Barrel construction (formally known as "drum bum" in the United States) is a traffic control tool used to deliver motor vehicle traffic through construction sites or to alert riders of construction activities near the highway. They are used mainly in the United States, but are occasionally used in Canada and Mexico. They are a smaller traffic cone alternative and easily hit by a vehicle. Drums tend to be more respectful to drivers than cones because they are bigger, more visible, and give the impression of being a formidable obstacle.
Construction casks are usually bright orange and have four reflective tones white and orange. But some areas, such as the province of Ontario, Canada, use black lines instead of white. Most have rubber bases that prevent the barrel from falling during high winds or when hit by a vehicle. The barrel construction has a handle on the top so they can be easily taken and carried. The handle also allows the crew to install barricades to increase visibility. This product forms an industry worth $ 90 million in the United States.
Until the late 1980s, the construction crew typically used a 55-gallon steel drum to guide traffic through the construction area. They are painted orange and white and filled with sand or water to keep them in place. Because drums are steel and burdened with sand or water, extensive damage will occur to vehicles that hit them. The plastic casks often seen on American highways today began to appear in the late 1970s and 1980s; 55-gallon steel drums were largely removed in the 1990s and may no longer be used as a means of traffic control in the US.
In 1981, drums were primarily a two-part plastic design that included the top of the drum and the base filled with sandbags. In the same year, the latest version of the invention was released by PSS; it includes flanges to allow the placement of sandbags outside the drum making it easier to maneuver. In 1985, PSS released a modern version of the construction vat, LifeGardÃ,® drums. LifeGardÃ,® utilizes the sidewall of a recycled tire truck at the bottom to keep the drum in place on the highway. This design is the most commonly used today.
