A steeplejack is a craftsman who scales buildings, chimneys, and church steeples to carry out repairs or maintenance.
Steeplejacks erect ladders on church spires, industrial chimneys, cooling towers, bell towers, clock towers, or any other high structure. In the UK, steeplejacks now use a belay rope fall-arrest system (similar to the method used by rock climbers) attached to the ladders as they are erected to eliminate solo climbing and greatly reduce the risk of falls from height.
Once ladders have been erected, the next stage is usually to suspend a bosun's chair (a strong wooden plank on which the steeplejack can sit, pull themselves upwards or lower themselves downwards, or sit in a stationary position), but abseiling (UK) or rappelling (US) equipment is replacing the bosun's chair on many operations because of its lighter weight.
Once this has been done it is possible to use this access to begin building scaffolding to carry out any repairs which may be required. This is done by fixing anchors into the wall (whether concrete, stone, or brick) and "kicking" the scaffolding off from there.
It is also possible to carry out repairs from "suspended access cradles". These are the same type of rig window cleaners use on skyscrapers. The cradle is suspended from four wires. Two of these run through an electric motor which can "climb" or "descend" the wire, and the other two run freely through a box which allows the cradle to travel upwards with no obstruction, but will stop it instantly if it starts to fall. These "suspended access cradles" are popularly called "swing stages" by their crews.
Steeplejacks are called upon to repair or replace masonry (brick, stone or concrete), carry out general carpentry or painting or roof repair, remove and clean and repair windows, as well as sandblasting and other masonry cleaning tasks.
In Ontario, Canada, many steeplejacks are represented by Local 598 of the OPCMIA union (Operative Plasterers and Cement Masons International Association of the United States and Canada), and are required to complete a five-year apprenticeship.
In the UK steeplejack companies may be members of the industry association ATLAS (Association of Technical Lightning and Access Specialists). Britain's most famous steeplejack was Fred Dibnah, who became a television presenter and celebrity as a result of his craft and personality. [1] [2]
Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other human-made structures. Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Unsafe scaffolding has the potential to result in death or serious injury. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes and art projects.
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the flue. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships.
A chimney sweep is a person who inspects then clears soot and creosote from chimneys. The chimney uses the pressure difference caused by a hot column of gas to create a draught and draw air over the hot coals or wood enabling continued combustion. Chimneys may be straight or contain many changes of direction. During normal operation, a layer of creosote builds up on the inside of the chimney, restricting the flow. The creosote can also catch fire, setting the chimney alight. The chimney must be swept to remove the soot.
Frederick Travis Dibnah,, was an English steeplejack and television personality, with a keen interest in mechanical engineering, who described himself as a "backstreet mechanic".
