Bulk-handling Crane
A bulk-handling crane is one that, instead of a simple hook that can handle a range of slung loads, has an integral grab for lifting bulk cargoes such as coal, mineral ore etc. Where the grab is a two-piece hinged bucket, it is known as a shell grab or shell bucket. Working the grab requires extra cables from the crane jib, so requires a specialised design of crane throughout, not merely an attachment. Some grabs use 2 cables for lift and control, others use 4. In 1927, Stothert & Pitt of Bath, Somerset produced the first specialised bulk-handling crane. This was to unload coal at Barking power station in London. The grab has to be selected so that the combined weight of grab and contents does not exceed the grabbing safe working load of the crane. The mass of the contents depends upon the properties of the product being handled; its density, flow characteristics, angle of repose, lump/grain size, purity (e.g. is it wet or dry) and, in some cases, degree of settlement (e.g. a s ...

Crane (machine)
A crane is a type of machine, generally equipped with a hoist (device), hoist rope, wire ropes or chains, and Sheave (mechanical), sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy objects and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian technology. Construction cranes later appeared in ancient Greece, where they were powered by men or animals (such as donkeys), and used for the construction of buildings. Larger cranes were later ...

Stothert & Pitt
Stothert & Pitt was a British engineering company founded in 1855 in Bath, England. It was the builder of various engineering products ranging from Dock cranes to construction plant and household cast iron items. It went out of business in 1989. The name and intellectual property became part of Clarke Chapman. History George Stothert (n.b. early on the name is sometimes rendered as Stoddard or Stodhert) moved to Bath in 1785 having taken over Thomas Harris's ironmonger's business. He was an agent for Abraham Darby I's Coalbrookdale Iron Company, selling all types of domestic ironmongery. By 1815 they set up their own foundry as Abraham Darby had opened his own warehouse in Bristol. The company was now managed by his son, also George. In 1851 they exhibited a hand crane at the Great Exhibition. In 1837, Henry Stothert, brother of the younger George, set up an ironworks in Bristol, first as ''Henry Stothert & Co.'', then, joined by Edward Slaughter, Stothert, Slaughter & Co. ...

Barking Power Station
Barking Power Station refers to a series of power stations at various sites within the London Borough of Barking and Dagenham in east London. The original power station site, of the coal-fired A, B and C stations, was at River Road, Creekmouth, on the north bank of the River Thames. These stations were decommissioned by 1981 and were subsequently demolished. The later gas-fired power station (originally generally known as Barking Reach Power Station) was built further down the Thames near Dagenham Dock in the early 1990s. The site of the former power stations is being redeveloped as Barking Riverside. History Barking A power station Prior to the construction of Barking A Power Station, Barking Town Urban District Council operated its own small power station near its offices from 1897 until its closure in 1927. In 1920, the County of London Electric Supply Company applied for permission to build a power station at Creekmouth in Barking capable of expansion to 600 MW. The B ...

Coal Loading Shell Grabs, Cardiff
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
