<p>An external unit makes a first enquiry as to whether the locks on the container to be lifted are unlocked or not, and also makes a second enquiry relating to the requirements of the locks to be lifted which are in the locked state. These two pieces of information are sent to the external unit or another unit, where it is determined whether the locks are actually locked, and if so, whether they meet the requirements for lifting. If the locks are in the locked state and are capable of being used for lifting the container, then lifting is carried out.</p> |
