Evolution of a Crane and Hoist in Ancient Rome

Ancient Rome Crane
Ancient Rome Crane

 

The Roman Empire invested a lot of time, effort and money developing new cranes for the construction of their buildings, bridges and especially aqueducts. They took the Greek’s crane as a model and improved it.

Tripastos in Ancient Roman Empire

In fact, the simplest Roman crane was the Tripastos. It consisted of a single beam jib, a lathe, a rope, and a block containing three pulleys. By maintaining a multiplication ratio of 3 to 1, a single crane operator could raise 300 lbs.


Pentaspastos

A more advanced type of crane was the Pentaspastos which had five pulleys. Moreover and even more sophisticated than the Pentaspastos, was the Polyspastos, which had 15 pulleys and up to four masts with a ratio of 60 to 1.

The Polyspastos, indeed, had four operators per side of the lathe, and it could have a maximum load lifting capacity of 6000 pounds accounting for the maximal effort per operator of 100 pounds each. In case the winch was replaced by a drum, it would double its capacity to 12000 lbs.

However some buildings contained stone’s blocks of more than 100,000 lbs. How could they lift these loads more than 30 yards high?

Roman Empire Engineers. Crane & Hoist

The Roman engineers managed to raise these weights using a diversity of winches. Although winches have a lower multiplication factor of forces than those driven by drums, Romans could have installed more quantity of winches operated by men or even animals. This kind operation a great coordination was required between the working groups that operated the capstans.

The cranes were almost always operated by slaves who were designed for these industrial jobs. In fact, they were assigned in the so-called squads which had a technical head, the praepositus.

 

Marco Vitruvio Polión : Roman Crane & Hoist Architect

(in latín Marcus Vitruvius Pollio; c. -70 BC. -15 BC )

Marco Vitruvio was the author of a book, known today as The Ten Books of Architecture, a treatise written in Latin and ancient Greek about Architecture. It was dedicated to the Emperor Augustus.

In this book he describes different types machines such as forklifts, cranes and pulleys used for engineering structures. It also contained descriptions of war machines like catapults, crossbows and siege machines.

As he was an engineer, Vitruvio was not only doing a description of the machines itself but he might probably have built and tested them.

Roman Cranes = Medieval Treadwheel Cranes

The Roman crane  ( treadwheel crane) almost unchanged or modified will be used until the modern age and in some cases until the mid-nineteenth century as in the ports of Germany. Some are still today in their original places of construction. As an example we will put the Cathedral of Strasbourg (France) and the Church Beverley Minster (England)

A Little History of Roman Roads

The Roman road was the road model used by Rome for the construction of its Empire. The road network was used by the army in the conquest of territories. Large forces could be mobilized with a speed never seen before.
He played a fundamental role in the economy because the transport of goods was significantly improved. The roads also had great influence in the diffusion of the new culture and in spreading the Romanization throughout the Empire.
The Itinerary of Antonino, of the 3rd century, is the written source that gives us more information about the Roman road network.

The roads united the cities of all points of the empire both military, turistic, commercial or administrative.  The trips were easy and fast for the time, with an organization that favored a comfort for its users. Thought, in principle for military use, will be the origin of the economic expansion of the Empire. They also facilitated their fall, since the invading barca towns used them for the conquest of the empire
