Jersey barriers have been used extensively in the American occupation of Iraq to fortify road-blocks and public infrastructure, along with modern "T" and "L" barriers, much taller variants. The current shape was first implemented in 1959 as a result not of crash testing, but of police observation of the accident results of previously installed concrete barriers. New Jersey first used concrete traffic barriers in 1955. The older guard rail barrier system did not prevent traffic from entering oncoming traffic. Residents, government agencies, and road traffic and media reports on radio and television (including stations located in New York City and Philadelphia) usually use the term "traffic divider". In the State of New Jersey the term "Jersey barrier" is rarely used. Concrete safety shape barriers should be adjacent to a paved surface so that the wheels cannot dig into the soil and cause the vehicle to overturn. If the vehicle is lifted too high into the air, it may yaw, pitch, or roll, which can cause the vehicle to roll over when the wheels come in contact with the ground again. This aids in banking and redirecting the vehicle.
It is only necessary to lift the vehicle enough to reduce the friction between the tires and the paved surface. Modern vehicles have relatively short distances between the bumper and the wheel as a result, bumper contact is followed almost immediately by wheel contact. Therefore, exposed aggregate and other rough surface finishes should be avoided. However, wheel side-scrubbing forces provide some additional lift, particularly if the barrier face is rough. Most of the additional lift of the vehicle is caused by the lower sloped face compressing the front suspension. Then, as the vehicle becomes more nearly parallel with the barrier, the wheel contacts the lower sloped face. If the bumper is relatively weak, the front end starts to crush before any uplift occurs. This interaction initiates lifting of the vehicle. The front bumper impacts the upper sloped face and slides upwards. The design of the Jersey barrier was specifically intended to minimise damage and reduce the likelihood of a car crossing into oncoming lanes in the event of a collision For the more common shallow angle hits, the Jersey barrier is intended to minimise sheet metal damage by allowing the vehicle tires to ride up on the lower sloped face.įor higher impact angles, the Jersey barrier is actually a multistage barrier. Jersey barriers are concrete barriers originally developed for highway medians. Each SWIFT LIFT component is rated to 5 tonne. By attaching the SWIFT LIFTS to your crane you can manoeuvre the barriers into place and from place to place. The component you'll need for rigging your crane to the barrier is called a SWIFT LIFT. They are also known as temporary concrete traffic barriers orīelow is an image of the component used in the tops of our Jersey barriers. Their widespread use on the highway has led to many other uses as a general barrier (for instance, during general construction projects or constructing temporary walkways). A Jersey barrier stands 3 feet tall and is made of poured concrete. (under the direction of the New Jersey State Highway Department) to divide multiple lanes on a highway by the state of New Jersey in the United States.
The Jersey barrier was originally developed at Stevens Institute of Technology in Hoboken, N.J. If you need the impressions to be a different size or width apart then you will need to tell us when you are making the order. If you specifically ask us for impressions for use with forklifts then by default the impressions will be made at 900mm apart (to the centre of the impressions) and each impression is 170mm wide x 60 mm high. They have also come into use as a means to keep car bombs away from perceived targets.
A Jersey barrier or Jersey wall separates lanes of traffic (often opposing lanes of traffic) with a goal of minimising vehicle crossover in the case of accidents. Not all forklifts have the same tyne dimensions and tyne spread so we would need to custom suit the dimensions and spread to suit your forklift. If you need impressions in the bottom to be able to move the barrier yourself with a forklift then you need to advise us when ordering.
