Heavy Cranes
A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places.

The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the transport industry for the loading and unloading of freight, in the construction industry for the movement of materials and in the manufacturing industry for the assembling of heavy equipment.

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. Later, larger cranes were developed employing the use of human treadwheels, permitting the lifting of heavier weights.

Harbour cranes were introduced to load and unload ships and assist with their construction in the High middle ages, they were used to built into stone towers for extra strength and stability.

The earliest cranes were constructed from wood, but cast iron, iron and steel took over with the coming of the Industrial Revolution. Modern cranes usually use internal combustion engines or electric motors and hydraulic systems to provide a much greater lifting capability than was previously possible, although manual cranes are still utilized where the provision of power would be uneconomic.
