ABSTRACT:
A mobile transfer and transport vehicle is adapted to move a barrier system, having a plurality of pivotally interconnected and closely spaced modules, on a roadway or the like. The vehicle includes a conveyor having series of guide and support rollers for engaging, supporting, lifting and transferring the barrier system from a first side of the vehicle to a second side thereof. A drive system is mounted on the conveyor for frictionally engaging the modules to either pull or retard movement of the modules through the conveyor. The drive system aids in maintaining proper spacing between the modules, particularly when they are moved on a curved roadway.
