The HMS01 is our innovative twin-rope external load system for the BK-117 and the Bo-105. The system consists of a skid-mounted lever assembly which retracts automatically for takeoff and landing, various load attachment devices or cages and an electronic control box. The device is self-monitoring and incldues a redundant pyroelectric emergency release system.

With only a minimum of fixed provisions, required, the mechanical parts of the AirAccess system can be installed in just a few minutes without requiring any tools.

The foremost feature of the patented AirAccess system is the usage of two parallel ropes instead of a single rope. Thus, the dangerous turning tendencies sometimes encountered during fixed rope or hoist operations are effectively eliminated, and no anti-rotation line operator is needed. A passive dampening system additionally reduces pendulum instabilities of the load.

The AirAccess system supports loads (NHEC and HEC) of up to 500kg and thus allows for mass evacuation operations for at least 5 persons simultaneously. AirAccess includes an internal weighing system as a standard. Various readout possibilites are available as optional equipment.

Additional equipment (harnesses, slings, rescue stretcher, connectors etc.) usable with the HMS01 is included in the certified HRS01 package
