To facilitate moving rolls on and off the air-shaft body per OSHA-recommended upper limit of forces for horizontal pushing and pulling, co. has designed ergonomic surface rollers. The surface rollers are a fixed-height assembly of low-friction wheels that minimize the initial force and sustained force when moving a roll onto a cantilevered air shaft. They are designed to slide into one or more of the existing slots in co.'s external bladder models.
