FoLdiNq STAIRS Silea folding stair is realised to facilitate access from cantilever roof to working position on top of tankers. The folding stair is complete of a load bearing fixed tubular structure and metal section bars, designed to withstand persons loads and movements and it is complete of a mobile load bearing structure, also with tubular structure, constrained to the fixed part by means On the mobile part, a series of antiskid grating steps are mounted Th#structure is complete of a safety hands guard rail which follows stair movement, and of a mechanical piston for movements. Every steps is divided in two parts: a fixed one and a mobile one, to avoid accidents in case of wrong feet placement on the step. The number of steps defines the reach and so the stair usage in function of the customer requirements. • difference in height from walking plane: 800 mm • difference in height from walking plane: 1080 mm • difference in height from walking plane: 1370 mm The folding stair is complete of bearings and bush in friction points and there is the possibility of mounting a second piston for a protection case, when needed. The structure is treated with double painting layer: the first by Catapho- resis, the second by powder RAL 7035 colour. Cataphoresis is an electrophoresis treatment with epoxy paintings which has high resistance to corrosion and it is guaranteed until 1000 hours in salty fog. The folding stair complies with applicable Directives and has mark. Reliability and handiness of our product is guaranteed by usage of light and resistant materials, by advanced technologies applications and by more than 20 years experience, acknowledged around the world.
