Either you, or the movers, need to visit the town police in Morges and arrange for them to put out the no parking signs. The police usually need about 3 days notice and charge a fee. They might need to know the length of the delivery truck (70 feet plus?). http://www.police-region-morges.ch/en/
I expect it is this office Other Police Departments
(Management, fines, lost&found, trade activities, parking, traffic signs et local Court), Place Saint-Louis 2:
I have just gone back and read the post again, and as it is a private road, you should speak to the landlord. How are other owners going to reach their property if the truck is blocking the lane?
Maybe the truck will have to park on the public road and they must carry all the stuff to your home?
