Manitowoc has completed the maximum overload test for the 2,300 tonne Manitowoc 31000.
The 31000 successfully lifted a physical test weight of 2,500 tonnes
While fitted with over 600 strain gauges measuring the tension and compression of all key components during the lift.
Kevin Blaney, manager of product marketing for crawler cranes, said: “We'll check the stresses in the structure to verify the preliminary capacities. Then we will correct them up or down or modify structural components to assure that actual stresses are within accepted limits.”
Larry Weyers, senior vice president of the Americas region, added:
“The lift went very smoothly, and our unique Variable Position Counterweight worked perfectly. Exactly as we expected.”
Boom lengths on the 31000 will range from 180 ft to 344 ft. Various fixed and luffing jib setups will also be available.
