I bought four ramps for occupancy our basement stairs with two ramps on each side, in order to shut down heavy objects with a hand truck can. The levels are about 90 cm wide, so that the aisle remains about 30 cm free and the aluminum hand truck runs just inside the side edges of the ramps. The staircase is significantly steeper than indicated by the manufacturer difference in height of one meter, ie about 1.40 m each ramp length. Therefore, the ramp elements are scrupulously protected with the supplied straps. The lower lamp elements overlap the top by approximately 50 cm and are connected to the upper ramp fixed with straps. Since the basement stairs consists of quintet aluminum sheet, obtained by the angular profile of the stages and the ramps a remarkable friction effect: The metal surfaces tend to hardly slipping. I've tested this configuration extensively; Here were all the ramp elements are stable. The resilience hardly plays a role, because the ramps at least 60% on the step edges resting. To transfer this configuration on stone steps, one would have to demonstrate the steps previously with soft, sticky rubber sheets. For this purpose, underlay mats for sports equipment, eg. B are in the size 90 x 200, you can crop them accordingly, here takes on Amazon.
