The awesome feats the humble crane can reach are certain to have the amazement of people in the know. They are said to have originated in ancient Greece while the ancient Romans are known to take credit for all of the progress in the design of their cranes.

Archaeologists think that cranes were seen in 4th century BC when a simple pulley using what is now named Lewis irons were used for the construction of major Greek Temples and constructions. Then came in the traditional winch and pulley system that changed the manner Greek temples were constructed afterward.

The upcoming monumental break in the Cable technologies came through the time of the Roman empire which saw the first use of these treadwheel cranes and easy winch pulley combinations that raised the lifting capability of an individual using the pulley to 3,000 kg. Afterward, pulleys were designed to have a lifting capacity of up to 60 tonnes.

Then came in the picture that the industrial revolution that radically changed how cranes were used and designed. With the start of the industrial revolution, iron became the preferred metal for producing the cranes unlike the past when ropes were the favored medium. With the creation of the hydraulic crane, everything changed about how heavy loads were lifted and moved. The new hydraulic cranes were shown to be a lot more effective for all heavy lifting and transferring projects particularly close to the waterfront locations.
