Field Repairs

Field repairs are very unique jobs that take experience and ingenuity. Many bridges and especially movable bridges consist of very large pieces of machinery like hydraulic cylinders. With the importance and effort to maintain traffic flow, combined with the obstacles of new technologies outdating old ones, making repairs at this time has many obstacles and usually includes: special rigging, precision machine work, hydraulic powered rigs, tools specially fabricated, and innovation throughout a team of specialist.
