Barrier Transfer machines, also known as Zipper Machines, are heavy vehicles used to transfer Jersey barriers or other concrete lane dividers to relieve traffic congestion during rush hours. A Jersey barrier was originally developed to divide multiple lanes on a highway by the state of New Jersey in the United States. ...
The vehicle contains an S-shaped channel in its undercarriage which lifts 5-foot long, 500 pound barriers just off the road surface and slides them over to the other side of the lane, reallocating traffic lanes to accommodate increased traffic. These barriers are linked together with steel connectors to create a formidable but flexible safety barrier.
Moveable barriers are in permanent use in such cities as Philadelphia, New York City, Boston and Dallas, while many other cities use them temporarily during construction work. Philadelphia is a village located in Jefferson County, New York. ...
