What equipment were used to build hadrians wall?

Answer 1

We do not know which exact equipment was used to build Hadrian's Wall. However, we do know which construction equipment the Romans used .They used an instrument called groma for surveying. They had several types of cranes. The trispastos single-beam projecting arm, a winch, a rope, and three pulleys which could lift 150 kg (330lb.). The pentaspastos had five pulleys and could lift 450 Kg (992 lb.). The Polyspastos could have two, three or four masts with either a winch worked by four men at the by four men at both sides (which could lift 3,000 kg, 6613 lb.) and a treadwheel which could lift 6,000 kg (13227 lb.) with half the crew.

It is known that the Romans were capable of lifting weights of up to 60 metric tonnes. It is thought that one of two techniques was used. One was a lifting tower was with four masts were arranged in a square or rectangular shape and the structure was erected in the middle. In the other there were many capstans on the ground around the tower Capstans had a lower lifting power than treadwheels, but a larger number of them could be used and they could be powered by draught animals if needed. The work of the operators of each capstan had to be co-ordinated very carefully.

Hadrian's Wall was 80 Roman miles (117.5 km, 73.0 miles) long. It was designed to have a mini fort which could host a few dozen soldiers every Roman mile, but their spacing varied slightly due to the terrain. They were made with timber and earth. There were pairs of turrets made with stone at regular distances for observation and signalling. The wall was made with the local limestone, except for its western section which was made with turf because there was no limestone in that area.
