The staircase is assembled on a towable steel closed profile chassis. The steps and the upper platform are covered with aluminium antiskid sheet.

Manually operated stabilizers secure the stability of the stair when it is in the operational position.
Stair Raise
The raising of the stair is achieved by a hydraulic cylinder with an independent hydraulic system, powered by a hand pump. The uplift can be adjusted within the aforementioned height range. The stair is locked at the desired height level by a safety mechanism.
