These Axial Mobile Steps are based on our standard heavy duty range of steps, with all the strength, but with narrow steps and 4 swivel castors. This gives them great manoeuvrability and makes them ideal to go down narrow spaces or aisles where access is tight.On the standard steps, the wheels on the rear axle protrude beyond the steps for stability. These narrow aisle steps have the wheels mounted under the framework of the steps, which means they are suitable for racking with narrow aisles or tight spaces.Note though, that they should not be used in open spaces as they are not as stable if the operative is leaning out. In order to improve stability, all our Axial Mobile Steps have tapering sides so the user is forced to stand over the centre line.Our Axial range sports 4 swivel castors which enable the steps to rotate within their own footprint. These swivel castors can be raised so the steps frame bottoms out on the ground.There are 2 lever brakes which disengage each pair of wheels
