Wall-climbing Robot for Maintenance of Bridge Tower

I&T Wish Wall-climbing Robot for Maintenance of Bridge Tower
(REF: W-0532)
Matched I&T Solution
Trial Project
Summary and Challenges
  • The Shenzhen Tower of Shenzhen Bay Bridge is about 140m tall. Cleansing and repair works for the external tower wall including re-painting, removal of stain and rust are required for routine maintenance works.  These works are currently being carried out by workers on the mobile crane. Lane closure with temporary traffic arrangement is required for the operation, which will affect the public usage of Shenzhen Bay Bridge.
  • We hope to explore the use of wall-climbing robot to carry out the routine inspection, cleansing and repair work for the external wall surface of Shenzhen Bay Bridge Tower. The wall-climbing robot should be able to be operated automatically or manually with a remote controller. The robot should map the inspection route and record location and details of identified areas of inspection.
  • The robot should be able to carry out repair works using methods such as water jetting, polishing and painting on the bridge tower wall.
  • The robot should be able to operate under windy condition (wind speed up to 30km/hr in 10 minutes-mean) on the painted concrete wall surface.
  • The robot should be equipped with safety devices / provisions to prevent the robot and its accessories, if any, from falling from the working location to the bridge carriageway creating safety hazard to the public.
  • The working space at the Bridge tower base for robot operation is approximately 5m wide x 20m long on floor plan.
Expected Outcome
  • We expect the wall-climbing robot can provide a safe and efficient way for the maintenance of bridge tower, not only reduce the risk of fall from height, but also reduce the nuisance to the public caused by lane closure.
Expected Trial Duration 6-month
