Many people think of Bath as a city of Georgian terraces but for centuries it has also been a hive of industry.
During the 20th century, Stothert & Pitt were one of the world most successful manufacturers of cranes.
Two revolutionary inventions where key to their success: In 1912 they introduced a level-luffing crane that kept the hook at the same height as goods are moved.
Then in 1927 they introduced the first bulk-handling crane which uses a grabber mechanism instead of a simple hook.
By the 1950s this factory was the biggest employer in Bath with around 2,300 employees.
