Track Mounted Folding Stairs

The Track mounted folding stairs version of FlowStep incorporates our popular folding stair and cage system into a modular sliding rail which features a track mounted gangway

The Track Mounted Folding Stairs system comes with gantry-mounted lockable swing gates installed at intervals in the railings, therefore allowing tanker access no matter where the tanker is positioned. So, the entire cage and stairs can be moved by hand with very little effort and runs smoothly on heavy-duty bearings. Once in position, a locking bolt is set by the operator, preventing the system from sliding when in use. In addition, the stairs operate as usual, allowing easy access to tankers of varying heights.
