Tilly (also Tilley or Tillie , probably from utility ) is the slang term for crane vehicles on US flight deck ships. Common names are Aircraft Crash Handling and Salvage Crane , Flight Deck Crash Crane or Shipboard Crash Crane . The vehicle is an important and indispensable part of the rescue and accident teams.

The crane is used to remove crashed or damaged aircraft from the runway as quickly as possible, even in difficult weather conditions and ship movement. In addition, the crane is used for moving heavy loads, e.g. B. in the maintenance of aircraft used. If the Tilly is not operational, all flight operations on the flight deck will be suspended until it is repaired.

There are currently two types of this type of crane on board American warships, the A / S 32A-35 Aircraft Carrier Crash Crane (CVCC, for aircraft carriers ) and the A / S 32A-36 Amphibious Assault Crash Crane (AACC, for amphibious) Attack ships ). The A / S 32A-35 was introduced in 1989, replacing the NS-60/50; the A / S 32A-36 was introduced in 1993 and replaced the HCC-30/50. From March 1996 to June 1997, a modernization program was carried out at Naval Air Station Patuxent River . The engine drive and connected systems were improved due to frequent breakdowns. The designation for the modernized cranes changed to A / S 32A-35A and A / S 32A-36A.

The vehicles are equipped with a diesel-electric drive from Detroit Diesel . The liquid-cooled, turbo - charged six - cylinder drives a generator . The generator generates electricity for the electric motors for vehicle movement, the crane boom and the electric wire rope hoist . The central and rear axles of the three axles with six air-sprung tires are each driven by an electric motor. The maximum speed is 8 km / h. The hydraulic steering takes place via the front and rear wheels. The rear axle rotates in the opposite direction to the front axle in order to enable a small turning circle . Since the vehicles remain on the flight deck all the time , they are protected against corrosion due to the effects of salt water . The vehicle can be operated from the cab or via remote control .

Aircraft Carrier Crash Cranes and Amphibious Assault Crash Cranes differ mainly in the crane structure. The A / S32A-35 is 10.4 m long × 4.9 m wide × 10.2 m high and weighs 60,550 kg. The crane has a maximum carrying weight of 34,000 kg with the main winch and 4,500 kg with the auxiliary winch. The A / S32A-36 is 9.1 m long × 4.6 m wide × 7.6 m high and weighs 41,500 kg. The crane has a maximum carrying weight of 32,000 kg.
