30-465: Aveling-Barford was a large engineering company making road rollers , motorgraders , front loaders , site dumpers , dump trucks and articulated dump trucks in Grantham , England. In its time, it was an internationally known company. Aveling-Barford underwent a dramatic revival. First established in 1850 its owners incorporated a limited liability company on 16 July 1895 to hold the business with

60-530: A 36-acre site, Invicta Works, on long-term lease (to 2009) from Ruston & Hornsby at Grantham . On the board of directors were Edward James Barford and William Geoffrey Barford (from Barford & Perkins), and John Heinrich Wulff Pawlyn, a director of Ruston & Hornsby based at the Ransomes subsidiary in Ipswich , and George Ruston Sharpley, the managing director of Ruston & Hornsby. For many years all

90-552: A grader and a water truck to achieve the desired flat surface with the correct moisture content for optimum compaction. Once the road base is compacted, the smooth single drum compactor is no longer used on the road surface (there is an exception if the single drum has special flat-wide-base tyres on the machine). The final wear course of asphalt concrete (known as asphalt or blacktop in North America, or macadam in England )

120-541: A new factory in Newcastle upon Tyne was opened. In 1967 it became part of British Leyland . British Leyland engines were to be used as part of the deal, but there were reliability problems. In 1975 Aveling-Barford became Aveling Marshall after BLMC acquired Marshall-Fowler . The company was bought in December 1983 by American businessman Reid Eschallier (3 December 1934 – 13 July 2007) from Pennsylvania . In 1979,

150-1258: A smooth surface. The pads aid in compression, due to the smaller area contacting the ground. The roller can be a simple drum with a handle that is operated by one person and weighs 45 kilograms (100 lb) or as large as a ride-on road roller weighing 20 tonnes (20 long tons; 22 short tons) and costing more than US$ 150,000. A landfill unit may weigh 54 tonnes (53 long tons; 60 short tons). Drums are available in widths ranging from 610 to 2,130 millimetres (24 to 84 in). Tyre rollers are available in widths ranging up to 2.7 metres (8.9 ft), with between 7 and 11 wheels (e.g. 3 wheels at front, 4 at back): 7 and 8 wheel types are normally used in Europe and Africa; 9 and 11 in America; and any type in Asia. Very heavy tyre rollers are used to compact soil. KEY: Bauma (trade fair) 48°08′08″N 11°41′55″E  /  48.1355°N 11.6986°E  / 48.1355; 11.6986 The bauma (International Trade Fair for Construction Machinery, Building Material Machines, Mining Machines, Construction Vehicles and Construction Equipment)

180-401: A total gross area of 20,000 m , attracting around 8,000 visitors. Two years later, the exhibition space had already doubled and the name “bauma”, which is still used today, was introduced. In the early days, the fair was a purely German exhibition. In 1958, the first exhibitors from abroad (number: 13) took part in bauma. Due to the building boom the exhibition space quickly became too small and

210-469: A vibrating roller. The double cylinder or compound steam rollers became popular from around 1910 onwards and were used mainly for the rolling of hot-laid surfaces due to their smoother running engines, but both cylinder types are capable of rolling the finished surface. Steam rollers were often dedicated to a task by their gearing as the slower engines were for base compaction whereas the higher geared models were often referred to as "chip chasers" which followed

240-512: Is both the largest trade fair in the industry and the biggest trade show in the world. The past Bauma edition that took place from April 11 to 17, 2016 attracted 3,425 exhibitors from 58 countries (2013: 3,421 exhibitors; 2010: 3,256 exhibitors) and 583,736 visitors from 219 countries (2013: around 535,065; 2010: around 420,170). The exhibition space was 605,000 m² (2013: 575,000 m²; 2010: 555,000 m²). Both German and foreign suppliers of machinery and vehicles for construction and mining exhibit at

270-442: Is laid using a paver and compacted using a tandem smooth drum roller, a three-point roller or a pneumatic tyre roller. Three point rollers on asphalt were once common and are still used, but tandem vibrating rollers are the usual choice now. The pneumatic tyre roller's kneading action is the final roller to seal the surface. Rollers are also used in landfill compaction. Such compactors typically have padfoot drums, and do not achieve

300-575: Is the world's largest trade fair in the construction industry. The trade fair, which can be visited by anyone, is held every three years on the grounds of the Neue Messe München and lasts for seven days. Its organizer is Messe München . The first exhibition took place in 1954 as part of the “ Baumusterschau ” at Theresienhöhe in Munich and was then known as the spring show for construction machinery. 58 exhibitors presented their products on

330-626: The George Hotel Aveling-Barford were best known for their line of three-point roadrollers including the small GA up to the GC, The "Master Pavior" 3-point roller was one of the most famous diesel rollers. However many other types of earthmoving machinery were designed and manufactured by Aveling Barford in England. A-B were also significant for their all wheel driven and all wheel steering motor graders often using Leyland Trucks running gear as were also producers of ADT models called

360-579: The RDX Series with 6X6. A line of rigid dumpers was manufactured from 30 tonne RD030 through to the 50 tonne RD050 and eventually a RD55 and RD65 were added. A new dumptruck the RD44 was unveiled at Bauma to try and rejuvenate the line of dumptrucks but with limited success During the 1970s to the 1980s A-B were producing their own range of front loaders with 4X4 axles and are fitted with Cummins , Leyland or Ford heavy duty diesel engines. They resembled

390-797: The Supply of parts to Shellplant. In 2006 Singapore-based ST Kinetics bought the rights to the Aveling Barford RXD series articulated dumptrucks, which are now sold under the TRX Build brand. In August 2007 Moxy Engineering of Norway announced plans to buy the intellectual property rights of the Barford rigid dump truck range. In 2008 Moxy was purchased by the South Korean Doosan (formerly Daewoo), and renamed to Doosan Moxy As and later Doosan Infracore Norway AS. The project

420-522: The collapse of their parent. Edward Barford of Barford & Perkins also chairman of Aveling & Porter enlisted the help of R. A. Lister & Co and its associate Ruston & Hornsby . Lister and Ruston bought the two companies from the receiver. The products of all four businesses were fitted with diesel engines. Aveling & Porter immediately took over the activities of Barford & Perkins changing its own name to Aveling-Barford on 13 February 1934. Early in 1934 operations moved from Rochester to

450-525: The construction equipment company Acrow had wanted to take over Barfords Conservative prime minister Alec Douglas-Home visited Grantham on Friday 29 November 1963, where he stayed overnight in Leadenham , at the home of Lt-Col William Reeve, the chairman of the local Conservative group. The prime minister toured the factory from 1pm, with Edward Barford and went for a day of pheasant shooting at Scopwick , and to Leadenham Hall ; he had dinner at 6pm in

480-411: The effectiveness of a roller depends to a large extent on its weight, self-powered vehicles replaced horse-drawn rollers from the mid-19th century. The first such vehicles were steam rollers . Single-cylinder steam rollers were generally used for base compaction and run with high engine revs with low gearing to promote bounce and vibration from the crankshaft through to the rolls in much the same way as

510-585: The fair was relocated for the first time. In 1962, bauma opened its doors on a former airport site in Oberwiesenfeld, offering 100,000 m more space for—in the meantime—more than 450 exhibitors. But the days of the new location were already numbered: the Olympic Park was created on this site as the 1972 Olympic Games had been awarded to Munich. In 1967, the annual bauma therefore returned to Theresienhöhe, where it remained for decades. In 1967, bauma

540-703: The fair. The trade fair basically comprises four sectors. The "All around construction sites" sector includes suppliers of construction vehicles, construction machinery, construction tools, lifting appliances, formwork and scaffoldings. The exhibition sector "Mining, extraction and processing of raw materials" pools manufacturers of machines for the extraction of raw materials and mining as well as of mineral processing technology. The "Production of building materials" sector comprises machines and plants for producing concrete, asphalt, clay and similar building materials. Drive technology, testing, measurement and control technology as well as accessories including services are presented in

570-413: The flexibility of the tyres provides a kneading action that seals the surface and with some vertical movement of the wheels, enables the roller to operate effectively on uneven ground. Once the soil base is flat the pad drum compactor is no longer used on the road surface. The next course (road base) is compacted using a smooth single drum, smooth tandem roller, or pneumatic tyre roller in combination with

600-511: The hot tar and chip laying machines. Some road companies in the US used steamrollers through the 1950s. In the UK some remained in service until the early 1970s. As internal combustion engines improved during the 20th century, kerosene -, gasoline - (petrol), and diesel -powered rollers gradually replaced their steam -powered counterparts. The first internal-combustion powered road rollers were similar to

630-517: The name Aveling & Porter . Though Aveling & Porter's operations remained independent in 1919 its shares were sold to a new holding company, Agricultural & General Engineers (AGE). The holding company was unsuccessful and collapsed in 1932. Its fourteen subsidiaries – which in the mid-1920s had 10,000 employees – were sold by AGE's liquidator and most of them regained their independence. Two subsidiaries, Aveling & Porter and Barford & Perkins , kept on operating profitably throughout

660-416: The popular British made Bray or Ford loader models of the 1980s. Site dumpers were first mass manufactured by A-B in the 1940s mostly with Fordson Tractor Diesel engines. Today these are still made and sold under the Barford name. The site was bought by Wordsworth Holdings in 1988, who went into administration in 2010. Barfords is now owned by Invictas Engineering. 12 October 2015 Invictas Engineering sold

690-467: The powerful pushing force to spread bulk material. On regional roads, a smaller single padfoot drum machine may be used. The next machine is usually a single smooth drum compactor that compacts the high spots down until the soil is smooth. This is usually done in combination with a motor grader to obtain a level surface. Sometimes at this stage a pneumatic tyre roller is used. These rollers feature two rows (front and back) of pneumatic tyres that overlap, and

720-795: The road rollers in Britain, and world leaders in their field. Edward Barford (23 April 1898 – 11 July 1979) became the chairman of the company from 1933, remaining until 1968. It began making its first earth moving equipment – the Aveling Dumper. During the Second World War the company made Bren Gun Carriers , shell fuse caps and the Loyd Carrier . The company also made calfdozers (small bulldozers ). From April 1946 two subsidiary companies were formed – Barford Developments Ltd and Barford (Agricultural) Ltd. On 17 September 1946

750-408: The steam rollers they replaced. They used similar mechanisms to transmit power from the engine to the wheels, typically large, exposed spur gears. Some users disliked them in their infancy, as the engines of the era were typically difficult to start, particularly the kerosene-powered ones. Virtually all road rollers in use today use diesel power. Road rollers use the weight of the vehicle to compress

780-436: The surface being rolled (static) or use mechanical advantage (vibrating). Initial compaction of the substrate on a road project is done using a padfoot or "sheep's foot" drum roller, which achieves higher compaction density due to the pads having less surface area. On large freeways, a four-wheel compactor with padfoot drum and a blade, such as a Caterpillar 815/825 series machine, would be used due to its high weight, speed, and

810-534: The trade fair company moved from Theresienhöhe to Munich-Riem. Since then, bauma has also taken place there. In 2002, bauma CHINA was launched as first foreign trade fair within the bauma network. In the meantime, bauma CHINA has become the largest capital goods fair in Asia and the second largest construction machinery fair in the world. And meanwhile there is a whole network of bauma trade fairs, including bauma CONEXPO INDIA, bauma CONEXPO AFRICA, bauma CTT RUSSIA and M&T EXPO. In terms of exhibition space, Bauma

840-540: The vehicles were powered by R & H diesel engines. R & H had also previously made road rollers, but concentrated this all at Grantham. Aveling-Barford was listed on the London Stock Exchange in July 1937. In the 1930s it made cooling equipment for dairy farms, and cooking equipment for hotels, hospitals, and canteens . It became a public company on 29 June 1937. At this time it claimed to make 75% of

870-771: Was later cancelled and the prototype of the new range earlier presented at Bauma in 2007 was scrapped. Barfords' sports field is still in existence, called Arnoldfield, in Gonerby Hill Foot. In October 2012 Gravity FM , Grantham's community radio station produced a tribute in words and music to Aveling Barford, on sale to raise funds to support the running costs of the station. [REDACTED] Media related to Aveling-Barford at Wikimedia Commons Road roller Road rollers are frequently referred to as steamrollers , regardless of their method of propulsion. The first road rollers were horse-drawn , and were probably borrowed farm implements (see Roller ) . Since

900-474: Was transferred from private ownership to Messe München's portfolio, and in 1969, the first bauma was organized under the leadership of Messe München. Although successful right from the start, bauma then experienced an incomparable upswing: the award of the Olympic Games turned Munich into the largest construction site in Europe and brought the construction industry an unprecedented order situation. In 1998,
