A&H has four product lines. HESLO is helicopter external sling load equipment. HEC is human external cargo equipment. MIL covers military equipment. Intervention covers equipment for rescue and intervention work.

The company offers engineering, equipment, services, expert advice and documentation. Engineering covers development, certification and documentation. Equipment covers load lifting devices and slinging equipment, made in Immensee, with a few steel and plastic parts made by subcontractors.

A&H Engineering develops products and then qualifies or certifies them. It qualifies load lifting devices and slinging equipment for helicopters and drones.

The workshop also does electrical work on aviation connectors. The site gives a split of 90 percent crimping, 2 percent soldering and 8 percent screwing for about a dozen connector types. The company publishes its events, and the next one is ERFA Flughelfer on November 13, 2026. The site also has a library and press page, and a sustainable development goals page.
