machine should rest on all eight wheels.
