OS -- The 4 sets of 747 MLG bogies are there for takeoff and aborts at max weight. Landings, generally at half the weight, can be done on just the body or wing gear -- although a landing on just the body gear is best done with a minimal crosswind.
There is considerable vertical travel on the wing gear oleos; however, the limiting factor in bank is the outer engine pod.
Also the rear axles of the bogies hang down; so, there is a complex gradation of weight transfer from lift to the gear as the various axles and bogies come into contact and the oleos compress.
Bottom line is that the first gear contacting the runway does not immediately assume the entire landing weight -- assuming a reasonable descent rate.
