Hydro Mobile has issued a “Technical Notice” involving bearing bridge application with their equipment. There have been at least two cases where the steel cords on the bottom of the bridge sections in the link plate attachment were damaged beyond repair. This damage was caused by rust, due to inadequate inspections, maintenance and storage, that lead to failure of the bridge section. It is the owners’ ‘duty of care’ to inspect these cords. Frequent (3 month) and annual inspections (ANSI A92.9 and OSHA 1926.451(f)(3) and (4)) must be done by a ‘qualified’ person. These inspections must also have written records that are kept for 4 years. Hydro Mobile is requiring all bridges 10 years or older be immediately inspected.
Hydro Mobile has developed the following 3-point inspection to address concerns of the bridge section.
