A safety system comprises a load detection sensor 5 retrofitable on a safety hook 1, a transmitter 3 arranged to convey a load status signal; processing means 2 for analysing the load status signal; a receiver for receiving the load status signal and being operably connected to the processing means 2; warning means 12 arranged to generate notifications; and a power source for providing energy to the transmitter, the receiver, and the processing means. The load detection sensor 5 is arranged to generate a load status signal which is sent by the transmitter 3 to the receiver and then analysed by the processing means so that when the load status signal indicates that a load is undetected or that the safety hook 1 is connected, the warning means 12 are either inactive or generate a first notification but when the pressure status signal indicates that a load is detected or that the safety hook 1 is disconnected, the warning means 12 generate a second notification. |
