1.3.2 CONSTRUCTION
Howard Wright Limited products are manufactured from high quality durable engineering materials including steel,
aluminium and stainless steel with a durable epoxy/polyester hybrid powder coated finish. High quality durable
engineering plastics including Nylon, ABS, TPR & Polypropylene are also used.
M9 stretchers have a LINAK control box. This uses mains power at 220-240 V AC (50-60 Hz) to operate LINAK
actuators at 24 V DC. An on-board sealed lead-acid battery provides power when mains power is not available (e.g.
when moving the stretcher). Control buttons are located on a remote handset for adjustment of the backrest, deck
height, deck tilt, legraise and an auto-contouring preset function.
