The NoRo Hoist is a conversion of a normal rescue hoist into a twin-rope pul- ley system. The benefits of the hoist remain and the major problems are eliminated, vastly increasing the safety and efficiency of hoist operations. A successful synthesis between proven twin rope system tech- nologies and innovative ideas creates un- matched opportunities for hoist operations. With a hook-damper unit, wiring and a spooler unit including a secondary rope and emergency release, ecms Aviation Systems will turn your hoist into a NoRo Hoist. Here’s how it works:

Pros and Cons of the NoRo Hoist:

PROs:

• Double payload for mass evacuation • Rotational stability – no ground- based anti-rotation lines required

• Very small center of gravity offset • Lateral pendulum stability – heli- copter handling is greatly simplified

• Choice between normal hoist and NoRo operation at any time

CONs:

• More weight through additional components

• Double payload cannot reach cabin level

• Reduced rope range • Reduced hoisting speed ❚

ecms Aviation systems is an EASA- approved design and production organization for helicopter equipment. ecms was founded in 1999 by Matthias Schuster shortly after his aeronautical engineering studies during which he noticed a lack of quality equipment on the market in this specific field. Safety was the key that started the company and continues to be the number one priority. Today, ecms is specialized and market leader in human external cargo systems for rescue and aerial work applications, fast roping and rappelling provisions for police and military helicopters, cargo hook weighing systems and other mission equipment and helicopter modifications.
