Working with a crane is dangerous even with the best gear and a well-trained crew. Safety on the job is always a concern.
Details of a new wireless surveillance camera designed to be mounted anywhere along the crane boom or on the hook block with the use of magnets and a safety lanyard have recently been released by GM Engineering Services. They've named the camera system HoistCam. Because the camera is not permanently affixed, it can be unattached and reattached as needed and where needed in a timely manner.
Often, when loading or unloading a vessel, the crane operator is lifting deep in a hold or is otherwise out of the line of vision, working with the aid of a signalman or with a permanently set camera system operated with a joystick. With HoistCam, the operator views a screen from inside the cab without using a joystick. In essence, the operator sees what the moving hook block, for example, "sees."
Crane lift accidents involving poor visibility are not uncommon. Damage incurred is usually to the vessel hull or to cargo, and this is bad enough, but even one human injury or fatality is one too many. The HoistCam trials and demonstrations I've seen show safety and efficiency benefits in shipping and tugboat work; it's not difficult to imagine how this type of visual aid might be used for safer fishing operations.
