Hi Brillo,
Here is where you can download two manuals in PDF form:
http://www.shipsim.com/ShipSimForum/index.php/topic,2886.0.html (http://www.shipsim.com/ShipSimForum/index.php/topic,2886.0.html)
INFO.pdf gives instructions for operating the container crane. The ME tutorial gives additional information on missions that use the crane.
Regards,
Marty
