1.
2. A mobile cranes are machine that could
lift, pull, tug, carry, and do many such
things that are done on a large scale.
It is a cable-controlled crane mounted on
crawlers or rubber-tired carriers or a
hydraulic-powered crane with a
telescoping boom mounted on truck-
type carriers or as self-propelled models.
They are commonly used in the
construction industry and in the
manufacturing of heavy equipment.
3. Ancient Greeks
The first known construction cranes were invented by
the Ancient Greeks and were powered by men or beasts of
burden, such as donkeys. These cranes were used for the
construction of tall buildings
4. Ancient Roman
The heyday of the crane in ancient times came during the Roman
Empire, when construction activity soared and buildings reached
enormous dimensions. The Romans adopted the Greek crane
and developed it further and called tread wheel crane. We are
relatively well informed about their lifting techniques,
thanks to rather lengthy accounts by engineers Vitruvius
5. Middle Ages
During the High Middle Ages, the tread wheel crane was
reintroduced on a large scale after the technology had fallen into
disuse in western Europe with the demise of the Western Roman
Empire. The earliest reference to a treadwheel (magna rota)
reappears in archival literature in France about
1225,followed by an illuminated depiction in a
manuscript of probably also French origin dating to
1240.In navigation, the earliest uses of harbor cranes .

11. Rough Terrain Crane
A crane that is mounted on an undercarriage with four
rubber tires, designed for operations off road. The
outriggers extend vertically and horizontally to level
and stabilize the crane when hoisting. These types of
cranes are single engine machines where the same
engine is used for powering the undercarriage as it is
for powering the crane. In these types of cranes, the
engine is normally mounted in the undercarriage
rather than in the upper portion.
