Just like other pieces of infrastructure, bridges also suffer wear, and must be inspected regularly. The importance of regular inspection and maintenance of bridges cannot be over-emphasized. In case of failure, the consequences are often catastrophic.
However, the conventional methods of bridge inspection rely of images taken from below (which usually do not offer enough details) or trucks equipped with special booms that place people under the bridge, but often disrupting the traffic. Bridge-View was developed to finally bring Bridge Inspection to the 21st century.
It consists of an inspection device that is hanging from 4 tethers. By controlling the length and tension of all tethers, the inspection device can be moved and covers the bottom surface of the bridge. Since the inspection device is close to the bottom surface, it can acquire images and data from other sensors with a high degree of detail and repeatability.
In addition, an expandable arm in the inspection device allows it to place the sensors in places that have been inaccessible so far, such as inside truss structures, or in the narrow spaces between the bridge and the pylons. Data collected from these narrow spaces can often bring important information about the health of the bridge, and allows asset managers to estimate the life of the structure and the need for maintenance with an unprecedented level of reliability.
The tethers are controlled by four smart winches, assembled on the top of the bridge and placed along the guard-rails. The smart winches are all connected to each other, take little space, and do not disturb the traffic of people or vehicles on the bridge.
Bridge-View sets the standard for inspection and maintenance of bridges in the 21st century: smart, efficient, detailed and unobstructive.
