The Safe-Away® Variable Height Stair (VHS) has been designed to improve safety and access for operational and maintenance personnel working on drill rigs. Due to the height variations in drill rig positioning, the stair treads will automatically compensate for stair angles between 29° & 45° to the horizontal.

The stair operation is electro-hydraulically controlled. When the drill rig is operational or mobile the Model VHS is retracted to the horizontal position. The Variable Height Stair offers easier access for maintenance personnel when accessing the vehicle and while carrying tools.
