• Bridge Cable Stay Recoating

CAN was requested to undertake bridge cable stay recoating of the Queen Elizabeth II bridge on the M25 at Dartford, Kent.

Works included preparation and reapplication of Metalcoat to the bridge’s main stay cables. All works were carried out above live traffic with minimal traffic management and no disruption to bridge users.

  • CAN designed and constructed lightweight cradles to perform the bridge cable stay recoating, based on its lightweight access platform we chose CAN-Span. These were used in conjunction with rope access methods to provide a stable platform for the coating teams and the client’s independent paint inspectors.
  • The cradles also provided a containment system to prevent spillage of Metalcoat onto the road deck below.
  • Rope access techniques were used to gain access to the cables, which are 220 metres in length and over 80 metres above the road deck.
  • The cradles were installed on each stay cable, winched to the top and lowered down as Metalcoat was applied.
  • The project was undertaken and completed under single lane closures during night time hours, with minimal interference to third party contractors and the general public.
