SEGMENT MOVED FORWARD

When the supports are ready, the Iron Monster moves forward to the front of the bridge, bringing the next approximat­ely 50-m-long and 7-8m-wide concrete bridge segment.

SUPPORT LEGS ATTACHED

The Iron Monster lowers two support legs onto the edges of the bridge supports. In this position, the device can move towards the next support without the risk of overturnin­g.

MONSTER ADVANCES

Then the monster moves to the next support, where the front support legs are attached. When the back support legs have been raised, the next segment slides forward.

SEGMENT POSITIONED

When the bridge segment has been advanced, it is lowered onto the two supports, and the support legs move on to the next support, so the process can be repeated.
