  • Tractor lift detection system for gantry cranes
    Patent number: 8421640
    Abstract: An automatic signaling system to prevent a tractor from being accidently lifted with the cargo by a ship to shore gantry crane. The embodiment includes multiple sensors to detect a lifted condition and radio output upon a lifted condition. The radio output channel is determined by an automatic identification system that identifies the crane the tractor is under. Upon receiving a lifted signal the cranes hoist will be stopped and disabled but will still allow lowering until the lifted signal stops.
