Revopak
The Revopak is a type of waste collection vehicle manufactured by the British company Shelvoke and Drewry. Introduced in 1971, the Revopak was a British-built clone of the French Bennes-Ray "Superpac".{{cn, date=April 2020 It was one of the first vehicles to address the problem of compacting and destroying the high content of packaging materials now found in domestic refuse. By using a huge, hydraulic-powered rotating rake with large steel tines, refuse was scooped up from the loading hopper and forced through a set of stationary tines. The rotation of the rake increases the density of the load by continuously lifting the waste, mutilating it through the stationary tines, and then dropping it and repeating the cycle until it is small enough to be forced into the main body, where it is compacted, thus reducing the space required to dump it at the landfill site. Two generations of the Revopak were produced - the early 1971-1973 models used hydraulic motors which drove the comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shelvoke And Drewry
Shelvoke and Drewry was a Letchworth, Hertfordshire manufacturer of special purpose commercial vehicles. It was best known for its innovative waste collection vehicles that were the preferred choice of municipal authorities in the UK together with their gully emptiers, cesspool cleaning vehicles and street watering and washing vehicles.Shelvoke And Drewry Limited. ''The Times'', Monday, 26 April 1937; pg. 23; Issue 47668 Cable drum carriers were supplied to the General Post Office and vehicles and ground equipment built for the Royal Air Force. Shelvoke and Drewry also manufactured fire engines, buses and fork-lift trucks. The Shelvoke and Drewry Freighter The business began in 1921 as a partnership of Harry Shelvoke and James Drewry, both of whom had successful careers in commercial vehicle design and manufacture. At that time, municipal refuse vehicles were almost all horse-drawn, uneconomical and inconvenient and required the use of ladders. In their "S D Freighter", Shel ...

Waste Collection Vehicle
A garbage truck is a truck specially designed to collect municipal solid waste and transport it to a solid waste treatment facility, such as a landfill, recycling center or transfer station. In Australia they are commonly called rubbish trucks, or garbage trucks, while in the U.K. dustbin lorry or bin lorry is commonly used. Other common names for this type of truck include trash truck in the United States, and refuse truck, dustcart, junk truck, bin wagon or bin van elsewhere. Technical names include waste collection vehicle and refuse collection vehicle (RCV). These trucks are a common sight in most urban areas. History Wagons and other means had been used for centuries to haul away solid waste. Among the first self-propelled garbage trucks were those ordered by Chiswick District Council from the Thornycroft Steam Wagon and Carriage Company in 1897 described as a steam motor tip-car, a new design of body specific for "the collection of dust and house refuse".

Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Landfill
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses. Operations Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: # confine waste to as small an area as ...

Hydraulic Ram
A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water. History The Alhambra, built by Nasrid Sultan Ibn al-Ahmar of Granada beginning AD1238, used a hydram to raise water. Through a first reservoir, filled by a channel from the Darro River, water emptied via a large vertical channel into a second reservoir bene ...
