Skates can be used wherever heavy objects have to be moved. The large diameter nylon rollers ensure easy movement and spread the load evenly, protecting the floor or ground from damages caused by high point loads. A practical steel handle is welded onto the skate for easy and safe handling and positioning of the skates. The platforms of the skates are fitted with a rubber surface which helps grip and protect the object being moved. Powerful wheel pins. The wheels are mounted in rubber-sealed roller bearings (RS). In SF10 and SF20 there are no bearings mounted due small nylon wheels.
