Overhead Traveling Crane
An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap. A hoist, the lifting component of a crane, travels along the bridge. If the bridge is rigidly supported on two or more legs running on two fixed rails at ground level, the crane is called a gantry crane (USA, ASME B30 series) or a ''goliath crane'' (UK, BS 466). Another variant is the ''semi-goliath crane'', where one fixed rail is at ground level, and the other fixed rail is overhead, commonly used along the exterior of an existing building. Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime are critical factors.

Liverpool
Liverpool is a port City status in the United Kingdom, city and metropolitan borough in Merseyside, England. It is situated on the eastern side of the River Mersey, Mersey Estuary, near the Irish Sea, north-west of London. With a population of (in ), Liverpool is the administrative, cultural and economic centre of the Liverpool City Region, a combined authority, combined authority area with a population of over 1.5 million. Established as a borough in Lancashire in 1207, Liverpool became significant in the late 17th century when the Port of Liverpool was heavily involved in the Atlantic slave trade. The port also imported cotton for the Textile manufacture during the British Industrial Revolution, Lancashire textile mills, and became a major departure point for English and Irish emigrants to North America. Liverpool rose to global economic importance at the forefront of the Industrial Revolution in the 19th century and was home to the Liverpool and Manchester Railway, firs ...

Containment Building
A containment building is a reinforced steel, concrete or lead structure enclosing a nuclear reactor. It is designed, in any emergency, to contain the escape of radioactive steam or gas to a maximum pressure in the range of . The containment is the fourth and final barrier to radioactive release (part of a nuclear reactor's defence in depth strategy), the first being the fuel ceramic itself, the second being the metal fuel cladding tubes, the third being the reactor vessel and coolant system. Each nuclear plant in the United States is designed to withstand certain conditions which are spelled out as "Design Basis Accidents" in the Final Safety Analysis Report (FSAR). The FSAR is available for public viewing, usually at a public library near the nuclear plant. The containment building itself is typically an airtight steel structure enclosing the reactor, normally sealed off from the outside atmosphere. The steel is either free-standing or attached to the concrete missile shiel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lifting Beam
The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another. The bottom of the beam has multiple connection points for hanging the load. The lifting beams are used in multiple cases: * lifting an asymmetrical load. Without a beam, it might be hard to strap the load so that its center of gravity is exactly below the hook; * handling a long load with a single-hook crane. Sufficient spread between the slings prevents the load from slipping out; * increase the headroom: slings cannot be stretched close to the horizontal direction, so attaching them directly to the hook requires a minimum distance from the hook to the load. When the lifting beam is used, the slings can be shorter, providing more vertical clearance during lifting; * if the attachments of the load are on its vertical sides, the slings have to go over the edges of the load, ...

Warehouse
A warehouse is a building for storing goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, transport businesses, customs, etc. They are usually large plain buildings in industrial parks on the rural–urban fringe, outskirts of cities, towns, or villages. Warehouses usually have loading docks to load and unload goods from trucks. Sometimes warehouses are designed for the loading and unloading of goods directly from railways, airports, or seaports. They often have crane (machine), cranes and Forklift truck, forklifts for moving goods, which are usually placed on International Organization for Standardization, ISO standard pallets and then loaded into pallet racking, pallet racks. Stored goods can include any raw materials, packing materials, spare parts, components, or finished goods associated with agriculture, manufacturing, and production. In India and Hong Kong, a warehouse may be referred to as a godown. There are also godowns in the Shanghai Bund. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ictineu 3
''Ictineu 3'' is a crewed submersible capable of reaching depths of 1,200 m (3,900 ft), which makes it the ninth deepest submersible, owned by Ictineu submarins SL. Commissioned in 2013, the submersible can carry one pilot and two passengers for 10 hours using all the equipment. The small weight and dimensions of the submarine (4.8 x 1.9 x 3 m) allow the Ictineu 3 to be carried with a conventional truck without requiring special transportation. The main body is made of inox steel and, at the front, there is a large semi-spheric acrylic glass viewport of 1,200 mm diameter that provides a wide field of view. There are four brushless DC motors for propulsion and four more for manoeuvring, powered by li-ion batteries located outside the submersible for safety. Its applications range from submarine archaeology to industrial work, and it is specially designed to be easy to adapt to new technology and equipment, having additional ports for wires, sensors and tools. It can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submersible
A submersible is an underwater vehicle which needs to be transported and supported by a larger ship, watercraft or dock, platform. This distinguishes submersibles from submarines, which are self-supporting and capable of prolonged independent operation at sea. There are many types of submersibles, including both human-occupied vehicles (HOVs) and uncrewed craft, variously known as remotely operated vehicles (ROVs) or unmanned underwater vehicles (UUVs). Submersibles have many uses including oceanography, underwater archaeology, ocean exploration, tourism, underwater work, equipment maintenance and underwater search and recovery, recovery and underwater videography. History The first recorded self-propelled underwater vessel was a small oar-powered submarine conceived by William Bourne (mathematician), William Bourne (c. 1535 – 1582) and designed and built by Dutch inventor Cornelis Drebbel in 1620, with two more improved versions built in the following four years.Konstam (201 ...

Electric Overhead Traveling Crane
Electric overhead traveling cranes or EOT cranes are a common type of overhead crane, also called bridge cranes. They consist of parallel runways, much akin to rails of a railroad, with a traveling bridge spanning the gap. EOT cranes are specifically powered by electricity. Applications EOT cranes are extensively used in warehouses and industry. An EOT crane is able to carry heavy objects to anywhere needed on the factory floor, and can also be used for lifting. However, it cannot be used in every industry. The working temperature is to limited to a range between -20°C to 40°C.

Pulley
Sheave without a rope A pulley is a wheel on an axle or shaft enabling a taut cable or belt passing over the wheel to move and change direction, or transfer power between itself and a shaft. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain. History The earliest evidence of pulleys dates back to Ancient Egypt in the Twelfth Dynasty (1991–1802 BC) and Mesopotamia in the early 2nd millennium BC. In Roman Egypt, Hero of Alexandria (c. 10–70 AD) identified the pulley as one of six simple machines used to lift weights. Pulleys are assembled to form a block and tackle in order to provide mechanical advantage to apply large forces. Pulleys are also assembled as part of belt and chain drives in order to transmit power from one rotating shaft to another. Plutarch's ''Parallel Lives'' recounts a scene where Archimedes proved the effectiveness ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crewe Works
Crewe Works is a British railway engineering facility located in the town of Crewe, Cheshire. The works, which was originally opened by the Grand Junction Railway in March 1843, employed around 7,000 to 8,000 workers at its peak. In the 1980s much of the engineering works were closed. Most of the site has been redeveloped, but the remaining parts are owned and operated by Alstom. During the late 19th century, the London and North Western Railway used Crewe Works to produce many famous locomotives such as the Webb Jumbo class and the compounds, the Whale Experiment and Precursor classes, and the Bowen-Cooke Claughtons. In particular, Whale's 1912 superheated G1 Class developed from a locomotive introduced by Webb in 1892, lasted, in many cases until 1964, near the end of steam in 1968. After grouping, the works were taken over by London, Midland and Scottish Railway which was the successor to the LNWR. It was during this period that the works reached its zenith in si ...
