A tower crane is usually assembled by a telescopic jib (mobile) crane of greater reach (also see "self-erecting crane" below) and in the case of tower cranes that have risen while constructing very tall skyscrapers, a smaller crane (or derrick) will often be lifted to the roof of the completed tower to dismantle the tower crane afterwards ...
Manitowoc lattice-boom crawler cranes was the beginning of Manitowoc Cranes until the major acquisitions in 2001. In 1969, Manitowoc introduced its flagship crane, the Model 4100W. Manitowoc introduced its first self-erecting, all-hydraulic crane, the Model M-250, in 1992.

A level-luffing crane is a crane mechanism where the hook remains at the same level while luffing: moving the jib up and down, so as to move the hook inwards and outwards relative to the base. [ 1 ] Usually the description is only applied to those with a luffing jib that have some additional mechanism applied to keep the hook level when luffing.
A rubber tyred gantry crane (US: rubber tired gantry crane)/ RTG (crane), or sometimes transtainer, is a wheeled mobile gantry crane operated to ground or stack intermodal containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels.
Other crane types, such as gantry or Goliath cranes may have similar capacities, but the jib reach of the ring crane allows them to work over a large area. This ability for a single crane to make lifts over a large area may reduce the amount of other expensive high-capacity plant needed, such as self-propelled modular transporters (SPMT). [6]
