发明名称 Fall protection system for bridge construction
摘要 A fall protection system for bridge construction includes a plurality of generally T-shaped cable supports securable to the concrete support columns of a bridle or overpass during construction. A plurality of cables are coupled between the T-shaped supports which receive a corresponding plurality of slidable safety belt attachments for use in securing a plurality of construction workers wearing appropriate safety harnesses to the overhead cables. Embodiments are shown in which the T-shaped cable supports are secured either to the extending reinforcement bar cages of each concrete support column or, alternatively, received directly within a suitably formed closed end bore within the concrete pier of the support column.
