Does the 744F have the required restraint points to secure this type of heavy wheeled/tracked load? If I recall, the rules (that I worked to in UK MoD) say you would apply sufficient restraint to cope with a 4G acceleration forward, 3G aft etc.
If the load was secured correctly, it should probably still be restrained to the floor of the crashed aircraft.
Sounds like the type of load that should be in a C5 or C17 where all the tools needed to apply that are available as a/c role equipment.
