Roll-off (dumpster)
In North America, a roll-off is a usually open top dumpster characterized by a rectangular footprint, utilizing wheels to facilitate rolling the dumpster in place. The container is designed to be transported by special roll-off trucks. There are two types of delivery trucks for the bins based on bin size and they are: Hook lift bins and Roll-off bins. Roll-offs are commonly used to contain loads of construction and demolition waste or other waste types. While most roll-off containers have a swinging door on the end for easier disposal of waste, some roll-off containers are not open top and are used with commercial or industrial trash compactors. Construction debris may originate from a building site where something is being built, renovated, or demolished. Roll-off dumpsters are also used for various jobs that need much material to be taken away. The material in the roll-off may be taken to a landfill, recycled or disposed/recovered of in some other way. Size Roll-off contai ...

Roll-Off
Roll-off is the steepness of a Transfer function, transfer function with frequency, particularly in network analysis (electrical circuits), electrical network analysis, and most especially in connection with filter (signal processing), filter circuits in the transition between a passband and a stopband. It is most typically applied to the insertion loss of the network, but can, in principle, be applied to any relevant function of frequency, and any technology, not just electronics. It is usual to measure roll-off as a function of logarithmic scale, logarithmic frequency; consequently, the units of roll-off are either decibels per decade (log scale), decade (dB/decade), where a decade is a tenfold increase in frequency, or decibels per octave (electronics), octave (dB/8ve), where an octave is a twofold increase in frequency. The concept of roll-off stems from the fact that in many networks roll-off tends towards a constant gradient at frequencies well away from the cut-off freque ...

Municipality
A municipality is usually a single administrative division having corporate status and powers of self-government or jurisdiction as granted by national and regional laws to which it is subordinate. The term ''municipality'' may also mean the governing body of a given municipality. A municipality is a general-purpose administrative subdivision, as opposed to a special-purpose district. The term is derived from French and Latin . The English word ''municipality'' derives from the Latin social contract (derived from a word meaning "duty holders"), referring to the Latin communities that supplied Rome with troops in exchange for their own incorporation into the Roman state (granting Roman citizenship to the inhabitants) while permitting the communities to retain their own local governments (a limited autonomy). A municipality can be any political jurisdiction, from a sovereign state such as the Principality of Monaco, to a small village such as West Hampton Dunes, New York. Th ...

Demountable Rack Offload And Pickup System
The Demountable Rack Offload and Pickup System (DROPS) is a family of logistics vehicles operated by the British Army, which consists of two vehicle types: * Leyland DAF medium mobility load carrier (MMLC) * Edwin Foden, Sons & Co., Foden improved medium mobility load carrier (IMMLC) Both are able to transport 15-tonne flatracks or containers configured to ISO 20 feet standard and to load and offload them autonomously. Both may be supported with side rail transfer equipment (SRTE) for loading and unloading railway wagons. The DROP system was designed to meet the very high intensity battles in Central Europe in the last decade of the Cold War. However it entered service after the collapse of the Warsaw Pact but nevertheless proved a versatile vehicle system on operations completely different from those originally envisaged. Operational requirement The DROP system developed from the revaluation of readiness and firepower requirements of British Army of the Rhine (BAOR) in the mid-1 ...

Waste Management
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, economic mechanisms. Waste can be solid, liquid, or gases and each type has different methods of disposal and management. Waste management deals with all types of waste, including industrial, biological, household, municipal, organic, biomedical, radioactive wastes. In some cases, waste can pose a threat to human health. Health issues are associated throughout the entire process of waste management. Health issues can also arise indirectly or directly. Directly, through the handling of solid waste, and indirectly through the consumption of water, soil and food. Waste is produced by human activity, for example, the extraction and processing of raw materi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waste Container
A waste container, also known as a dustbin, garbage can, and trash can is a type of container that is usually made out of metal or plastic. The words "rubbish", "basket" and "bin" are more common in British English usage; "trash" and "can" are more common in American English usage. "Garbage" may refer to food waste specifically (when distinguished from "trash") or to municipal solid waste in general. Designs A pedal bin is a container with a lid operated by a foot pedal. Lillian Moller Gilbreth, an industrial engineer and efficiency expert, invented the pedal bin in the 1920s for the disposal of kitchen waste. The foot pedal enables the user to open the lid without touching it with their hands. In the 2010s, some bins have begun to include automated mechanisms such as a lid with infrared detection on the top of the can powered by batteries to open it rather than a foot pedal, freeing the user from touching the bin in any way. This helps prevent the bin lids becoming clogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank Chassis
Container chassis, also called intermodal chassis or skeletal trailer, is a type of semi-trailer designed to securely carry an intermodal container. Chassis are used by truckers to deliver containers between ports, railyards, container depots, and shipper facilities. This type of trucking is sometimes called drayage. Operation A container is lifted onto a chassis by a specialized crane, ensuring that the container's corner castings line up with the chassis’ twistlocks (pins). The container is locked to the chassis by engaging the pins. The length of a chassis determines which container length it can accept. For example, a 40-foot-long chassis is used for a 40-foot-long container. Some chassis can be extended or shortened depending on which container needs to be hauled. Chassis have a kingpin so they can be connected to a semi-tractor. They also have a pair of legs called landing gear that can be cranked down to park them when not hooked up to a tractor.

Skip (container)
A skip (or skip bin) is a large open-topped waste container designed for loading onto a special type of lorry. Typically skip bins have a distinctive shape: the longitudinal cross-section of the skip bin is either a trapezium or two stacked trapezia. The lower trapezium has the smaller edge at the bottom of the skip bin, and a longer edge at the top. The smaller edge on either end is lower which makes it easier to load. Where there is an upper trapezium, it has the smaller edge at the top. There is a sloping floor or wall at each end. There are usually two lugs on each side of the bin onto which chains can be attached, permitting the heavy skip bin to be lifted onto and off a skip lorry or skip truck. A special skip-carrying lorry or crane is used. One end of the skip sometimes has a large door that hinges down to allow manual loading and unloading, these skips are called 'drop-door skips'. Skips are usually durable and tough, made to withstand rough use by tradespeople and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sidelifter
A sidelifter is a specialised vehicle or semi-trailer used to hoist and transport ISO standard intermodal containers over longer distances. Overview The sidelifter loads and unloads containers via a pair of hydraulic powered cranes mounted at each end of the vehicle chassis. The cranes are designed to lift containers from the ground, from other vehicles including rolling stock, from railway wagons and directly from stacks on docks or aboard container ships. A standard sidelifter is also able to stack a container at a two containers' height on the ground. If the sidelifter chassis is of 40' length or more, the cranes of the sidelifter can be shifted hydraulically along the sidelifter chassis to be able to pick up either one 20', one 40', or two 20' ISO containers at a time. As the Sidelifter is suitable for travelling on general roads for large distances and able to quickly load and unload without additional equipment, it is often used for delivering and picking up shipping contai ...

Roller Container
A roller container is a container type that can be carried by trucks to be pushed to ground level by help of a hook and level arm with the container possibly sliding on steel roller wheels. Its original usage was in the collection of bulk waste resulting in the creation of the DIN standards to be initiated by city cleaning companies. An additional part defines a transport frame mounted on specialized rail cars that allows easy intermodal transport for these container types. Another important area is in the containerization of firefighting equipment used as swap body containers of fire trucks. Etymology The term "roller container" has been introduced in the English summary of the DIN standards that refer to the prominent feature of steel wheels - such wide wheels are commonly known in English as rollers. It does also refer to the verb "to roll" which has the same meaning in German - the particle "ab-" in German "abroll container" designates downward/pushback operations so that ...

Dumpster
A dumpster is a movable waste container designed to be brought and taken away by a special collection vehicle, or to a bin that a specially designed garbage truck lifts, empties into its hopper, and lowers, on the spot. The word is a generic trademark of ''Dumpster'', an American brand name for a specific design. Generic usage of ''skip'' or ''skip bin'' is common in the UK, Australia and Ireland, as Dumpster is neither an established nor well-known brand in those countries. History The word "dumpster", first used commercially in 1936, came from the Dempster-Dumpster system of mechanically loading the contents of standardized containers onto garbage trucks, which was patented by Dempster Brothers in 1935. The containers were called ''Dumpsters'', a blending of the company's name with the word '' dump''. The Dempster Dumpmaster, which became the first successful front-loading garbage truck that used this system, popularized the word. The word ''dumpster'' has had at least three ...

Private Property
Private property is a legal designation for the ownership of property by non-governmental legal entities. Private property is distinguishable from public property and personal property, which is owned by a state entity, and from collective or cooperative property, which is owned by a group of non-governmental entities. Private property is foundational to capitalism, an economic system based on the private ownership of the means of production and their operation for profit. The distinction between private and personal property varies depending on political philosophy, with socialist perspectives making a hard distinction between the two. As a legal concept, private property is defined and enforced by a country's political system. History Ideas about and discussion of private property date back to the Persian Empire, and emerge in the Western tradition at least as far back as Plato. Prior to the 18th century, English speakers generally used the word "property" in reference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
License
A license (or licence) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit). A license is granted by a party (licensor) to another party (licensee) as an element of an agreement between those parties. In the case of a license issued by a government, the license is obtained by applying for it. In the case of a private party, it is by a specific agreement, usually in writing (such as a lease or other contract). The simplest definition is "A license is a promise not to sue," because a license usually either permits the licensed party to engage in an activity which is illegal, and subject to prosecution, without the license (e.g. fishing, driving an automobile, or operating a broadcast radio or television station), or it permits the licensed party to do something that would violate the rights of the licensing party (e.g. make copies of a copyrighted work), which, without the license, the licensed party could be ...
