A massive LR 13000 crawler crane lifted three other cranes (totaling 1,430 tonnes) in this product demonstration by heavy equipment manufacturer Liebherr. The demonstration began with Liebherr’s smallest crawler crane, the 62 tonne LR 1100, lifting a toy train. The LR 1100 was then lifted by the 288 tonne LR1350, which was then lifted by the 1,080 tonne LR11350 which was then lifted by the LR 13000. According to the manufacturer, the LR 13000 is the largest crane of its kind. The demo occurred in June during an open house event at the Liebherr factory in Ehingen/Donau, Germany.
As we feel the lift, we might recall that it was on this date in 1936 that Henry F. Phillips received several U.S. patents for the Phillips-head screw and screwdriver. Phillips founded the Phillips Screw Company to license his patents, and persuaded the American Screw Company to manufacture the screws. General Motors was convinced to use the screws on its 1937 Cadillac; by 1940, virtually every American automaker had switched to Phillips screws.
