Intervention Techniques

The Landings

Landing is by far the most secure way when participating in a rescue mission. During the first assistance to the injured, the helicopter can be turned off and the transport of the casualty can be done in complete safety and tranquility. This results in a reduced tension of the turbines in function. Crampons integrated onto ice-skates are used in extreme winter conditions such as snow & ice. Helicopter landings with the
H 135 T3 are possible on a max. 14 degrees slope.

The Hovering (Hovering)

Hovering (stationary flying) is the best solution when intervening in rescue missions and fast recovery is necessary and it is impossible to land. The main rotor can in fact turn in proximity of land and constitute therefore a danger especially to staff intervening in the rescue. Therefore we use the winch to hoist the casualty for a short distance and guarantee that the main rotor is not near an obstacle.

Rescue with Winch

Despite this relatively small device, the winch is of high importance. The Doctor is lowered by the winch where the helicopter cannot land or hover to pick up the injured and take them to medical aid in the shortest possible time.

A large number of the recoveries are carried out with this winch up to a max. 270kg and 90m cable release.

Only in extreme cases where the steel cable of the winch could hit against the vertical cliffs and the maximum length is not enough, then the fix rope hooked on to the double hoist hook, is used. The winch has approx. 90 m of cable with a max hoist weight of 230 kg.

The casualty, doctor or rescue crew, are winched into the helicopter cabin.

The casualty is turned for the crew to load into the cabin. The casualty is turned for the crew to load into the cabin.

The casualty is securely anchored into the cabin and the crew members fasten their safety belts. The casualty is securely anchored into the cabin and the crew members fasten their safety belts.

Fix rope rescue system

The double hoist hook, conceived and legally licensed for human cargo, allows a maximum weight of 600 kilograms. The long-line fix rope theoretically does not have a maximum length limit. We have had to intervene twice with a 120 m rope in the Dolomite Mountains but normally we use 100 m rope. The advantage of the double hoist hook which is fixed to the cargo centre of the helicopter, allows the possibility of fast evacuation of up to 4 persons at a time. Furthermore, the winch can be used in numerous occasions, as it allows us to save time and reduce danger, ie. evacuate cable cars and lifts.
