Abstract

See full text

A crowd control barrier system is formed by regular barrier units interlocked end to end, with special wheeled units at intervals which provide elevated platforms for crowd surveillance. The special units can be converted to provide mobile storage racks for the regular units, which mobile racks can be wheeled onto a trailer or other vehicle for transportation and storage. The regular barrier units are formed of two continuous tubular members, one forming a frame for a vertical panel and one side of a base frame, and the other forming the other side of the base frame and vertical members welded to vertical portions of the first member to form vertical stanchions supporting the panel.
