<p>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.</p> |
