Additionally during set-up, operation and retrieval phases road traffic disruption is kept to a minimum.
This highly mobile unit (UBI 3) has a reach of 13 metres underneath a bridge and a downward access of 16 metres. It can easily reach over side walks with its extension, making it ideal for those hard to reach spots of a bridge. The basket is able to raise up an additional 2 metres allowing for perfect access to inspect bearings. Because this unit is so versatile it is perfect for steel truss bridges that need inspection.
