The horizontal part of the crane (the top of the 'T') is assembled on the ground first then jacked up for the first section of the tower to be inserted. The assembly is continually jacked up allowing more and more sections to be slotted in until the required height is reached. Some towerblocks are built in a similar way with the roof first being assembled at ground level then jacked up for floors to be built below. These are known in the UK as "jack blocks" but I'm not sure whether this is an official term or an international one for that matter. Alasdair Bailey

Simple. You must divide 20 by three since there are three feet in a yard. Therefore, your answer is 60 feet.
It is not likely that a tall building would be measured in kilometers. Actually the tallest building in the world is only 829.8 meters which is known as Burj Khalifa in Dubai. Buildings are commonly measured in feet or meters.
Articulated structures like bridges or cranes are typically erected through a carefully planned construction process. This involves assembling individual components, such as beams and columns, on site using cranes and other machinery. Precise engineering and design are necessary to ensure proper alignment and stability during erection. Safety measures, like securing the structure and using proper equipment, are also vital throughout the erection process.
Building a column has nothing to do with cars, which are for transporting people. They moved the stone drums which made up the columns by water transport and on rollers. The erected them with cranes lifting and stacking them on each other.
It's a building with no basement. The building is erected on a concrete "slab" or pad.

Gantry cranes are designed to lift extremely heavy products. Some Gantry cranes are extremely large and are used for ship building. These cranes straddle the ship allowing for large objects to be lifted or moved over the ship.
