Aerocrane: A hybrid LTA aircraft for aerial crane applications [PDF]
, 1975 The Aerocrane, a hybrid aircraft, combines rotor lift with buoyant lift to offer VTOL load capability greatly in excess of helicopter technology while eliminating the airship problem of ballast transfer. In addition, the Aerocrane concept sharply reduces

Design Optimization of Knuckle Joint Crane Lifting Mechanism by Using Particle Swarm Optimization
Osmaniye Korkut Ata Üniversitesi Fen Bilimleri Enstitüsü DergisiMobile cranes are specialized machines designed for lifting and moving heavy loads. They feature either a wheeled or tracked chassis and are widely used in industries such as construction, heavy manufacturing, energy, and maritime operations. These cranes utilize hydraulic systems and mechanical forces to lift objects from elevated or confined spaces ...

STS payload ground handling mechanism at John F. Kennedy Space Center [PDF]
, 1985 The payload ground handling mechanism (PGHM), which lifts payloads out of the payload canister that brings them to the launch pad, is described. The PGHM then loads the payloads into the orbiter through the open payload bay doors.
