Tower crane, from EN Wikipedia,cc-by-sa

A tower crane at a construction site in south London. The crane shows typical space frame design in which the strength comes from the triangular arrangement of struts. In this instance the main lifting boom is pivotted and has an adjustable angle, rather than the more common horizontal boom.

Note the operators cabin on the right of the junction with the main tower, and the slabs of concrete acting as a counterbalance on the left.
