Vietnam boiling, Kent State fractured and Presidents falling.
Our minds ran numbers with only a slide rule to help.
Still we grew, in numbers and stature-our machines following suit.
The Manitowoc 4100 was an existing crawler crane which needed to lift more.
Engineers defined the need and ran the equations. The solution, black and white, in a era when society ran afoul with the newly discovered shades of grey, continues to stand the test of time.
Spend a little quiet time with this magnificent replica. Notice the straight utilitarian lines and the consistent angles. The solutions; two booms for lifting, counterweights balancing, a wide ring distributing the total weight over a large area and providing stability for those long reaches.
Manitowoc's newer siblings reach higher, lift more. Boom combinations spit out by computers precise as only silicon can be. Beautiful in design, etched for capacity, so efficient the problem is lost deep in the bowls of a mainframe. It is still there, the American ingenuity, it just that, I don't know; it's too pretty?
