◙ Evolution of a Crane and Hoist in Ancient Rome

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?

Ancient Rome Books

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)

My Lovely Days in Lisbon

Enjoying Lisbon fron the First Day

I’m going to tell you my lovely days in Lisbon, which was the capital of an empire. All lisboa remembers his glorious padado. Like when sailors came out to discover and conquer lands on the other side of the world.

You see old faded tiles on their facades. Peeling walls and stone streets lined with old trams. No great luxuries or European stores are sought in this city, although they do. What is sought and found is a melancholic beauty, art, imperfection and the charm of the people.

Traveling with oxygen requires advanced planning

Travel planning can be especially stressful for people with COPD

Traveling with oxygen requires advanced planning

 

See original article: Harvard Health Publishing from Harvard Medical School.

Travel planning can be especially stressful for people with COPD (chronic obstructive pulmonary disease) or other health conditions that require oxygen therapy. The following steps can be helpful with the process:

  1. Call your local oxygen supplier one to two weeks in advance to arrange for your oxygen supply while you are traveling. Your needs will vary according to your mode of transportation and length of stay at your destination.
  2. If traveling by air, book far in advance because airlines allow only a limited number of people traveling with oxygen per flight.
  3. Take antiseptic hand-washing packets or gel to help avoid picking up bacterial or viral infections. Also wash hands with soap and water frequently.
  4. If you are traveling to an area of high altitude, plan ahead for an oxygen supply at your destination.

To learn more about diagnosing and living well with COPD, read Chronic Obstructive Pulmonary Disease: Treating emphysema and chronic bronchitis, a Special Health Report from Harvard Medical School. Traveling with oxygen requires advanced planning

Tips to Travel Venice and be a Respectful Tourist. Survive the Overturism

In April 2017, the Ministry of Interior of Italy put into effect a so-called “Daspo Urban” law. This law allows police forces to restrict access in certain areas of the localities to individuals considered a possible threat to public order, morals or public decency. This is without necessity without the need for evidence of crime. This applies to vagabonds, but it also began to be applied to tourists within certain areas. Article 9 of the decree establishes a monetary penalty of 100 to 300 euros and an expulsion order from the place where the heho occurred and against any person. This expulsion can be for 48 hours and the recidivism reaches much higher penalties.
