Mattresses and Accessories - Drive, Delta Ultra Light Semi Electric Hospital Bed with Half Rails : This lightweight, interchangeable and easily assembled semi-electric bed (with half side rails) is the ultra-light plus model from Drive Medical. Its new universal style head and foot boards are interchangeable, featuring high impact composite end panels. The foot section weighs 50 percent less than conventional foot sections, making your deliveries safer and easier. Bed assembly requires only five components. Even motor assembly can be either installed or removed tool free with the patient still in the bed. The unique single motor and junction box are self-contained to reduce noise and prevent disruptions or distractions. Even in the event of a power failure, a 9-volt battery, located in the motor, can lower the head and foot sections up to nine times, no crank necessary. A new-and-improved hand pendant includes large, easy-to-use controls, and this bed kid includes half side rails for additional safety. The bed features channel frame construction with zinc coated spring deck to provide superior strength and reduced weight.
