Method of protecting a roadway maintenance and construction site

摘要

A method of protecting a roadway maintenance or construction site in which a crash cushion is suspended beneath a straddle carrier-type vehicle. The crash cushion preferably comprises an inertial system of free standing sand filled plastic containers or other suitable impact attenuator which in some cases is used with a backup structure. The vehicle is connected to a towing vehicle and is towed to the maintenance or construction site or can also be used in a self-propelled configuration. When the crash cushion is located in a position to block oncoming traffic at the site, it is lowered onto the roadway and disconnected from the straddle carrier-type vehicle. The towing vehicle and straddle carrier-type vehicle can then be removed from the site leaving the crash cushion in a fixed and favorable position relative to oncoming traffic.
