Place both containers on firm ground and spaced correctly to allow the fitting of the container joiners.
Install the container joiners correctly with the engaging handles horizontal and retained by the red locator fingers. Start lifting the containers, taking care to take up chain tension slowly and evenly.
Once the containers are clear of the ground, check to ensure the container joiners and separators are secure in their original location.
Place the two containers onto the Sidelifter centre pair of twistlocks then onto the crane base twistlocks. Lock twistlocks.
It is fine to travel with the joiners left in place, but before lifting the containers off the Sidelifter, ensure the joiners and spacers are still locked in place.
