An old engraving of a hand-cranked ordnance, bridge crane of the 1800s, found in factories, foundries and yards. It is from a Victorian mechanical engineering book of the 1880s. Here workers are lifting and moving a heavy gun barrel held on chains attached to a ‘crab’ able to move sideways on the moveable beam or bridge. A traveler, traveller hoist, is a type of overhead crane or bridge crane. Here the bridge is supported on legs running on fixed rails – sometimes called a gantry crane or a goliath crane.
An old engraving of a hand-cranked ordnance, bridge crane of the 1800s, found in factories, foundries and yards. It is from a Victorian mechanical engineering book of the 1880s. The crane consists of parallel runways with a travelling bridge spanning the gap. A traveler, traveller hoist, is a type of overhead crane or bridge crane. A hoist, the lifting component of a crane, travels along the bridge. Here the bridge is supported on two sets of legs running on fixed rails – sometimes called a gantry crane or a goliath crane. Here workers are lifting and moving a heavy gun barrel held on chains attached to a ‘crab’ able to move sideways on the moveable beam or bridge.
