The Integral assist is a swivel castor with central, total or directional lock, specifically engineered for electromobility applications requiring reliable manoeuvrability and stability. This castor features a stem with cam hole for profile bars in short version, enabling seamless integration into medical equipment and mobility solutions. The wheel comprises a 150 mm diameter polyurethane tread, which is casted to provide superior durability and consistent performance across demanding healthcare environments. The steel and iron body construction ensures robust structural integrity and longevity, making it suitable for use in hospitals, nursing and retirement homes, and various medical facilities. The Integral assist is ideally suited for anesthesia carts, medication carts, nursing carts, computer workstations on wheels, dialysis equipment, hospital beds, stretchers, ventilators, and diagnostic imaging systems including C-arms, CT scanners, MRI and X-ray equipment, as well as ultrasound units. Its comprehensive locking mechanism provides enhanced safety and control, whilst the polyurethane wheel material delivers smooth, quiet operation essential for sensitive healthcare settings.
