Underwater automatic lifting hook
By Christian Shelton11 May 2021
Spanish smart lifting solutions company Elebia Autohooks has launched the subsea hook – an automatic hook for underwater lifting applications.
The hook is designed with a marine configuration and has been built from highly durable materials to withstand use in the tough underwater environment.
The printed circuit board (PCB) and the lithium ion battery are removed from the automatic hook. They are placed in a watertight cylinder – although this remains out of the water at all times in order to maintain radio communication with the hook’s remote control. In addition, this cylinder also features an external radio frequency antenna and LED status indicator, providing visual confirmation of hook status at all times.
The motor, which remains in the marine-configured hook, is isolated by an internal cylinder from the possible influence of water within the frame structure and is hermetically sealed for additional protection.
The subsea automatic hook and the subsea cylinder are connected by a transmission cable of up to 30 metres.
