The first element of the tower crane is the base. The base is made of large concrete pad, that is prepared several weeks before the tower crane comes to the construction place. The pad is usually 30 feet by 4 feet, like 10x10x1.3 meters and it weights more that 400,000 pounds. The mass is lattice structure, typically 10 feet square. That is like 3.2 meters. The trianglated cross-members structure gives the mast the strength to remain upright.

The tower crane arrive at the construction site on a 10 to 12 tractor trailer rings. The crew uses a mobile crane to assemble a 40 foot mast that consist of two vertical mass section and the slewing gear.Then the jib and the machinery sections are assembled.
