I saw this documentary on ancient buildings like the pyramids and it said that we don't have a construction crane that can life the stones used to build some of these ancient structures.So I gotta wonder how much the strongest crane CAN lift....or is that just fantastical nonsense about cranes not being able to lift those blocks?
First, okorder /. This means that at 5 m the capacity is 600 tonnes. Double the radius, half the capacity. A crane located at the foot of the pyramid, will be at 115.2 m from the center. At that radius, the crane could only lift 26 tonnes, so this crane could not lift the greatest stones weighing 80 tonnes. Being the boom only 100m it could'nt even reach the center.
Those stones are small compared to what cranes can lift. I did find this Liebherr the heavy equipment company have developed a new all terrain nine axle mobile crane that is the worlds most powerful. The Liebherr LTM 11200-9.1 has a maximum lifting capacity of 1,200 tons with its powerful 100 metre (328 ft) telescopic boom. another: Deira City Centre was the crane’s first lift as it assisted in completing the work in less than 30 hours in what would have otherwise taken an approximate 20 days. The monster machine can lift up to 1,200 tonnes and cover an area over 100m wide. The operational weight is 96 tonnes and the total counterweight is 202 tonnes. Average weight of the stones in the Great pyramid is 2.5 tonnes. So either of those cranes could lift over 400 of these at once.
