- Ajax is a floating crane built to move and install the canal locks and other large parts of the Panama canal. Ajax also helped in ship repairs and clearing the canal as needed. Ajax and her identical sister crane, the Hercules, were the largest floating cranes at time of completion, able to install the massive Panama Canal locks. Ajax could lift a maximum of 250 tons to a height of 21 feet, with a close reach. At Ajax's far reach she could lift a maximum of 100 tons. Ajax and Hercules were built by Deutsche Maschinenbau AG (1910-1977) (that later became part of Demag, in Wilhelmshaven, Germany).After the Ajax and Hercules, Deutsche Maschinenbau AG later made the Langer Heinrich, or Long Henry in 1915, in use for 100 years. The contract for the two cranes was signed on April 21, 1913. The cranes were of the revolving type, at a cost of about $837,500 each. The two cranes were to be completed in 580 days and delivered to the Panama Isthmus by December 2, 1914, from Emden, Germany. The two cranes arrived in Cristóbal, Colón, Panama on Dec. 7, 1914, several months after their scheduled arrival time of July 1914. Ajax performed an acceptance test before being put into service. Ajax was lifting a 20% over max weight at a far reach test, lifting 120 tons of concrete blocks and iron rails as weights. At 4 feet off the ground the steel framing of the crane's gib failed. The damage to the crane was limited and the repair cost was about $100,000. The Hercules was used to lift the new modified jib framing onto Ajax. The barges Ajax and Hercules had a length of 46.25 m, a width of 27.54 m and a draft of 4.8 m, with a gross tonnage of 4000 Tons. Both use charcoal to fire the boilers. (en)
